Introduction: Engineered To Do One Job Perfectly
Engineered To Do One
Job Perfectly.
The GP 2000 grinder
pump, the heart of the
E/One Sewer System,
provides wastewater
storage, grinding, and
pumping in a single unit.
Translation: it lowers
operating costs, the cost
of waste collection, and reduces maintenance.
The E/One Sewer System grinder pump is engineered to one thing
perfectly and in the process will help communities manage their growth
and maintain quality of life.
How Does It Look from Where You Are?
Aesthetics are a major consideration for homeowners. The E/One
Sewer System is virtually out of sight - the only visible part is a low-
profile cover that blends seamlessly into the environment but provides
easy access for servicing operations.
A Sense of Site.
Multi-branch E/One Sewer Systems serve the entire community and
give engineers, developers, community planners, and homeowners the
freedom to sewer anywhere, on any kind of site.
The Price is Right.
E/One can solve sewering problems and replace failing septic systems
at approximately half the cost of conventional gravity sewers. E/One
Sewer Systems sharply reduce both front-end costs and ongoing
maintenance costs.
The High Cost of Septic Systems.
While septic systems may be a common way of disposing of
residential sanitary waste, they are, at best, a temporary solution and
come at a high cost to public health. All over America, septic systems
have degraded ground and recreational water, creating serious safety
problems. Because of failing septic systems, water is not safe to drink.
Children are not free to play near contaminated lakes and streams.
Outbreaks of waterborne disease become common. Quality of life is
eroded. In addition, failing septic systems decrease real estate values.
E/One Sewer Systems can go wherever septic systems were initially

used, reclaiming water quality and quality of life while providing an
efficient, cost-effective solution to wastewater disposal and treatment.
In fact, communities retrofitting with E/One Sewer systems have
reported dramatic improvements in coliform levels in as little as 30
days after installation.

Introduction : Why It's Better
The E/One Sewer System. What it is.
How it works. Why it's better.
In the world of sewer system
technology, less is more. The E/One
Sewer System requires only a shallow
trench and small 2- to 4-inch diameter
piping. So, unlike conventional gravity
central sewers, which use 24-inch pipe
and require deep excavation, the
E/One Sewer System is not destructive
to the landscape's natural or built
features. It also costs significantly less
to install and operate than a gravity system. It requires less
maintenance. But it guarantees big results.
Here's the idea behind the E/One Sewer System: Both the gravity
sewer system and the E/One Sewer System are known as central
sewer systems. (Septic systems fall into a whole other category of
waste disposal - see "The High Cost of Septic Systems" on the
following page.) Most cities and many villages use central sewering,
which simply means that waste is transferred, usually by a pipe or
main, to a central treatment plant.
Gravity sewers are the "original" central sewers, with origins in the
Roman aqueducts. Unfortunately, the technology behind gravity
sewers is also centuries-old: they're bulky systems using a large main
and can require major excavation to install. They must be accurately
placed and bedded along a continuous downward grade. Plus they're
expensive and not entirely efficient in transporting waste because they
can tend to leak.
The more advanced E/One Sewer System employs highly
sophisticated technology and has become known for its reliability,
minimal maintenance, low upfront costs, reduced operating expenses,
and ability to be installed at any site, regardless of the challenges of
topography. And only the E/One Sewer System with its GP 2000
grinder pump overcomes the challenges of low-pressure systems,
performing dependably day in and day out.
Small is Beautiful.
Conventional gravity sewers use a 24-inch large-diameter pipe, or
main, which requires major excavation and severely disrupts the
landscape and any built structures such as lawns, driveways, and
plantings. The E/One Sewer System uses an unobtrusive small-
diameter 2- to 4-inch main installed right below the frostline, following
the natural topography of the land.

Introduction : Features & Benefits
E/One's GP2000 Grinder Pump Station
The GP 2000 grinder pump station has evolved from everything we've
learned in more than a quarter century of engineering low-pressure
sewer systems.
The pump stations incorporate the grinder pump, motor control and
level sensing device integrated into a compact unit, easily removable
for servicing when necessary.
The progressing cavity pump itself is based on the Moineau principle.
A rotor turns within a stator, creating a sequence of sealed chambers.
The precision cast and polished stainless steel rotor moves
wastewater through these chambers at a nearly constant flow, over a
wide range of conditions - from negative to abnormally high heads.
Turning at just 1725 rpm, the one horsepower motor can pump fluid
through miles of small-diameter piping and elevation changes of over
138 feet.
In addition, the geometry of the pump not only produces a near-vertical
pump curve, but allows passage of round solids without clogging.
Because of the low rpm and highest quality components, we
experience the lowest service call rate in the industry. More than eight
years mean time between service calls is typical.
Some Key Advantages:
High Heads/Negative Heads. Reliable operation from negative head
to 138+ feet of total head for continuous duty reduces the number of
lift stations and pipe sizes. This cut costs - both initially and in long-
term operation and maintenance.
Constant Flow. The systems pressurizes to be overcome by any
given grinder pump in a low-pressure system vary dramatically over
the course of a day. Only E/One's progressing cavity pump readily
accommodates these pressure variations while maintaining a nearly
constant flow without ever operating at "near shut off" - thus avoiding
the wear and motor burn-out suffered by other pump types.
High Grinding Torque. Our unique pump system, driven by a one-
horsepower motor turning at 1725 rpm, produces grinding torque equal
to a two-horsepower pump turning at twice the speed.
Low Energy Consumption. Pump is activated automatically. Runs for
short periods. Typical annual energy consumption equals a 40-watt
light bulb.
Low Maintenance Submersible Motor. Low maintenance and long
http://www.eone.comlsewerlintro/features/ content.html

life are the hallmarks of our air-filled motor. Permanently lubricated ball
bearings and Class F insulation eliminate the need for periodic oil
changes and oil disposal costs required by oil-filled submersible
motors.
Large Diameter Grinder Assembly. Almost twice the diameter of
most other types of pumps, contributing to a dramatic reduction of
inflow velocity for less wear and no clogging or jamming.
No Maintenance. Self-cleaning static level sensors require no
preventative maintenance. Because of our unique, near constant
discharge rate, no main line flushing is required in a properly designed
system.
Corrosion Resistance. E/One's stainless steel ball type discharge
valve and piping won't corrode like copper or galvanized, and hold up
years longer. No corrosion, no maintenance.
Dependability. E/One pumps typically run eight to 10 years between
service calls with more than 30 years of in-ground experience.
Provides for environmentally sound wastewater management.
The GP 2000 grinds waste material into small particles. This enables
the use of inexpensive, small-diameter pressure pipes, buried at
shallow depths, to transport wastewater to a suitable processing site.
Result: Ground water contamination from failing septic tanks can be
eliminated.
Serviceability. Our unique core design eliminates the need for in-field
troubleshooting and pump servicing. This means lower maintenance
costs and minimum homeowner inconvenience.
Engineered low-pressure systems: repealing the law of gravity.
Gravity sewers are no longer the rule for solving wastewater problems.
With huge savings in front-end costs, and a much gentler footprint on
the environment, gravity-independent Environment One low-pressure
sewer systems are revolutionizing the field.
At the heart of the system is the E/One progressing cavity grinder
pump - with high heads that eliminate costly lift stations, and a
robust, powerful design that translates into the industry's highest levels
of reliability, availability and maintainability.
Nobody can touch our curve.
In a low-pressure system, constant, predictable pump output is the
foundation for proper hydraulic design. It enables the engineer to
minimize retention time, pump wear, and keep scouring action at
http://www.eone.comlsewer/intro/features/ content.html

effective levels.
Environment One's semi-positive displacement, progressing cavity
pump has a nearly vertical H-Q curve. It is by far the most "forgiving"
pump design - providing predictable flow over the full range of typical
system pressures; strengths critical in a large-scale, low-pressure
sewer. Click here to view a PDF of our performance curve.
E/One's superior high head capability allows a system with few, if any,
lift stations. And, it easily accommodates additional future connections
without compromising system performance.
These E/One pump characteristics translate into:
· Predictable hydraulic design
· Low collection system capital costs
. Less maintenance
. Lower operating costs
Leading the industry we invented.
Environment One not only pioneered the low-pressure sewer system,
but consistently leads the industry both in sales and innovation. The
company is dedicated to Total Quality and Continuous Improvement,
as evidenced by the GP 2000 Series. Today, there are more than a
quarter million users worldwide.
Sewer anywhere, save thousands, virtually service-free.
Driven by the remarkable GP 2000 grinder pump, E/One Sewers give
engineers, developers, sanitarians, and land planners unprecedented
new freedom in land usage.
And they're so much easier to install. Front-end costs are reduced by
as much as 70 percent.
The GP 2000 System reduced all forms of sanitary waste to a non-
clogging slurry and pumps it through a network of small-diameter
pipes. Since gravity is replaced by the power of the pump, sewer
systems need not run downhill nor require large-diameter pipes, deep
trenches, multiple booster stations - or their associated costs.
A system powered by the GP 2000 pump converts formerly cost-
prohibitive building sites into cost-effective reality. "Problem areas,"
with high ground water, elevation changes or impenetrable bedrock,
are transformed into valuable, developable real estate.
Of course, E/One's low upfront cost advantages apply to conventional
building sites as well.

Installation
The Environment One Grinder Pump is a well-engineered, reliable and
proven product: proper installation will assure years of trouble-free
service. The following instructions define the recommended procedure
for installing the Model 2014 Grinder Pump. These instructions cover
the installation of units with and without accessways.
This is a sewage-handling pump and must be vented in accordance
with local plumbing codes. This pump is not to be installed in locations
classified as hazardous in accordance with National Electric Code,
ANSI I NFPA 70. All piping and electrical systems must be in
compliance with applicable local and state codes.
1. REMOVE PACKING MATERIAL
The User Instructions must be given to the home owner. Hardware
supplied with the unit, if any, will be used at installation.
2. TANK INSTALLATION
Lift the station using only the methods described on page 9, "Lifting
http://www.eone.comlsewer/productsI20 14/ content.html
10/512004
E/One Sewer Systems - Products
. .
Page 3 of 11
Instructions". The tank is supplied with a standard grommet for
connecting the 4" DWV (4.50" outside Dia.) incoming sewer drain.
Other inlet types and sizes are optional (caution 4" DR-35 pipe is of
smaller diameter and won't create a water tight joint with the standard
grommet). Please confirm that you have the correct inlet before
continuing. If a concrete ballast is attached to the tank lift only by the
lifting eyes, (rebar) embedded in the concrete. Do not drop, roll, or lay
tank on its side. This will damage the unit and void the warranty.
If the tank has no accessway (Fig. 1b): (Indoor Installation):
The pump may be installed on or in the basement floor (see fig. 1 b). If
the tank is to be set on the floor it must be a flat and level bearing
surface. If the tank is to go into the basement floor, it must be
anchored to prevent unit from floating due to high ground water (see
Chart 1, page 12 for weight).
If the tank is to go in the floor:
A hole of the correct width and depth should be excavated. The tank
must be placed on a 6" bed of gravel made up of naturally rounded
aggregate, clean and free flowing, with particle size not less than 1/8"
or more than 3/4" in diameter. The wet well should be leveled and
filled with water prior to pouring the concrete to prevent the tank from
shifting. If it's necessary to pour the concrete to a level above the inlet,
the inlet must be sleeved with an 8" tube before pouring.
There must be a minimum clearance of three feet directly above the
tank to allow for removal of the pump core.
If the tank has an accessway (Fig. 1a):
Excavate a hole to a depth, so that the removable cover extends
above the finished grade line. The grade should slope away from the
unit. The diameter of the hole must be large enough to allow for a
concrete anchor. Place the unit on a bed of gravel, naturally rounded
aggregate, clean and free flowing, with particles not less than 1/8" or
more than 3/4" in diameter. The concrete anchor is not optional. (See
Chart 1 on page 12 for specific requirements for your unit)
The unit should be leveled and the wet well filled with water to the
bottom of the inlet to help prevent the unit from shifting while the
concrete is being poured. The concrete must be vibrated to ensure
there are no voids.
If it is necessary to pour the concrete to a higher level then the inlet,
the inlet must be sleeved with an 8" tube before pouring.
If your unit is a model taller than 93" it may be shipped in two sections,
requiring field assembly. See Field Joint Assembly Instructions on
page 8 for additional information.
3. INLET PIPE INSTALLATION
http://www.eone.comlsewer/productsI20 14/ content.html
10/5/2004
E/Pne Sewer Systems - Products
Page 4 of 11
Mark the inlet Pipe 3 1/2" from the end to be inserted. Inlet pipe should
be chamfered and lubricated with a soap solution. Lubricate the inlet
grommet with soap solution as well. Insert the pipe into the grommet
up to the 3-1/2" mark. Inspect to ensure the grommet has remained
intact and in place.
4. DISCHARGE
The use of 1-1/4" PVC pressure pipe Schedule 40 and polyethylene
pipe SOR 11 or SIOR 7 are recommended. If polyethylene is chosen
use compression type fittings to provide a smooth inner passage. It is
recom-mended that a Redundant Check Valve Assembly (E/One part
no. PC0051 GXX) be installed between the pump discharge and the
street main on all installations. Never use a ball type valve as a check
valve. We recommend the valve be installed as close to the public
right-of-way as possible. Check local codes for applicable
requirements.
CAUTION: Redundant check valves on station laterals and anti-
siphonlcheck valve assemblies on grinder pump cores should not be
used as system isolation valves during line tests.
If the tank has no accessway (Indoor Installation):
The discharge connection is a 1-1/4" male NPT. The discharge piping
must incorporate a shut-off valve and a union with a minimum
pressure rating of 160 PSI, or a suitable piping disconnect to allow for
removal of the pump core. The valve should be of the type that
provides a full-ported passage (Le. a ball or gate valve). A standard 1-
1/4" union or a com-pression type coupling should be used as a
disconnect joint.
If the tank has an accessway:
There is a ball valve and a quick disconnect pre-installed in the
accessway. There is a 1-1/4" female NPT discharge connection on the
outside of the tank 41" above the bottom of the tank.
5. BACKFILL REQUIREMENTS
Proper backfill is essential to the long term reliability of any
underground structure. Several methods of backfill are available to
produce favorable results with different native soil conditions.
The most highly recommended method of backfilling is to surround the
unit to grade using Class I or Class II backfill material as defined in
ASTM 2321. Class 1A and Class 1 B are recommended where frost
heave is a concern, Class 1 B is a better choice when the native soil is
sand or if a high, fluctuating water table is expected. Class I, angular
crushed stone offers an added benefit in that it needs minimal
compaction. Class II, naturally rounded stone, may require more
compactive effort, or tamping, to achieve the proper density.
If the native soil condition consist of clean compactible soil, with less
http://www.eone.comlsewer/products/20 14/ content.html
10/512004
E/One Se~er Systems - Products
Page 5 of 11
than 12% fines, free of ice, rocks, roots, and organic material it may be
an acceptable backfill. Such soil must be compacted in lifts not to
exceed one foot to reach a final Proctor Density of between 85% and
90%. Non-compactible clays and silts are not suitable backfill for this
or any underground structure such as inlet or discharge lines. If you
are unsure of the consistency of the native soil it is recommended that
a geotechnical evaluation of the material be obtained before specifying
backfill.
Another option is the use of a flowable fill (Le., low slump concrete).
This is particularly attractive when installing grinder pump stations in
augured holes where tight clearances make it difficult to assure proper
backfilling and compaction with dry materials. Flowable fills should not
be dropped with more than four feet between the discharge nozzle and
the bottom of the hole since this can cause separation of the
constituent materials.
6. VENTING
The unit must be properly vented to assure correct operation of the
pump. If you have an indoor unit it can be vented through the 2" port
supplied at the top of the wet well or through the incoming sewer line
with a 2" pipe (the vent must be within four feet of the grinder pump,
and before the first change of direction fitting).
The outdoor units are supplied with a vent pipe from the wet well to the
top of the accessway. Failure to properly vent the tank will result in
faulty operation and will void the warranty.
7. ELECTRICAL CONNECTION (Supply panel to E/One alarm panel)
Before proceeding verify that the service voltage is the same as the
motor voltage shown on the name plate. An alarm device is to be
installed in a conspicuous location where it can be readily seen by the
homeowner. An alarm device is required on every installation. There
shall be no exceptions.
Wiring of supply panel and Environment One Alarm Panel shall be per
figures 2a and 2b, alarm panel wiring diagrams and local codes.
8. ELECTRICAL CONNECTION (Pump to Panel) (Fig. 4)
The Environment One GP2000 grinder pump station is provided with a
cable for connection between the station and the alarm panel, (The
Supply Cable). The supply cable is shipped inside the station with a
small portion fed through the cable connector mounted on the wall of
the fiberglass shroud. The supply cable, a six conductor tray cable,
meets NEC requirements for direct burial as long as a minimum of 24"
burial depth is maintained. Those portions of the cable which have less
than 24" of cover must be contained in suitable conduit. This includes
the vertical portion dropping to a 24" depth at the station and the
length rising out of the ground at the control panel. NOTE: Wiring must
be installed per national and local codes. Conduit must enter panel
http://www.eone.comlsewer/products/20 14/content.html
10/5/2004
E/9ne Sewer Systems - Products
Page 6 of 11
from bottom and be sealed per NEC section 300.5 & 300.7.
Sa. Procedure for installing E/One supply cable
1. Open the lid of the station, locate the cable and the feed-thru
connector on the wall of the shroud. If the station has a field joint
and was delivered in two pieces be sure the 2 halves of the EQO
are securely assembled together. Loosen the nut on the
connector and pull the supply cable out through the connector
until it hits the crimped on stop feature on the cable,
approximately 24" from the EQO.
IMPORTANT: All but 24" of the cable must be pulled out of the
station, and the portion of the cable between the EQD and the
molded in cable breather should be secured in the hook provided
to ensure that the pump functions properly. Do not leave the
excess cable in the station.
2. Retighten the nut. This connection must be tight or ground water
will enter the station.
3. Feed the wire through the length of conduit (contractor provided)
which will protect it until it is below the 24" burial depth.
4. Position the conduit vertically below the cable connector along
side of the station reaching down into the burial depth. Attach the
small fiberglass guard (Protective Shroud) provided with the
station to protect the exposed cable where it enters the station.
Four self-tapping screws are provided.
5. Run the cable underground, in a trench or tunnel, to the location
of the Elane panel. Leave a 6-12 inch loop of cable at each end
to allow for shifting and settling. Connections made at the panel
are shown in the panel wiring diagram (Fig. 2a and 2b).
9. DEBRIS REMOVAL
Prior to start-up test procedure, the core must be removed and the
incoming sewer line flushed to force all miscellaneous debris into the
tank. Next, all liquid and debris must be removed. Once tank is clean,
reinstall the pump and proceed with the test.
10. TEST PROCEDURE
When the system is complete and ready for use, the following steps
should be taken to verify proper installation and operation:
a. Make sure that the discharge shutoff valve is fully open. This
valve must not be closed when the pump is operating. In some
installations there may be a valve, or valves, at the street main
that must also be open.
b. Turn ON the alarm power circuit breaker.
c. Fill tank with water until the alarm turns ON. Shut off water.
d. Turn ON pump power circuit breaker. Pump should immediately
turn on. Within one minute the alarm will turn off. Within three
minutes the pump will turn off.

1. Carefully clean and dry both accessway flanges with solvent.
IMPORTANT: Sealing surfaces must be dry to ensure the sealant
adheres correctly.
2. Starting at one hole of tank flange, apply two layers of Sika Tape
around the inside half of the flange. Align the outside edge of the tape
with the bolt circle. Move to the adjacent hole and apply one layer of
Sika Tape around the outside of the flange. Align inside of tape with
the bolt circle. Remove the backing paper as you lay the adhesive on
the flange. Do not stretch Sika tape during application, it may result in
a leak. The tape should overlap at the end by approximately 112 inch,
as shown in Fig. 5a. If a section of Sika Tape is misapplied, the bad
section may be cut out and replaced. Cut away the poorly laid portion
cleanly with a knife and be sure to over lap the tape at each end about
1/2 inch.
3. Using the tool provided, punch a hole through the tape at each of
the 16 existing bolt holes in the flange. Be careful to keep the exposed
sealant clean and dry.
4. Insert three of the sixteen 3/8-16 x 1-1/2" long bolts, with a flat
washer, into the flange attached to the upper part of the accessway.
These will act as guides while aligning the bolt pattern of the two
flanges.
5. Support the upper accessway section a few inches over the tank
with the green stripes on each lined up. Once aligned, lower the upper
section onto the mating flange using the three bolts to guide it to the
proper position (Fig. 5b).
6. Insert the remaining 13 bolts with flat washers into the flanges.
Place a flat washer and elastic stop nut on the end of each bolt,
turning the nut on just enough to hold the washer in place.

7. Tighten up the bolts until the sealant begins to squeeze out from
between the flanges. To ensure a consistent, sturdy seal tighten them
in the following sequence: 1, 9; 5, 13; 3, 11; 7, 15; 2, 10; 4, 12; 6, 14;
8, 16. Always be sure to tighten one bolt and then the bolt at the
position 1800 from it, see figure 1 for position numbers.
8. Using the same sequence as in step 7 tighten each bolt to 60 inlbs.
Visually inspect the joint, each bolt and each nut should have a flat
washer between it and the flange, and a uniform amount of sealant
should be protruding from the seam along the entire perimeter.
In the event that there are any voids in the sealant, the joint may leak.
Take corrective actions if necessary and be sure that the joint is leak
free before continuing.
9. Install the vent pipe extension piece which was shipped inside the
upper piece of the accessway. Push the extension pipe into the bell
mouth fitting on the pipe installed in the wet well tank. Be sure the pipe
is seated correctly. Slide the top end of the extension pipe into the
receptacle on the bottom of lid.
Lifting Instructions
Failure to follow these instruction completely will void warranty.
Transporting unit to installation site:
Always lift a unit from the bottom for the purpose of transportation. The
station should be received attached to a pallet for this purpose. Never
roll a station or move it on its side.
1. No Ballast, No Eye bolts (Ballast to be poured in place):
If the concrete anchor is to be poured while the station is in place and
it has no eye bolts, lift the unit by securing two (2) 20 foot flat or round
eye slings around the station. Loop the slings around the station and
use an approprate lifting beam or tie-down strap to ensure the safety
of the station and people close to the unit. (see below)
2. No Ballast, Factory Installed Eye Bolts (Ballast to be poured in
place ):
If the concrete anchor is to be poured while the station is in place lift
the unit by securing straps to the eyebolts supplied on the lower
flange, as shown below. Keep station oriented vertically to avoid any
damage. Only lift from the eyebolts to put unit in hole, not for moving
any distance. (see below)
3. Precast Ballast:
Never lift a station that has a ballast attached by any means except the
rebar hooks. The weight of the concrete will damage the station if you
attempt to lift it from any part of the station. (see below)

Adjusting the Height of a 2000 Series Grinder Pump Station
REMOVE EXISTING COVER ASSEMBLY (Fig. 6)
If your existing station has a welded-on cover shroud you will need the
appropriate replacement cover kit (see Table 2).
1. Turn off all power to the grinder pump station.
2. Remove the tank lid and the electrical shroud.
3. Unplug the electrical quick disconnect (EQD) and remove the EQD
from the supply cable. Note: DO NOT CUT CABLE. Loosen liquid tight
cable connector and pull the supply cable out through the connector
on the side of tank.
4. Tape the pump breather cable to the vent pipe in the tank.
5. Remove the soil around the tank, exposing three of the tank
corrugations below grade. Use caution not to damage buried cable.
6. Remove existing cover shroud.
6a. Welded-on shroud (standard) - Using a hand saw, cut the tank in
the valley between the two corrugations at grade, discard existing
welded-on shroud and attached corrugations (shroud is not to be
reused). Caution: Be careful not to cut either the vent pipe or the pump
breather cable.
6b. Clamped-on shroud - Remove band clamp and cover shroud.
REDUCING STATION HEIGHT (Fig. 7)
7. Using a hand saw, cut the tank in the valley between the two
corrugations at grade.
8. Cut vent pipe 4 %" above the cut made on the tank. Proceed to step
16.
INCREASING STATION HEIGHT (Fig. 8 and Fig. 9)
9. Remove the soil around the tank exposing it 18" deeper than the
extension being installed. For example, if you have a 2' extension (not
including the coupler) you must dig down 3'6" minimum from grade; if
http://www.eone.comlsewer/products/20 141 content.html

E/One Se.wer Systems - Products
Page 10 of 11
you have a 4' extension (not including the coupler) you must dig down
5'6" min"imum from grade. Use caution not to damage buried cable.
10. Measure from grade down 2' (for a 2' extension) or 4' (for a 4'
extension) and mark accessway. Using a hand saw, cut the tank in the
valley between the two corrugations that are closest to your mark.
Note: Make sure the welded-on shroud of the extension will be at
grade level. Be sure you are not cutting into the wet well and you must
have two corrugations below your cut, if there are less than two
corrugations, this extension kit can not be used. Caution: Be careful
not to cut either the vent pipe or the pump breather cable.
11. Attach the vent pipe extension with the 2" vent coupling, bringing
the vent well above grade.
12. Clean all dirt and debris from top four corrugations on tank. Install
the 24" coupler a-ring on the tank between the top two corrugations
with the white or yellow line facing out and on top.
13. Lube extension coupler and coupler a-ring with pipe lube or dish
soap.
14. Manually press coupling evenly over lubricated a-ring. If additional
force is needed, place a plywood cover over the accessway and apply
gentle mechanical pressure to the coupler. Note: Care must be used
when pushing down on the coupler. Excessive force or impact may
result in damage and leakage.
15. Frequent visual inspections during installation must be performed
to determine when the tank has fully engage the coupler.
INSTALL REPLACEMENT COVER ASSEMBLY (Fig. 10)
16. Clean top corrugation on accessway extension and mating surface
of replacement shroud with acetone.
17. Liberally apply the silicone sealer provided to the under side of the
replacement shroud where it will come in contact with the accessway
extension.
18. Lube wet well vent grommet and vent pipe extension with pipe
lube, non-grit hand cleaner or dish soap and slide vent pipe through
grommet until tank shroud seats to accessway.
19. Place SS band clamp around top corrugation and the replacement
shroud. Tap with a mallet around clamp to help seat the clamp. Torque
stud assembly on band clamp to a maximum 125 inlb.
20. Reinstall the supply cable, EQO**, tank lid and electrical shroud
and tighten cable connector. (**See "EQO wiring order," Table 1)

21. Follow start-up procedures to ensure proper pump operation (you
will find the start-up instructions in our service manual or the station
installation instruction guide).
NOTE: IF EXISTING ACCESSWAY HAS ONLY 2 CORRUGATIONS
(Fig. 11)
- If the coupler will not engage completely because the discharge
piping is in the way, and it doesn't have a cut out, you will need to cut
a slot in the coupler.
- Using a hand, reciprocating or hole saw, cut an arch in the coupler;
the cut-out is not to exceed 5.50" tall or 5.00" wide.

General Applications
The size, efficiency and operating
economy of the GP 2014 make it an
ideal choice for multiple dwellings,
waterfront property, subdivision
developments and marinas. The GP
2014 is ideally suited for both new and
existing communities.
General Features
The GP 2014 Grinder Pump is a
complete unit that includes: two
grinder pumps with check valves,
HDPE (high density polyethylene) tank
and controls. The GP 2014 is pack-
aged into a single complete unit, ready
for installation.
All solids are ground into fine particles,
allowing them to pass easily through
the pump, check valve and small-
diameter pipelines. Even objects that
are not normally found in sewage,
such as plastic, rubber, fiber, wood,
etc., are ground into fine particles.
The 1 1/4-inch discharge connection
is adaptable to any piping materials,
thereby allowing it to meet local code
requirements.
The tank is made of tough corrosion-
resistant HDPE. The optimum tank
capacity of 150 gallons is based on
computer studies of water usage
patterns. A single GP 2014 is ideal for
up to four average, single-family
homes, and can also be used for up
to 12 average, single-family homes
with the consent of the factory. This
model can accommodate flows of
3000 GPD.
The internal check valve assembly,
located in each grinder pump, is
custom-designed for non-clog,
trouble-free operation.
The grinder pump is automatically
activated and runs infrequently for
very short periods. The annual energy
consumption is typically that of a 40-
watt light bulb.
Units are available for indoor and
outdoor installations. Outdoor units
are designed to accommodate a wide
range of burial depths.
Operational Information
Motor
1 hp, 1,725 rpm, high torque, capaci-
tor start, thermally protected, 120/
240V, 60 Hz, 1 phase
Inlet Connections
4-inch inlet grommet standard for
DWV pipe. Other inlet configurations
available from the factory.
Discharge Connections
Pump discharge terminates in 1 1/4-
inch NPT female thread. Can easily
be adapted to 1 1/4-inch PVC pipe or
any other material required by local
codes.
Discharge *
15 gpm at 0 psig (per pump)
11 gpm at 40 psig (per pump)
9 gpm at 60 psig (per pump)
Control Panel
This station is designed to use the
Alternating Control Panel, MOD T260.
Overload Capacity
The maximum pressure that the pump
can generate is limited by the motor
characteristics. The motor generates
a pressure well below the rating of the
piping and appurtenances. The
automatic reset feature does not
require manual operation following
overload.
