Introduction 1–2
Basic Operation
The grinder pump is designed to grind and pump domestic sewage. The pump is a semi-
positive displacement, progressing cavity pump. The grinder pump consists of a pump
assembly with an integral sewage grinder and shredder device. The pump traps a column
of air in the sensing bell for the on-off pressure switch. When water in the tank reaches the
normal turn-on level, the pressure in the sensing line closes the electrical contact points. The
relay coil is energized and the relay contact points close, providing electrical power to the
pump motor. When the motor starts and runs, the grinder pulverizes any solids. The slurry is
then pumped until the liquid in the tank is lowered to the shut-off level. This reduces pressure
on the diaphragm of the on-off switch, which opens the electrical contacts and removes power
from the motor.
In the event of a pump failure, the liquid in the basin rises and activates an alarm pressure
switch. The electrical contacts close, activating the alarm indicator (light and/or buzzer). The
alarm alerts the homeowner about a pump problem.
Safety Warnings

Troubleshooting 2–1
Chapter 2 — Troubleshooting
Site information is vital to proper diagnosis of a pump failure and returning the station to
operation. When a pump requires service, perform an inspection of the site rst.
Site Survey — Alarm Panel
1. Observe the site. Record the following on the service tag:
• Customer information
• Date and time
• Alarm status
• Is the pump running (without opening the station)?
2. Open the alarm panel enclosure. Record the following on the service tag:
• Is the inside of the alarm panel dry and free from moisture?
• Are any breakers tripped?
• Was the panel installed correctly (penetrations on bottom, sealed conduits, etc.)?
• Is service needed to the panel?

Supply Voltage Checks
The Environment One grinder pump is equipped with a 1725 rpm, 1 hp, multi-tap 120V/240V
motor. The operating voltage parameters of the motor are plus or minus 10 percent of the
specic application, equating to 108V to 132V in the 120V application and 216V to 264V in the
240V application.

Troubleshooting 2–4
Buck Boost Transformer — 240V Application
If the supply voltage on a 240V application is 208V 3 phase, a buck boost transformer must be
installed. Not installing the transformer will shorten the life of the motor signicantly.
A buck boost transformer manipulates one leg of the supply voltage. It will raise the one leg
approximately 32V (240V – 208V = 32V), which would give approximately 152V on one leg
and 120V on the other to equal 240V. This is important to know because one leg of the main
supply voltage is shared with the alarm circuit, which is a 120V circuit with an operating range
of 108V to 132V.
Connect the higher of the two legs to the pole of the double pole breaker that has the pump L2
(Black) wire tied to it. The pole with the pump L1 (Red) wire is the pole shared with the alarm
breaker. Failure to connect the wires in this conguration will result in a high voltage condition
on the alarm circuit board, subsequently resulting in failure of the circuits.
Continuity Test
All continuity readings should be taken after the power is turned off and veried with a
voltmeter. With the pump power off, set an ohmmeter (Wavetek #5XP or equivalent) to the
2–meg or 2000K ohm scale. All readings for 120V pumps are performed in the 2000K or 2M
scale unless indicated otherwise. The meter must be in the 200K scale to read the coil and
alarm circuits. Auto-ranging meters must be set manually.
Identify the wires that come from the pump and go to the panel. The test points on Tables 2-3
through 2-6 refer to pump wires only and can be tested at the panel or EQD. Allow at least 5
seconds for the meter to obtain a stable reading. Note any incorrect readings on the service
tag.
Note: Ground to Blue and Ground to Yellow checks are true for two-relay conguration simplex
and duplex alarm panels. Four-relay conguration simplex boards, E/One Sentry Protect
and E/One Sentry Protect Plus panels will show “open” on these checks in or out of water.
Megohmmeter/Cable Insulation Integrity Check
1. Separate the EQD at the station and remove all but the ground wire inside the panel.
2. Using a 500V Megohm meter, check for shorts between all wires:
Good: 500M or higher
Marginal: Between 200M and 500M
Bad: Below 200M
3. If a bad reading is detected, isolate the cable by removing the EQD insert and
retesting the cable.
4. If the bad reading goes away, replace the insert and retest the wires to ensure that
the new EQD insert resolved the problem.
Always retest after repairs. If the readings don’t change, replace the cable.
Note: If moisture is present in the EQD, replace the inserts and clean and dry the housings before
reassembly. If housings are ooded, water may have wicked into the wires and trimming
back the cable may be necessary. If bad readings persist, replace the cable.

Amperage Checks
Using a clamp-on amp meter can be helpful for identifying problems such as a restricted or
blocked discharge line, blown stator, or faulty check valve/anti-siphon.
1. Set the clamp-on amp meter to the appropriate scale.
2. Hook the probe around the black power lead in the alarm panel.
3. With the power on, ll the tank until the pump operates, or press the push-to-run
switch in the alarm panel.
4. Read the current directly. Refer to the following table for troubleshooting.
The gures shown are averages and should be used for approximation because motors,
voltages and amp meters vary. The table displays a comparison of back pressure (psi), ow
(gpm), current draw (amperes) and head (feet of water pressure).
A jammed grinder may trip the circuit breaker or cause the overload protector to cycle. This
causes the pump to cycle on and off and eventually results in an alarm condition. A torn or
worn out pump stator results in a “runs but does not pump” condition and eventually, as the
water rises, causes an alarm. Replace the stator and, if necessary, the rotor.

Site Survey — Tank
1. Open the tank and inspect. Record the following on the service tag:
• Is the station lid above grade?
• Is the tank/accessway ooded? If yes, where did the water enter?
• Was the EQD below water?
• Is the Equalizer hung properly, as high in the tank as possible?
• Are other signs of inltration present?
2. Disconnect and inspect the EQD. Record the following on the service tag:
• Is the EQD dry?
• Is the EQD assembled correctly?
3. Repeat the power-off continuity checks at the EQD.

Troubleshooting 2–9
Possible Causes Troubleshooting Steps
Blocked discharge line,
worn stator or leak in
pump discharge assem-
bly
Check the amperage. If the amperage is high (8 amps or higher), turn off the
pump and check the discharge line for blockage. Conrm that the pump has
not been damaged by disconnecting the discharge piping and recycling the
uid in the tank. Turn the pump power on and check the amperage. If the am-
perage remains high, replace the pump and return the failed pump to shop for
possible repair. If amperage returns to normal, clear blockage in discharge line
and re-check amperage.
If the amperage is low (4.9 amps or less), the pump must be pulled and the
stator (and possibly the rotor) replaced, or the leaking discharge line repaired.
The cause of the stator and/or rotor failure must be determined and corrected
before reinstallation or the pump will fail prematurely again. Chapter 5 – Pump
End describes how to identify and correct causes of stator and rotor wear.
Alarm On — Pump Running but not Pumping
Table 2–8
Possible Causes Troubleshooting Steps
Incorrect voltage Check the voltage at a location nearest the pump, such as the junction box or
EQD. The correct voltage is listed on the pump nameplate. Note: Voltage must
be within 10 percent of nameplate voltage (240V: 216V to 264V; 120V: 108V to
132V). 208V requires a buck boost transformer.
Plugged Equalizer Check the Equalizer tube and ensure it is not crimped or pinched.
Low uid level Check the tank for sufcient uid to operate the pump. Insufcient uid may
indicate a problem with the alarm wiring, alarm sensing line, or alarm switch.
Chapter 8 – Level Sensor and Chapter 9 – Control Cavity describe the steps for
checking the alarm wiring and controls.
Wet or corroded controls Inspect the electrical controls and replace any wet or corroded controls. See
Chapter 9 – Control Cavity.
Inoperative control Test the controls as described in Chapter 9 – Control Cavity.

Table 2–9
Troubleshooting

Troubleshooting 2–10
Possible Causes Troubleshooting Steps
Normal Operation The pump may be grinding material. Wait a few minutes. If the pump does not
quiet down, remove the pump and clean the basin.
Low Voltage Check the voltage level. The voltage is listed on the pump nameplate. Note:
Voltage must be within 10 percent of nameplate voltage (240V: 216V to 264V;
120V: 108V to 132V). 208V requires a buck boost transformer.
Blocked Discharge Check the amperage. If amperage is high (8 amps or higher on 240V; 16 amps
or higher on 120V), turn off the pump and check the discharge line for a block-
age. Conrm that the pump has not been damaged by disconnecting the dis-
charge piping and recycling the uid in the tank. Turn on the pump power and
check the amperage. If amperage remains high, replace the pump and return
the failed pump to shop for possible motor repair. If amperage returns to normal,
clear discharge and recheck.
Damaged Stator Check the stator for holes or tears. Chapter 5 – Pump End describes the pump
stator inspection procedure.
Worn Motor Bearing Remove the pump stator and hand-rotate the shaft. If the shaft turns roughly,
replace the pump. Return the failed pump to the shop and replace the motor
bearings as described in Chapter 10 – Motor Cavity.
Noisy Pump
Table 2–11
Possible Causes Troubleshooting Steps
High ow The incoming ow is greater than the pump can handle. Inltration, a sump
pump, a hot tub or any other appliance that produces excessive water ow can
cause a high ow alarm.
Plugged vent or Equal-
izer tube
Check the vent and the Equalizer tube. A plugged or partially plugged vent or
Equalizer tube will cause the alarm to activate frequently. Replace the Equalizer
tube if kinked or damaged.
Level sensor leak Remove the pump from the tank. Inspect the level sensors for cracks and debris;
use level sensor test to check for leaks.
Line blockage or worn
stator
Check the amperage. If amperage is high, look for a line blockage. If amperage
is low, inspect the stator for excessive wear.
Underground wire dam-
age
Check the tray cable wiring for cuts, breaks and shorts. Use a megohmmeter to
check for shorts between each pair of leads. Replace the tray cable if a short is
found.
