NOTICE: Well must not be more than 20’ depth to water.
1. Long runs and many fittings increase friction and reduce flow. Locate
pump as close to well as possible: use as few elbows and fittings
as possible.
2. Be sure well is clear of sand. Sand will plug the pump and void
the warranty.
3. Protect pump and all piping from freezing. Freezing will split pipe,
damage pump and void the warranty. Check locally for frost protection
requirements (usually pipe must be 12” below frost line and pump must
be insulated).
4. Be sure all pipes and foot valve are clean and in good shape.
5. No air pockets in suction pipe.
6. No leaks in suction pipe. Use PTFE pipe thread sealant tape to seal
pipe joints.
7. Unions installed near pump and well will aid in servicing. Leave room
to use wrenches.
8.
Risk of explosion. Pump body may explode if used as a
booster pump. DO NOT use in a booster appli­cation.
NOTICE: Use the installation method which matches your well type.
9. Install a check valve in the pump suction port. Be sure that the flow
arrow points toward the pump. Failure to install a check valve on the
inlet side of the pump may allow the pump body to drain between
pump cycles, causing dry running, seal or internal failure, and voiding
the warranty.
Use PTFE pipe thread sealant tape or pipe joint
compound approved for use on PVC.

2. Connect foot valve and strainer to the first length of suction pipe and
lower pipe into well. Add sections of pipe as needed, using PTFE tape
on male threads. Be sure that all suction pipe is leakproof or pump
will lose prime and fail to pump. Install foot valve 10 to 20 feet below
the lowest level to which water will drop while pump is operating
(pumping water level). Your well driller can furnish this in­formation.
3. To prevent sand and sediment from entering the pumping system, the
foot valve/strainer should be at least 5 feet above the bottom of the well.
4. When the proper depth is reached, install a sanitary well seal over the
pipe and in the well casing. Tighten the bolts to seal the casing.
5. When using a foot valve, a priming tee and plug as shown in Figure 5
are recommended.

Driven Point Installation
1. Connect the suction pipe to the drive point as illustrated in Figure 6.
Keep horizontal pipe run as short as possible. Use PTFE pipe thread
sealant tape on male pipe threads. Multiple well points may be
necessary to provide sufficient water to pump.
2. Install a check valve in horizontal pipe. Flow arrow on check valve
must point toward pump.

1. If increasing discharge pipe size, install reducer in pump discharge port.
Do not increase pipe size by stages.
2. When the pump is set away from the points of water use, the discharge
pipe size should be increased to reduce pressure losses caused
by friction.
• Up to 100’ run: Same size as pump discharge port.
• 100’ to 300’ run: Increase one pipe size.
• 300’ to 600’ run: Increase two pipe sizes.
Sprinkling Application
This pump is de­signed to deliver plenty of water at full sprinkler pres­sure. It can
pump from a pond, cistern or well points.
Pump discharge can be divided to supply two (2) or more sprinkler systems.
A suggested multiple dis­charge to service is shown in Figure 7.
Do not use in a pressure tank or booster pump application.

Make sure that all pipe joints in the suction pipe are air tight as well as
water tight. If the suction pipe can suck air, the pump will not be able to
pull water from the well.
1 Bolt pump to solid, level foundation.
2. Support all piping connected to the pump.
3. Wrap 1-1/2 to two layers of PTFE tape clockwise (as you face end of
pipe) on all male threads being attached to pump.
4. Tighten joints hand tight plus 1-1/2 turns. Do not overtighten.
NOTICE : Install pump as close to well head as poss­ible. Long piping runs
and many fittings create friction and reduce flow.
NOTICE: For long horizontal pipe runs, install a priming tee between check
valve and well head as shown in Figure 6. For driven point installations,
install a check valve as shown in Figure 6. Be sure check valve flow arrow
points toward pump.
Use schedule 80 or iron pipe. See Well Pipe In­stalla­tion for more

Figure 14 – Fill Pump Before Starting
Figure 15 – Do Not Run Pump with
Discharge Shut-off.
1117 0993
NOTICE: The term ‘priming’ refers to the process of pumping all the air
out of the system, filling the pump and suction piping with water, and
beginning to move water through the pump and out into the system. A ‘selfpriming’ pump generally will repeat this process without attention once
the pump and system are full of water. If the water drains out of the pump
(back into the well, for example), then the whole priming process must be
repeated before operating the pump again.
To make sure that the pump will ‘retain its prime’ (that is, that the pump
and its piping will stay full of water), BE SURE to install a check valve in the
pump inlet port with the flow arrow pointing towards the pump. The check
valve will prevent water from siphoning out of the pump body and back
down into the well, which will keep the pump full and allow it to restart on
its own.
DO NOT remove the recirculation valve cover (there are spring-loaded
parts inside the recirculation valve – see Figure 16) when priming or
draining the pump. The drain is a hex-head pipe plug underneath the pump
body. To drain the pump, remove the hex plug (Ref. No. 17, Repair Parts
diagram). Do not disturb the recirculation valve (Ref. No. 19).
• If the pump or the suction pipe have been drained for any reason,
BE SURE to reprime the pump before starting it.
NOTICE: NEVER run the pump dry. Running the pump with­out water in it
will damage the seals, can melt the impellers and diffusers, and voids the
warranty. To prevent damage, fill the pump with water before starting.
1. Remove priming plug (Figure 13).
2. Make sure suction and discharge valves and any hoses on discharge
side of pump are open.
3. Fill pump and suction pipe with water.
4. Replace priming plug, using PTFE tape on thread; tighten plug.
NOTICE: If a priming tee and plug have been provided for a long
horizontal run, be sure to fill suction pipe through this tee and replace
plug. (Don’t forget to PTFE tape the plug.)
5. Start pump: water should be produced in 5 minutes or less, the
time depending on depth to water (not more than 20’) and length of
horizontal run (10’ of horizontal suction pipe = 1’ of vertical lift due to
friction losses in the pipe).
If no water is produced within 5 minutes, stop pump, release all
pressure, remove priming plug, refill and try again.
Hazardous pressure and risk of ex­plo­­sion and scalding. If pump
is run con­ti­nu­ously at no flow (that is, with discharge shut off or without
priming), water may boil in pump and piping system. Under steam pressure,
pipes may rupture, blow off of fittings or blow out of pump ports and scald
anyone near.
To prevent explosion, do the following:
A. Be sure discharge (valve, pistol grip hose nozzle, etc.) is open whenever
pump is running.
B. If pump fails to produce water when attempting to prime, release
all pressure, drain pump and refill with cold water after every
two attempts.
C. When priming, monitor pump and piping tempera­ture. If pump or
piping begin to feel warm to the touch, shut off pump and allow system
to cool off. Release all pressure in system and refill pump and piping
with cold water.
