INSTALLATION
PRIOR TO PUMP INSTALLATION
Ensure the well is not more than 20 foot depth to water.
Locate pump as close to the well as possible, using use as
few elbows and fittings as possible. Long runs and many
fittings increase friction and reduce flow.
Ensure the well is clear of sand. Sand will clog the pump and
void the warranty.
Protect pump and all piping from freezing. Freezing will split
pipe, damage pump and void the warranty. Check local frost
protection requirement. Usually piping must be 12" below
frost line and the pump must be insulated.
Be sure all pipes and the foot valve are clean and in good
shape.
Ensure there are no air pockets or leaks in suction pipe. Use
PTEE pipe thread sealant tape to seal pipe joints.
Unions installed near the well and pump aid in servicing.
Make sure to leave room for use of wrenches.
PUMP BODY MAY EXPLODE if used as a booster
pump. DO NOT use in a booster appli cation.
WELL PIPE INSTALLATION
Use the installation method below that matches your well type.
CASED WELL INSTALLATION
1.
Inspect foot valve to be sure it works freely. Inspect strainer
to be sure it is clean.
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 pipe thread sealant tape on male
threads. Be sure that all suction pipe is leak proof or pump
will lose prime and fail to pump.
3.
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 in formation.
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 are
recommended (Figure 1).
DUG WELL INSTALLATION
Follow the same instructions as outlined in Cased Well
Installation.

DRIVEN WELL POINT INSTALLATION
1.
Connect the suction pipe to the drive point (Figure 2). 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. Ensure the check
valve's flow arrow point toward the pump.
HORIZONTAL PIPING FROM WELL TO PUMP INSTALLATION
1.
Never install a suction pipe that is smaller than the suction
port of the pump.
2.
To aid priming with well point installations, install a check
valve as shown in Figure 2. Ensure the check valve's flow
arrow point toward the pump.

DISCHARGE PIPE SIZES
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.
