Installation
3. To prevent sand and sediment from entering
pumping system, foot valve/strainer should be at
least 5 ft. (1.5 m) above bottom of well.
4. When proper depth is reached, install sanitary well
seal over pipe and in well casing. Tighten bolts to
seal casing.
5. When using foot valve, a priming tee and plug are
recommended. (Figure 1).
Driven Point Installation
1. Connect suction pipe to drive point (Figure 2). Keep
horizontal pipe run as short as possible. Use PTFE
tape on male pipe threads. Multiple well points will
most likely be necessary to provide sufficient water
to pump.

2. Install check valve in horizontal pipe. Flow arrow on
check valve must point toward pump.

Horizontal Piping from Well to Pump
1. Do not reduce suction pipe to less than 1-1/2".
2. Install in-line check valve (see Figure 2). Be sure
check valve flow arrow points toward pump.
Discharge Pipe Sizes
Discharge pipe size should be increased to reduce
pressure losses caused by friction on long pipe runs.
•
Up to 100' (30.5 m) run: Same size as pump
discharge port.
•
100' - 300' (30.5 - 91.4 m) run: Increase one
pipe size.
•
300' - 600' (91.4 - 182.9 m) run: Increase two
pipe sizes.
•
Do not reduce to garden hose size.
NOTICE Use only PTFE tape or PTFE-based joint
compounds for making all threaded connections to
the pump itself. Do not use pipe joint compounds on
plastic pumps: they can react with the plastic in pump
components. 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. Install pump as close to well head as possible. Long
piping runs and many fittings create friction and
reduce flow.
2. Bolt pump to solid, level foundation.
3. Support all piping connected to pump.
4. Wrap 1-1/2 to 2 layers of PTFE tape clockwise (as
you face end of pipe) on all male threads being
attached to pump.
5. Tighten joints hand tight plus 1-1/2 turns. Do
not overtighten.
6. Replace prime plug with pressure gauge. This will
aid in sizing zones, troubleshooting, and following
pump performance chart.
NOTICE For long horizontal pipe runs or when using a
foot valve, install a priming tee between check valve and
well head (Figure 1). For driven point installations, install
check valve. Be sure that check valve flow arrow points
toward pump.
