WELL PIPE INSTALLATION
Use the installa
tion methods provided in this chapter that match with your water source.
CASED WELL/DUG WELL INSTALLATION
1. Inspect the
foot or in line check valve to be sure it works
freely. Inspect the strainer to be sure it is clean and
secure.
2. If using a foot valve, connect the foot valve and strainer to
the first length of suction pipe and lower the pipe into the
well. Add sections of pipe as needed, using Teflon tape on
the male threads. Use 2 in. pipe for suction pipe. Be
sure all suction pipe is leak proof or the pump will lose
prime and fail to pump. Install foot valve 10 to 20 ft. (3 to 6
m) below the lowest level to which water will drop while
the pump is operating (pumping water level). Your well
driller can furnish this information.
3. To prevent sand and sediment from entering the pumping
system, a foot valve/strainer should be at least 5 ft. (1.5 m)
above the bottom of the well.
4. When proper depth is reached, install a sanitary well seal
over the pipe and in the well casing. Tighten bolts to the
seal casing.
5. When using a foot valve, a priming tee and plug are
recommended.

NOTICE: It is recommend that pump be installed in well ventilated enclosure.
DRIVEN P
OINT INSTALLATION
1. Connect suctio
n pipe to the drive point. Keep the horizontal
pipe run as short as possible. Use Teflon tape on male pipe
threads. Multiple well points may be necessary to provide
sufficient water to the pump.
2. Install a check valve in the horizontal pipe. The flow arrow
on the check valve must point toward the pump.
