BEFORE YOU INSTALL YOUR PUMP
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,

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

WELL PIPE INSTALLATION
NOTICE: Use the installation method below which 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
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 in formation.
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 1
are recommended.
DUG WELL INSTALLATION

Same as cased well installation.
DRIVEN POINT INSTALLATION
1. Connect the suction pipe to the drive point as illustrated in 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. Flow arrow on check valve
must point toward pump.
Pump body may explode if used as a booster pump.
