INSTALLATION
PRIOR TO PUMP INSTALLATION
Prior to pump installation, follow these steps to ensure proper
installation and operations.
1. Well must not be more than 20’ depth to water.
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. Normally, pipe must 12” below frost line
and pump must be insulated.
4. Be sure all pipes and the foot valve are clean and in good shape.
5. Ensure there are no air pockets or leaks in suction pipe. Use PTEE
pipe thread sealant tape to seal pipe joints.
6. Unions installed near pump and well will aid in servicing but leave
room for using wrenches.
7. 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 the well. Add sections of pipe as needed, using
PTFE pip thread sealant tape on all male threads.
• To prevent sand and sediment from entering the system,
the foot valve/strainer should be at least 5 feet above the
bottom of the well.
• Additionally, the foot valve/strainer should be installed 10 to
20 feet below the lowest level to which water will drop while
operating (pumping water level). Your well driller can furnish
that information.
3. 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.
4. Be sure the entire run of suction pipe is leakproof so pump does
not lose prime and fail to work. Never install a suction pipe that is
smaller than the suction port of the pump.
5. When using a foot valve, a priming tee and plug are recommended
(Figure 1).

DUG WELL INSTALLATION
Use the same procedures as Cased Well installation.
DRIVEN POINT INSTALLATION
1. Connect the suction pipe to the drive point (Figure 2). Keep
horizontal pipe run as short as possible. Use PTFE pip 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 piping (Figure 2). Ensure check
valve flow arrow points toward the pump.
3. Never install a suction pipe that is smaller than the suction port of
the pump.
