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,

damage pump and void the warranty. Check locally for frost protection

requirements (usually pipe must be 12” below frost line and pump must

be insulated).

4. Be sure all pipes and foot valve are clean and in good shape.

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

use wrenches.

8.

Pump body may explode if used as a booster pump.

DO NOT use in a booster application.

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 information.

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 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 pipe. Flow arrow on check valve

must point toward pump.
