Installation 5
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tape

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 5
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6.

necessary to provide sufficient water to pump.
2. Install a check valve in horizontal pipe. Flow arrow on check valve
must point toward pump.

2. To aid priming on well point installations, install a line check valve as

Discharge Pipe Sizes
1. If increasing discharge pipe size, install reducer in pump discharge port.
Do not increase pipe size by stages.
2. When the pump is set away from the points of water use, the discharge
pipe size should be increased to reduce pressure losses caused
byfriction.

Sprinkling Application
This pump is de signed to deliver plenty of water at full sprinkler pres sure. It can
pump from a pond, cistern or well points.
Pump discharge can be divided to supply two (2) or more sprinkler systems.
A suggested multiple dis charge to service is shown in Figure 7.
Do not use in a pressure tank or booster pump application.
