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

(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.

2. To aid priming on well point installations, install a line check valve as
shown in Figure 6. Be sure check valve flow arrow points toward pump.

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.

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.
