Single Shallow Well (Figure 4)
The single shallow well (Figure 4) is
typically a drilled well with a 4" or 6"
steel or plastic casing running vertically
into the ground. The surface of the water
should not exceed 25 feet in depth.
Connect the foot valve to the first length
of suction pipe and lower into well.
Add pipe sections as needed, securing
them using one of the sealing methods
previously mentioned. The foot valve
should be AT LEAST 5 feet below the
surface of the water to allow for water
draw down. Seal the top of the 4" or 6"
well casing with a well seal to prevent debris from falling into the well.
A. Suction Port Connection (Figure 5)
1. Attach the foot valve or well point to pipe assembly and lower pipe
and foot valve until it is at least five feet below the water level.
If you are using a well, temporarily clamp the pipe to the well casing
to prevent the pipe from sliding into the well. If well is in a 4" or 6"
casing, use a well seal at the surface. Never use a suction pipe size
smaller than the size of the suction port on the pump.
2. Connect the necessary elbows, fittings, check valves, and pipe from
the water to the pump suction port on front of pump. When using
PVC, pre-assemble pipe and fittings to the pump BEFORE applying PVC
cement to ensure proper cuts and inventory. Use PTFE tape on all male
threads, wrapping clockwise (when facing pipe) 1 to 2 layers thick.
Tighten all threaded pipe fittings until snug. DO NOT OVER-TIGHTEN PIPE
AND FITTINGS. Tighten joints hand-tight plus 1/2 turn with pipe wrench.
B. Discharge Port Connections (Figure 6)
1. Thread male adapter or pipe nipple into discharge port on top
of pump. (Use PTFE tape on thread.)
2. Connect pipe between the sprinkler manifold and the pump
discharge. Discharge pipe size should increase with long pipe runs.
Discharge pipe size may equal discharge port size for distances up to
100'. Increase discharge pipe size by one size for distances of 100' to
300'. For 300' to 600', increase pipe size by two sizes. This will reduce
pressure loss caused by friction.
3. Tighten all threaded pipe connections with pipe wrench until snug.
Do not over-tighten.
