PLUMBING
Bolt the pump to a level, solid foundation. Position the pump
with the suction port facing the water source pipe(s). Avoid 90º
angles whenever possible and minimize turns when connecting
pump to your water source. Install the pump as close to the
water source as possible. This will help reduce friction and
maximize water pressure.
A. Suction Port Connection
Step 1:
Attach the foot valve or well point to the pipe assembly and
lower pipe and foot valve until it is at least fi ve 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 the 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.
Step 2:
Connect the necessary elbows, fi ttings, check valves,
and pipe from the water to the pump suction port on the
front of the pump. When using PVC, pre-assemble pipe
and fi ttings to the pump BEFORE applying PVC cement to
ensure proper cuts and inventory. Use tefl on tape on all
male threads, wrapping clockwise (when facing pipe) 1 to
2 layers thick. Tighten all threaded pipe fi ttings until snug.
NOTICE: DO NOT OVER-TIGHTEN PIPE AND FITTINGS!! Tighten
joints hand-tight plus 1/2 turn with a pipe wrench.

B. Discharge Port Connections
Step 1:
Thread the male adapter or pipe nipple into the discharge port
on top of the pump. Use tefl on tape on threads.
Step 2:
Connect the pipe leading to the sprinkler manifold to the
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.
Step 3:
Tighten all threaded pipe connections with a pipe wrench until
snug. Do not over-tighten.
