INSTALLATION
Refer to the following text and fi gures to install your pump:
• Do not install pump more than 20 feet above the surface
of the water.
• Use as few elbows and fi ttings as possible to reduce friction
and maximize fl ow.
• Be sure pipe, fi ttings, and foot valve
are clean and free of debris.
• Ensure there are no air pockets or leaks
in the suction pipe.
• Use Tefl on tape to seal threaded pipe
connections.
• Wrap all threaded male pipe ends
and fi ttings with Tefl on tape. This will
ensure a good seal around all pipe
connections.
• Use PVC pipe primer on all glue
joints before applying PVC cement.
After applying PVC cement to both surfaces to be glued,
connect pipe and fi tting, turn pipe one-quarter turn,
and hold for 30 seconds. This will ensure a positive
cementing of all joints.
The following are three well and water source applications
for the LS sprinkler pump. Wells may differ slightly but the
application is essentially the same.
Application 1: Single Shallow Well
A single shallow well 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 20' in depth.
Connect the foot valve to the fi rst 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 fi ve 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.

Application 2: Multi-Point Shallow Well
The multi-point shallow well confi guration consists of two
or more wells as a water supply. The wells should be at least
fi ve feet apart. The wells may be spaced as a straight line
(two or more wells), a triangle (three wells), or a square (four
wells).
Install a check valve or a fi ne screen well point on each well
to ensure the pump maintains prime. The fl ow arrow on a
check valve must point toward the pump.
Application 3: Lake Or Pond Installation
Using a surface water source such as a lake or pond is
similar to using a single shallow well. The suction pipe is
placed in the water source and leads back to the pump. This
application may require a long horizontal distance between
water source and pump.
The suction pipe size should increase by one size to minimize
pressure loss caused by friction from pipe distance.
Place a foot valve at the end of the suction pipe to protect the
pump from debris.
