Lake
Installation (Figure 3)
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.
1-1/2" PVC
The suction pipe size should increase by one size to
ELBOW
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.

PLUMBING
Bolt the pump to a level, solid foundation, if possible.
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.

HORIZONTAL OFFSET SUCTION PIPING
When the pump is offset from the well, the horizontal
offset suction piping may have to be increased in
diameter to reduce friction loss. The friction loss in a
system increases:
1. As the flow rate increases
2. As the piping size decreases
Consult included Turf Boss performance tables
(Appendix III) and friction loss tables (Appendix IV)
to determine the amount of head lost for a given
application. Pipes from the well to the pump should
slope upward (about 1" of rise for every 30" of run).
DISCHARGE PIPE SIZES FOR
INSTALLATION
When the pump is located at a distance from points of
Or Pond
water use, it is necessary to increase the discharge pipe
size in order to reduce friction loss. The friction loss in a
system increases:
1. As the flow rate increases
2. As the piping size decreases
Consult included Turf Boss performance tables
(Appendix III) and friction loss tables (Appendix IV)
to determine the amount of head lost for a
given application.
A. Suction Port Connection (Figure 4)
Step 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.
Step 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.
