Finding the Depth of Your Well:
1. Tie a small, heavy weight to the end of a cord
(make sure the cord is at least 350 ft. long). Lower
this weight into the well until it reaches the bottom.
Take up any slack and mark the string at ground
level. Pull the string from the well and measure
from the weight to your mark. This is the depth of
your well. Subtract 10 ft. from your well depth. See
catalog erformance charts to be sure pump is rated
for this depth. (Fig. 1)
2. Drawdown is the lowest water level in the well
after the pump is turned on. If you know the
drawdown, the pump can be set 20 feet below this
level. However, the bottom of the motor should be
a at least ten feet from the top of the well screen.

ASSEMBLY
NOTE: Schedule 80 PVC pipe is recommended. If you use black poly pipe, the pipe must be rated for 160 PSI
and be no longer than 200 ft.
NOTE: The pump must be assembled with piping on the ground before lowering into the well. Lay out all
necessary materials near the well.
NOTE: All threaded joints and connections should have thread tape applied, tightened securely with a pipe
wrench and then tightened an additional 1/4 turn.
