SELECTION

WARNING: Turn off power at the electrical

service box before starting installation.
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 Performance chart on page 5 to be sure

pump is rated for this depth.

(Fig. 1)

NOTE: Schedule 80 PVC pipe (sold separately) is recommended. If you use black poly pipe (sold separately),

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 (not included) applied, tightened

securely with a pipe wrench (not included) and then tightened an additional 1/4 turn.

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 at least 10 feet from the top of the well

screen.

(Fig. 2)

CAUTION: If your pump depth is 200 ft.

or more, you may want to consider contacting

a professional well pump installer. Piping

filled with water, along with the weight of

the pump, will be very heavy. Be sure to have

assistance during pump installation.

ASSEMBLY INSTRUCTIONS

Follow step 1a and 1b below for Schedule 80 pipe

or step 2a and 2b for black poly pipe.

Schedule 80 pipe (recommended)
1a. Apply thread tape and then thread the pipe

directly into the pump discharge and tighten.

For 1 in. pipe, you will also need a 1-1/4 in. x 1

in. reducer bushing, not shown.

1b. Slide the two hose clamps packaged with the

torque arrestor over the end of a short piece of

Schedule 80 pipe (approximately 4 ft. long).

The pump will be easier to handle if a short

piece is installed first. Continue to Step 3.
