be required:

• PVC cement (if plastic pipe is used)

• Teflon tape

• Pipe, pipe couplings and fittings

• 1” nipple (for discharge)

• 1” tee or 90° elbow (for discharge)
* 1” pipe plug if tee is used

• 1-1/4” foot valve (for cased wells)

• 1-1/4” check valve (for driven wells)

• Single pipe well seal for 1-1/4” pipe (cased or

dug wells)

• Copper electrical wire (See Wiring in Electrical)

Assembly (Continued)

2. Screw in pressure switch to 1/4” tapping on side
of pump hand tight. Tighten pressure switch with
wrench.

3. Use Teflon tape or pipe joint compound for
making all threaded connections to the pump.

4. Assemble 3/4” pipe to discharge port of pump.
Assemble suction pipe with union to front
of pump. Unions installed near pump and
well will aid in servicing. Leave room to use
wrenches.Tighten joints to approximately 140 ft.
lbs.

5. Bolt pump to solid, level foundation. Support all

piping connected to the pump.

2. Screw elbow fitting to discharge tee. Push flexible
hose onto elbow. Tighten clamp with screwdriver.

3. Connect service line to tank Tee.

4. NOTE: DO NOT install a check valve between

pump and pressure tank. This will cause the
pressure switch to malfunction.

IMPORTANT: Your pump pressure switch is set for

a 20-40 PSI (1.4 - 2.8 Kg/cm2) range and requires
a tank pre-charge of 18 PSI for proper operation
(See Figure 7.)

Checking Tank Pre-Charge

Failure to ground motor

can cause severe or fatal
electrical shock hazard

Do not ground to a gas

supply line.

To avoid dangerous or fatal

electrical shock, turn off
power to motor before
working on electrical
connections.
