Shallow Well Application Only
1. Begin the connection to the pressure tank. Using a 3/4 in. x 3 in. galvanized nipple,
wrap the threads 5 times with pipe tape and apply pipe paste (pipe dope) and install in
top of pump (Fig. 1).
2. Install a 3/4 x 3/4 x 3/4 in. galvanized tee fitting (Fig. 2).
3. Install a 3/4 in. MPT x 1/4 in. FPT galvanized bushing and pressure gauge (optional), or a
pipe plug. Do not tighten, as you will prime your pump later at this location (Fig. 3).
4. Continue with fittings and pipe to the pressure tank. A 3/4 in. union (optional) for easy
connection and disconnection (Fig. 4).

Deep Well Application Only
1. To begin the connection to the pressure tank, loosely assemble flow control body to pump
head. Using Teflon tape, position the discharge outlet of the control body facing right as
you look directly into the face of the pump (Fig. 1).
2. Assemble the pressure switch in the 1/4” tapping adjacent and to the right of the discharge
outlet of the control valve (Fig. 2). Refer to Pump Electrical Connection section for
pressure switch wiring.
3. Tighten flow control body
(Fig. 3).
4. Install optional pressure gauge in 1/4” tapping on side of pump body. Face of gauge
should be positioned so that dial can be read easily (Fig. 4).
5. Continue with fittings and pipe to the pressure tank. A 3/4 in. union is optional but
recommended for easy connection and disconnection (Fig. 5).
CAUTION: Install a pressure relief valve on any installation where the pump pressure can
exceed the maximum working pressure of the tank.
