DRAINING FOR SERVICING OR FOR WINTER

The system should be drained before it is disconnected for servicing, or if it is inoperative for an extended
period of time, or if it is in danger of freezing. To Drain:
• Follow the instructions in your pump installation manual to drain the pump.
• Open tank drain cock to drain tank.
• Drain all piping to a point 3 feet below ground level.

DIAPHRAGM TANK INSTALLATION

Diaphragm tanks are recommended for clear water applications. Vertical tanks are the most commonly
used tanks. However, horizontal tanks and in-line tanks may be used where space is more critical. See
Tank Specifications for tank capacity.

General Materials

• One can PVC cement (read instructions carefully) • One can thread compound (read instructions carefully)
• One 1 in. gate valve • One 1/2 in. relief valve • Enough rigid 1 in. PVC pipe and couplings to reach from
pump to pressure tank to service line • One male 1 in. PVC adapter • One 1 in. X 11 in. tank cross or
1 1/4 in. X 13 in. depending on acceptance fitting, see Chart 1 • Two 3/8 in. plugs • One 1/2 in. boiler
drain • One 1/2 in. street tee
REMINDER: All joints and connections must be airtight. A single pin-hole leak will prevent the proper operation of
the system. Use thread compound on all threaded connections unless specified otherwise.

TYPICAL JET PUMP INSTALLATION

STEP 1
Complete pump assembly and electrical connections
as specified in pump installation manual. Place tank
in desired location and level it.
STEP 2
Thread tank tee into pressure tank so that the two
3/8 in. holes in the tee face upward. Thread street
tee into front of tank tee. See Figure 1.

STEP 3
Thread 3/4 in. male PVC adapter into the inlet side
of tank tee. See Figure 2.

STEP 4
Thread pressure relief valve into top of street
tee. Thread the 1/2 in. boiler drain into front of
street tee. Cut and cement as many sections and
couplings of PVC pipe needed to connect 3/4 in. male
PVC adapter to pump discharge. See Figure 3.
