Installation

Connect system pipe to tank flange. Use plastic or
steel pipe as required. To prevent leaks, use Teflon
tape or Plasto Joint Stik

on male threads of all

threaded connections to tank.

NOTICE:

To be sure that joint is not cross threaded

and that threads are clean, always make connec
tions by hand (without sealer) first. After making
sure that threads are clean, remove pipe, add Teflon
tape or Plasto Joint Stik, and remake connection.
Tighten by hand first; finish with pipe wrench for
tight seal.

NOTICE:

When replacing a standard tank in a sub

mersible pump system, raise pump and discharge
pipe far enough to remove bleeder orifices in dis
charge pipe and plug tees. When replacing a stan
dard tank in a jet pump system, remove Air Volume
Control (AVC) and plug AVC port in pump.
In areas where the temperature is high for long
periods of time, the tank pre charge pressure may
increase. This may reduce the tank drawdown
(amount of water available per cycle). If this occurs,
reduce the pre charge pressure to two PSI below
the pump cut in setting of the pressure switch.
It is necessary to flush all air out of the piping sys
tem and water reservoir portion of the pre charged
tank. This is required on new installations, pumps
requiring repriming and pumps that have been dis
assembled for service. Do this as follows:
1. Open faucets furthest from tank and allow

pump to operate.

2. Air in the system will cause a sputtering flow;

allow faucets to run until you have a steady, air
free stream.

3. Open and close faucets repeatedly until you are

sure all air has been removed.

4. If stream does not become steady, air may be

leaking into the system; check for leaks in the
piping on the suction side of the pump.

TO CHECK TANK AIR CHARGE

If drawdown (amount of water that comes out of
tank per pump cycle) decreases significantly, check
as follows:
1. To check air charge in tank, shut off electric

power to pump, open faucet near tank, and
drain completely.

2. At the air valve in top of tank, check air pres

sure with a standard tire gauge. Air pressure
should be 2 PSI below pump pressure switch
cut in setting.

3. If the air pressure is more than 2 PSI below the

cut in setting, add air to the tank. Use an air
compressor or a portable air storage tank.

4. Use soap or liquid detergent to check for air

leaks around air valve. Continuous bubbling
indicates a leak. If necessary, install new core in
air valve. This is the same as those used for
automobile tubeless tires.

TO CHECK PUMP PRESSURE

SWITCH SETTING

1. To check pressure switch setting, disconnect

power to pump at supply panel (but be sure to
leave pressure switch connected to power sup
ply wires).

2. Remove pressure switch cover.
3. Open a faucet near tank.
4. Bleed pressure down until pressure switch con

tacts close; immediately close faucet.

5. Check pressure at valve with standard tire

gauge or with pump pressure gauge (if sup
plied).

6. Pressure gauge should read 2 PSI below pump

cut in setting (28 PSI for 30 50 switch, 18 PSI
for 20 40 switch, etc.) If not:
A. Adjust switch according to switch manufac

turer’s instructions.
