TESTING FOR BLADDER
LEAKAGE
Step 1. Disconnect power to pump.
Step 2. Drain water from tank bladder by opening
faucet closest to tank.
Step 3. Remove valve cap and release all pressure
by depressing valve core. When air stops
coming from valve, remove valve core to
release remaining pressure.
Step 4. Disconnect piping from elbow on tank
cover flange.
Step 5. Carefully turn tank upside down or lay on
its side.
Retained water in tank may
cause sudden weight shift when lowering. Support
tank so it cannot fall when being lowered or
inverted.
Step 6. If bladder leaks, water will run out of valve.
If so, replace bladder.
Step 7. If replacing bladder, be sure air and water
pressures are relieved before removing
cover flange. When reassembling cover
flange, do not tighten nuts or mounting
studs more than 85 in-lbs. (9.6 Nm).
NOTICE: When using metal pipe with plastic fit-
tings use only Teflon tape or Plasto-Joint Stik
1
on
male threads.
NOTICE: Most standard tanks have separate inlet
and outlet ports. Pre-charge tanks have one port
serving both functions. When replacing standard
tank with a pre-charge tank, run pipe from pump
into a tee as shown. 2nd leg of tee goes to tank
elbow; 3rd leg goes to existing service.
