Pipe leaking.

Insure all threads have 3 wraps of

Teflon tape + hand tight + 1/2 turn with

wrench.

See FIG 3 to check and add air

pressure to the tank.

Air in the system.

Insure all threads have 3 wraps of

teflon tape + hand tight + 1/2 turn with

MAINTENANCE REqUIREMENTS
• Pressure Tank Charge – should be checked

every 3 months to confirm tank air pressure. See

FIG 3 for description to check air pressure.
Note – tank pressure should be set

approximately 5 psi higher than the expected

incoming pressure.

• Internal Check Valve – if Teflon tape or debris

enters into the pump cavity, the operation of the

internal check valve can be restricted. This may

create an erratic or poor performance with the

pump. To clean the check valve see FIG 4.

FIG 4 – INTERNAL CHECK vALvE

a. Remove the air relief

port and top cover

b. Confirm the spring

and check valve are

free of debris
