The water pump will not shut-off/runs when the faucet is closed:
• The fresh water tank fill valve is completely closed.
• Check output side (pressure) plumbing for leaks and inspect for a leaky toilet
or valves.
• Look for loose drive assembly or pump head screws.
• Are the valves or the internal check valve held open by debris or is the rubber
swollen?
The water pump is noisy or rough in operation:
• Check for plumbing which may have vibrated loose.
• Does the mounting surface multiply noise (flexible)?
• Check for mounting feet that are loose or compressed too tight.
• Look for loose pump head to motor screws. (Three long screws.)
• Is the motor with the pump head removed? Is noise coming from the motor or
pump head?
The water pump is rapid cycling:
•Look for restrictive plumbing/flow restrictors in the faucets or shower heads.

The pressure accumulator tank is mounted in the water bay near the
water pump. The accumulator tank will need to have maintenance
checks completed bi-monthly. The accumulator features:
1. Smooth flow from the faucets.
2. Reduced water pump cycling.
3. A precharged air cushion.
4. Elimination of pulsations and water hammer.
5. Pressure of water at faucets.
The accumulator tank has a tire valve for checking the air pressure
in the tank. The precharged pressure must not exceed the water pump
cut-in pressure, the pressure at which the pump restarts. The shur flow
water pump has a cut-in pressure at 25 psi. Air pressure in the accumu-
lator tank should be set at 18 to 22 psi, and should not exceed 25 psi. To
check the air pressure in the accumulator tank, ensure the water pump is
off and water pressure is relieved. You can open a faucet to relieve the
water pressure or open the fill water fill valve to relieve the pressure.
Using a tire air pressure gauge, one which reads low air pressure,
Check the accumulator tank pressure bi-monthly. In the event you need
to add air pressure to the accumulator tank, a manual pump is
recommended. Compressed air flow can overcharge the tank too
quickly causing the tank to rupture.
