3. Foreign matter in pump housing. Loose stones/debris hitting impeller will cause noise.
Solution: With the pump turned off or disconnected from the power source clean the pump housing and in-
spect to remove any debris visible in the inner portion of the pump by the impeller.
4. Motor bearings noisy from normal wear, rust, overheating, or concentration of chemicals causing seal dam-
age. This will allow chlorinated water to seep into bearings wiping out the grease resulting in rusting of the
motor shaft and causing the bearing to whine.
Solution: All seal leaks must be replaced at once. Have a qualified pump repair specialist replace the motor
shaft seals and inspect the motor shaft for possible damage. If the motor shaft is damaged replace the motor.
WATER LEAKS AROUND INTAKE AND DISCHARGE FITTINGS – CHECK FOR
1. Lose union fittings or hose fittings.
Solution: Tighten fittings or remove, apply Teflon tape and reinstall.
2. Lose hose clamps on flexible hose.
Solution: Tighten hose clamps using a nut driver or wrench instead of a screwdriver
3. Leaks that continue after trying the above solutions.
Solution: Inspect union fittings and hose fittings for excess plastic mold flashing that can cause hoses and
plumbing not to seal. If plastic mold flashing is found remove it with a fine tooth file or knife blade and re-as-
semble. If the fitting still will not seal replace them and reassemble plumbing with the new fittings.
