4. Strainer basket or skimmer basket loaded with debris. Remove the strainer housing cover or the skimmer
cover. Clean the basket, and refill the strainer housing with water. Tighten the cover.
5. Suction side clogged. Contact a qualified repair professional. You should have 5" - 6" of vacuum at the
strainer cover (your pool dealer can confirm this with a vacuum gauge). You may be able to check by
removing the skimmer basket and holding an object over the bottom port with the skimmer full and the
pump running. If no suction is felt, check for line blockage.
a. If the pump develops a vacuum, check for a blocked suction line or a dirty strainer basket. An air
leak in the suction piping may be the cause.
b. If the pump does not develop a vacuum and the pump has sufficient "priming water":
I. Re-check the strainer housing cover and all threaded connections for suction leaks. Check
if all system hose clamps are tight.
II. Check voltage to ensure that the motor is rotating at full rpm's.
III. Open the housing cover and check for clogging or obstruction in suction. Check the
impeller for debris.
IV. Remove and replace the shaft seal only if it is leaking.

Low Flow – Generally:
1. Clogged or restricted strainer or suction line. Clean skimmer strainer basket and/or pump strainer basket.
Contact a qualified repair professional.
2. Undersized pool piping. Correct the piping size.
3. Plugged or restricted discharge line of filter, valve partially closed (high gauge reading). Sand filters –
backwash as per manufacturer's instructions; D.E. filters – backwash as per manufacturer's instructions;
Cartridge filters – clean or replace the cartridge.
4. Air leak in suction (bubbles issuing from return fittings). Re-tighten the suction and discharge connections
using PTFE tape. Inspect other plumbing connections, and tighten as required.
5. Plugged, restricted, or damaged impeller. Replace the impeller including a new seal assembly.

Noisy Pump:
1. Air leak in suction piping, cavitation caused by restricted or undersized suction line or leak at any joint, low
water level in pool, and unrestricted discharge return lines. Correct the suction condition or throttle return
lines, if practical. Holding your hand over the return fitting will sometimes prove this, or by putting in a
smaller eyeball fitting.
2. Vibration due to improper mounting, etc. Mount the pump on a level surface and secure the pump to the
equipment pad.
3. Foreign matter in the pump housing. Loose stones/debris hitting the impeller could be the cause. Clean the
pump housing.
4. Motor bearings can become noisy from normal wear, rust, overheating or concentration of chemicals. If the
motor bearing seal is damaged from leaks, chlorinated water can seep into bearing washing out the grease
and could cause the motor bearing to whine. Replace the motor and any seal leaks should be repaired at
once by replacing the shaft seal.
5. Place pump closer to water level.
