The pump is the heart of your pool. It pulls water from the skimmers and main drain, pushes it through the filter and heater, and returns it to the pool. When the pump starts to fail, water quality drops quickly, especially during a Glendale summer.
Most pumps give warning signs before they stop completely. Catching those signs early often means a smaller, simpler repair.
Loud or Unusual Noises
A healthy pump runs with a steady hum. Grinding, screeching, or rattling sounds usually point to worn motor bearings or debris inside the pump. A loud gurgling or rumbling can mean the pump is pulling air or not getting enough water. Noise problems tend to get worse over time, so they are worth checking early.
Leaks Around the Pump
Water dripping from beneath the motor often means the shaft seal is wearing out. Leaks around the lid or unions may come from worn O rings. Small leaks are usually inexpensive to fix, but water reaching the motor can damage it and lead to a much bigger repair.
Trouble Priming or Losing Prime
If the pump basket never fills with water, or the pump runs with lots of air bubbles, it may be losing prime. Common causes include a low water level, a clogged skimmer or pump basket, a loose lid, or an air leak on the suction side. Running a pump dry generates heat that can damage seals and parts.
The Motor Hums but Will Not Start
A humming pump that does not spin up may have a failed start capacitor, a seized motor, or debris jamming the impeller. Repeatedly trying to start a stuck pump can burn out the motor, so it is best to turn it off and have it checked.
Tripped Breakers or Overheating
A pump that trips the breaker, shuts off on its own, or feels very hot to the touch has an electrical or mechanical problem that needs attention. These issues should be handled by someone who works with pool equipment regularly.
Weak Flow and Cloudy Water
If the return jets feel weak and the water is not as clear as usual, the pump may not be moving enough water. A clogged impeller, dirty filter, or blocked line can cause the same symptom, so it helps to check the baskets and filter pressure first. Glendale's seasonal winds often clog baskets and impellers with leaves.
Repair, Replace, or Upgrade
Many pump problems can be repaired with new seals, bearings, or capacitors. If the pump is old or the motor has failed, replacing it with a variable speed pump is often worth considering, since these pumps adjust speed and generally use less energy than single speed models. Our pool pump repair page explains the options. For sudden failures, see emergency pool repair, and for a full check of your system, book a pool equipment inspection. Contact Glendale Pool Service if your pump is showing any of these signs.
