Pool pump maintenance checklist
Updated August 2026
A pool pump asks for little: empty the strainer basket every week and never let it run dry. Keep the lid O-ring greased and the union seals tight, run a variable-speed pump 8 to 12 hours on its schedule, and the motor reaches its 8 to 12 year life. Let the basket clog or the water drop below the skimmer and the pump loses prime, runs dry, and cooks the shaft seal and motor in minutes.

What neglect costs
Running dry is what kills pumps. Starve the pump of water, whether from a clogged basket, a level that fell below the skimmer, or an air leak on the suction side, and the shaft seal overheats in minutes, melts, and lets water into the motor, which then cooks. A dry-run can also warp the plastic housing outright. A replacement motor runs $150–350 and a whole new pump $300–800 installed, against a weekly basket clean and a level check that cost nothing.
Leave these to a pro
Most of this is homeowner work with a screwdriver and a tube of O-ring lube. Bring in a pro when the motor screeches from failing bearings, when the seal needs replacing and the wet end has to come apart, or for any electrical fault at the timer or breaker. A pump-rebuild or motor swap done right, with the seal and impeller matched to the housing, runs $100–200 in labor plus parts. A yearly service is a good baseline if you would rather not open the housing yourself.

Why is my pool pump losing prime or sucking air?
Air in the basket means the suction side is drawing air instead of water. The usual culprits are a low water level that lets the skimmer gulp air, a dry or cracked lid O-ring, a loose pump lid, or a leaking union or valve on the intake line. Top off the water, clean and grease the O-ring, and hand-tighten the lid first. Persistent bubbles after that point to a leak in the suction plumbing that needs tracing back toward the skimmer.
How many hours a day should the pump run?
Enough to turn the whole pool over once, generally 8 to 12 hours a day in season. A single-speed pump usually gets there in about 8 hours of run time. A variable-speed pump can run longer at a low, efficient speed and still cost far less to operate, while filtering more gently and quietly. Splitting the runtime into two blocks, morning and evening, keeps chlorine spread evenly. In winter or a closed pool, the schedule drops way down or off.
Why is my pump loud or screeching?
A high-pitched squeal or grinding almost always means the motor bearings are wearing out, often after water from a failed shaft seal worked its way in. Once bearings go, the motor is on borrowed time and usually gets replaced rather than rebuilt. A low growl or rattling, by contrast, can just be a vibrating pump pad or debris in the impeller. Catching a leaking seal early, before it reaches the bearings, is what saves the motor.
How do I winterize the pump?
In any freeze climate, water left inside the pump can freeze, expand, and crack the housing, so the pump has to be drained as part of closing. Cut the power, remove the drain plugs from the pump and filter, and let everything empty completely, then store the plugs in the basket so you find them in spring. Blowing out the plumbing lines back to the pump finishes the job. The full winterizing routine covers the rest of the equipment pad.
