# Pool pump

The pool pump moves water through the filter, heater, and chlorine system, and back to the pool.

The pump is the heart of your pool. If it stops, the water stops moving, chlorine does not spread, and the filter does not work. Algae can start within a day or two in hot weather.

Signs of trouble include loud grinding, humming with no start, leaks at the front, low flow, or a basket that stays empty. Check [baskets](https://marinapool.multisites.ai/glossary/pump-basket) and the [lid O-ring](https://marinapool.multisites.ai/glossary/lid-o-ring) first. For electrical faults or motor problems, call a pro. Marina Pool Services repairs pool pumps.
