2. Circulation and Filtration System Maintenance

Your pool's pump and filter are its heart and kidneys, working to move and clean the water. A properly functioning circulation system is essential for distributing chemicals and capturing debris.

2.1. Pump Operation and Priming

Run your pool pump for a sufficient duration each day to circulate the entire volume of water at least once—typically 8-12 hours in summer. Ensure the pump basket is clean and free of debris to maintain optimal flow. Know how to prime your pump if it loses prime, as running dry can damage the seals.

2.2. Filter Care: Backwashing, Cleaning, and Replacement

The filter type (Sand, Cartridge, or Diatomaceous Earth) dictates its care. Sand filters require backwashing when the pressure gauge rises 8-10 psi above the clean, start-up pressure. Cartridge filters need to be removed and hosed off every few weeks and soaked in a filter cleaner a few times per season. DE filters require backwashing and adding fresh DE powder. All filters need periodic deep cleaning and eventual media replacement.

2.3. Monitoring Pressure and Flow

The pressure gauge on your filter is a vital diagnostic tool. Note the "clean pressure" after a fresh backwash or cleaning. A steady rise in pressure indicates the filter is doing its job trapping debris. A very low pressure reading or poor water flow at the returns can signal a clogged pump basket, a blockage in the line, or an issue with the pump impeller.
