Professional local pool care
Help the circulation system move and clean water efficiently
The filter captures material that circulation carries out of the pool. As debris accumulates, pressure and flow can change. A dirty or damaged filter can contribute to weak circulation, cloudy water, longer run time, and difficulty recovering after storms or algae treatment.
Cartridge, sand, and diatomaceous earth filters are serviced differently. The correct procedure depends on the equipment model, pressure history, condition of internal parts, and whether the filter is being cleaned as routine maintenance or during a water-quality problem.
We review the filter as part of the overall circulation system. Repeatedly rapid pressure increases may point to heavy debris, algae, undersized equipment, damaged media, or another condition that cleaning alone will not solve.
What we review
- Cartridge removal, inspection, and cleaning
- Sand-filter backwash and performance review
- DE filter service and recharge considerations
- Pressure-gauge and flow observations
- Recommendations when elements, grids, valves, or seals appear damaged

Common pool-service questions
How often should a pool filter be cleaned?
Frequency depends on filter type, manufacturer guidance, pressure increase, pool use, landscaping, weather, and water condition. Pressure trends are usually more useful than a fixed calendar alone.
Can a dirty filter make pool water cloudy?
Yes. Reduced flow or overloaded media can limit filtration, but cloudy water can also involve chemistry, algae, circulation, or equipment problems.
