Pool Filter Cleaning & Replacement
Keep your water crystal clear with professional filter service and expert replacements.
Your Filter Does the Heavy Lifting
Your pool filter is the hardest-working piece of equipment you own. It runs for hours every day, trapping dirt, debris, oils, and microscopic particles that make water cloudy. When your filter gets clogged or worn out, your entire pool suffers. Water turns murky, chemicals do not work properly, and you end up fighting constant algae and balance problems.
Regular filter cleaning keeps your pool running smoothly and your water sparkling. In Castro Valley, where pollen, dust, and leaves are constant challenges, filters fill up faster than in other areas. We recommend professional cleaning every 6 months for cartridge filters and backwashing plus deep cleaning annually for sand and DE filters. When a filter reaches the end of its life, we handle complete replacements with top-quality equipment.
We Service All Filter Types
Different filters need different care. Here is what we do for each type:
- Cartridge Filters: Remove and spray clean each pleat, soak in filter cleaner solution, inspect for tears or damage
- Sand Filters: Backwash to clear trapped debris, inspect sand condition, replace sand when filtration drops
- DE Filters: Backwash and strip grids, clean grids thoroughly, recharge with fresh diatomaceous earth
- Check all O-rings, seals, and gaskets for wear
- Inspect filter housing for cracks or damage
- Test pressure gauge accuracy
Signs Your Filter Needs Attention
Your pool tells you when the filter is struggling. Watch for cloudy water that will not clear up even after shocking. If your pressure gauge reads 8 to 10 PSI higher than normal, the filter is clogged and needs cleaning. Shorter run times between backwashes mean your filter is losing effectiveness. You might also notice your pump working harder or making unusual sounds because it is fighting against a blocked filter.
Many Castro Valley homeowners call us when their water just will not stay clear no matter what chemicals they add. Often the culprit is a dirty or failing filter that cannot keep up with debris. Our professional pool maintenance includes regular filter checks so you never reach crisis mode. Clean filters mean clearer water with less chemical use and lower energy bills.
When to Replace Instead of Clean
Filters do not last forever. Cartridge filters typically need replacement every 2 to 5 years depending on use and maintenance. Sand should be changed every 5 to 7 years. DE grids last 3 to 5 years before they start to tear or degrade. When we service your filter, we check for signs it is time to replace rather than just clean.
We install high-quality replacement filters that match your pool size and usage. Upgrading to a larger or more efficient filter can improve water clarity and reduce equipment repairs down the road. If you are tired of constant filter problems or considering an upgrade, we help you choose the right system. Combined with regular weekly cleaning, a quality filter keeps your pool in perfect shape year-round.
