Why Your Pool Filter Matters More Than You Think

Your pool filter is the hardest working piece of equipment you own. It runs for hours every day removing dirt, debris, oils, and microscopic particles that make water cloudy. When it gets clogged or worn out, everything suffers. Your water gets murky, your chemicals do not work as well, and your pump works harder.

Most Pacifica homeowners do not realize their filter needs regular deep cleaning beyond simple backwashing. Filters accumulate oils, minerals, and buildup that normal rinsing cannot remove. We use specialized techniques and cleaning solutions to restore your filter to like-new performance.

Whether you have a cartridge, sand, or DE filter, we handle all types. Regular filter maintenance is part of our comprehensive pool care services and makes a huge difference in water quality.

How We Clean Each Type of Filter

Different filters need different care. Here is how we maintain each type:

Cartridge Filters

We remove your cartridge and spray it with high-pressure water to remove debris between the pleats. Then we soak it in a professional filter cleaning solution that dissolves oils, sunscreen, and mineral deposits. After rinsing thoroughly, we inspect for tears or damage. Cartridges typically need deep cleaning every 3 to 6 months and replacement every 1 to 3 years.

Sand Filters

Regular backwashing helps but does not remove everything. We perform deep backwashing and use filter cleaner to break down oils and scale buildup in the sand. Over time, sand gets worn smooth and stops filtering properly. We test your sand and recommend replacement every 5 to 7 years to maintain peak performance.

DE Filters

Diatomaceous earth filters are the most effective but require the most maintenance. We backwash to remove old DE powder, then open the filter to clean the grids by hand. We inspect each grid for tears and recharge with fresh DE powder. DE filters need this service 2 to 4 times per year for best results.

Clean filters work hand in hand with regular pool maintenance to keep your water sparkling all year.

Signs Your Filter Needs Cleaning or Replacement

Your pool will tell you when something is wrong with the filter. Watch for these warning signs:

  • Water that stays cloudy even after shocking and balancing chemicals
  • Higher than normal pressure gauge reading on your filter tank
  • Weak water flow from your return jets
  • Shorter time between needed backwashes or cleanings
  • Your pump running louder or working harder than usual
  • Visible tears, cracks, or damage to cartridge filters
  • Sand or DE powder showing up in your pool

If you notice any of these issues, we also offer pool equipment repair services to fix pumps, valves, and other system components.
