Pool Filter Cleaning & Replacement

Think of your pool filter as the kidneys of your swimming pool. Just like your body needs kidneys to remove waste, your pool needs a working filter to remove dirt, debris, and contaminants. When your filter isn't working properly, everything else falls apart. The water gets cloudy, chemicals don't work as well, and you end up fighting problems that shouldn't exist.

We work with pools throughout South Gate, CA, and we've seen what happens when filters get neglected. Most homeowners don't think about their filter until something goes wrong. But regular filter cleaning and maintenance prevents those problems before they start. It saves you money, keeps your water clearer, and extends the life of your entire pool system.

Not all pool filters work the same way. Each type has its own maintenance requirements and cleaning schedule. We're experienced with all three major types and can service whatever system you have.

Your filter is trying to tell you when it needs help. Watch for these warning signs:

• Water clarity decreases even with proper chemical balance
• Filter pressure gauge reads 8-10 PSI higher than normal
• Water flow from return jets feels weaker than usual
• Pool takes longer than normal to clear after use
• You find more debris on the bottom despite regular cleaning
• Filter runs constantly but water stays cloudy
• Visible dirt or algae in the filter tank or housing

We don't just give your filter a quick rinse and call it good. Our process thoroughly removes buildup and restores filtering efficiency. The exact steps depend on your filter type, but we always start by inspecting the entire system for problems.

For cartridge filters, we remove each cartridge and inspect it for damage. We use professional filter cleaning solutions that break down oils, minerals, and organic material that simple rinsing won't remove. We spray each cartridge thoroughly, reaching between every pleat. If we find tears, crushing, or excessive wear, we recommend replacement.

Sand and DE filters get backwashed properly, running the cycle long enough to fully clean the media. We check the multiport valve for leaks and ensure it's operating correctly. For DE filters, we add the precise amount of fresh DE powder your system needs.

Eventually, every filter reaches the end of its useful life. Trying to maintain an old, worn-out filter costs more in the long run than replacing it. We'll be honest with you about your filter's condition. If we think replacement is the better option, we'll explain why and give you choices that fit your budget.

Filter cartridges typically last 2-3 years with proper care. Sand should be replaced every 3-5 years. DE grids can last 7-10 years if maintained well. But these are just guidelines. Heavy use, poor water balance, or lack of maintenance can shorten these lifespans significantly. We've seen cartridges fail in a year and sand that needed changing after 18 months.

Your filter doesn't work alone. It's part of a system that includes your pump, plumbing, and regular cleaning. When we service your filter, we check how everything works together. Sometimes what looks like a filter problem is actually a pump issue or a circulation problem. Other times, chronic cloudiness that seems like a filtration issue is actually a chemical imbalance that needs equipment repairs.
