Pool Filter Cleaning & Replacement
Keep your pool water crystal clear with professional filter cleaning and replacement services in Duncanville, TX.
Your Filter Is Your Pool's Most Important Equipment
Your pool filter does the heavy lifting of keeping water clean. It removes dirt, debris, oils, and microscopic particles that make water cloudy or unsafe. Without a properly functioning filter, even the best chemicals can't keep your pool clear.
Over time, filters get clogged with the very contaminants they're designed to remove. Oils, lotions, dead algae, and mineral deposits build up inside filter media and reduce flow. When flow decreases, your entire system works harder and less efficiently. Your pump strains, chemicals don't circulate properly, and water quality suffers.
Most homeowners in Duncanville don't realize their filter needs deep cleaning until their pool turns cloudy or equipment starts making strange noises. Regular filter maintenance prevents these problems and extends the life of your entire pool system. Our professional pool maintenance service includes filter inspection and can alert you when deep cleaning is needed.
We Service All Types of Pool Filters
Different filter types require different cleaning methods. We have the knowledge and equipment to properly clean and maintain every filter system commonly found in Duncanville pools.
Three Main Filter Types
- Sand filters: These use special sand to trap particles as water flows through. Sand filters are popular because they're affordable and low-maintenance. However, the sand needs complete replacement every 3 to 5 years, and the filter requires backwashing regularly to remove trapped debris.
- Cartridge filters: These use pleated fabric cartridges to catch particles. They're more efficient than sand filters and require less backwashing. Cartridges need removal and deep cleaning 2 to 4 times per year, and replacement every 1 to 3 years depending on usage and care.
- DE (diatomaceous earth) filters: These provide the finest filtration using powder made from fossilized organisms. DE filters catch particles as small as 3 to 5 microns, giving you the clearest water. They require periodic backwashing and fresh DE powder, plus complete grid cleaning once or twice per year.
We'll inspect your specific filter system and explain what it needs. If your filter is beyond cleaning and needs replacement, we can handle that too. We'll help you choose the right replacement filter for your pool size, budget, and preferences.
Our Professional Filter Cleaning Process
We don't just rinse your filter with a hose and call it clean. Professional filter cleaning involves complete disassembly, thorough cleaning of every component, and proper reassembly. Here's what we do during a complete filter cleaning service.
For cartridge filters: We shut down your pump and release pressure from the system. We open the filter tank and carefully remove cartridge elements. Each cartridge gets sprayed with high-pressure water to remove surface debris, then soaked in professional filter cleaning solution that breaks down oils, minerals, and organic matter. After soaking, we rinse cartridges thoroughly until water runs clear. We inspect cartridge pleats for tears, damage, or worn areas that indicate replacement is needed. Finally, we reassemble everything with proper lubrication on O-rings and seals.
For sand filters: We perform thorough backwashing to flush trapped debris out of the sand bed. If your filter hasn't been cleaned in a long time, we may recommend using filter cleaner chemical that dissolves oils and organic buildup within the sand. In cases where sand is old or contaminated, we'll recommend complete sand replacement, which involves draining the tank, removing old sand, and refilling with fresh filter sand.
For DE filters: We backwash to remove old DE powder and trapped debris. We open the filter tank and remove grid assemblies. Each grid gets carefully cleaned and inspected for tears or damage. We clean the manifold and all internal components. After reassembly, we add fresh DE powder through the skimmer in the correct amount for your specific filter model.
After cleaning any filter type, we test the system to ensure proper flow, check for leaks, and verify everything operates correctly. Many homeowners who called us for filter cleaning discover they also need minor equipment repairs like new O-rings, gaskets, or pressure gauges. We can handle these repairs during the same visit.
Signs Your Filter Needs Cleaning or Replacement
How do you know when your filter needs attention? Here are the most common warning signs we see in Duncanville pools that indicate it's time for professional filter service.
Cloudy water despite balanced chemicals: If your water tests show good chemical balance but still looks hazy or dull, your filter probably can't keep up with contaminant removal. It's too clogged to function properly.
Increased pressure gauge reading: Your filter has a pressure gauge that shows how hard it's working. When pressure rises 8 to 10 psi above the normal clean reading, the filter is clogged and needs cleaning.
Decreased water flow: If jets and returns have noticeably weaker flow than normal, or if your automatic pool cleaner moves slowly, restricted filter flow is often the cause.
Dirty water returning to pool: If you see dirt or debris coming back through your return jets after vacuuming, your filter cartridges may be torn or your sand may need replacement.
Frequent need to backwash: If you find yourself backwashing more than once a week or if backwashing doesn't improve pressure, it's time for deep cleaning or media replacement.
It's been more than a year: Even if everything seems fine, filters should be professionally cleaned at least once a year. Preventive maintenance is always cheaper than emergency repairs or complete system failure.
