Pool Filter Cleaning & Replacement

Your Filter Is the Heart of Your Pool

Most pool owners do not think much about their filter until something goes wrong. But your filter works harder than any other piece of equipment. It runs for hours every day, removing dirt, debris, oils, and microscopic particles that cloud your water. When your filter gets dirty or worn out, your entire pool suffers. Our pool filter cleaning service in San Angelo keeps your filtration system running efficiently so your pool stays crystal clear.

A clean filter does more than just make your water look better. It protects your pump from overworking, reduces chemical consumption, and prevents algae growth. It saves you money on electricity because your pump does not have to work as hard to move water through a clean filter. Regular filter maintenance is one of the smartest investments you can make in your pool.

Types of Pool Filters We Service

San Angelo pools use three main types of filters, and we service them all. Each type has different cleaning requirements and maintenance schedules.

• Sand filters use special pool sand to trap debris. They need backwashing weekly and sand replacement every 3 to 5 years. Sand filters are durable and low maintenance but provide the least filtration of the three types.
• Cartridge filters use pleated fabric cartridges to trap particles. They need cleaning every 2 to 4 weeks depending on use and pool conditions. Cartridges typically last 1 to 3 years before replacement. These filters provide excellent filtration and are easy to maintain.
• DE filters use diatomaceous earth powder to create a fine filtration layer. They provide the best water clarity but require more maintenance. DE filters need backwashing and fresh DE added regularly, plus periodic deep cleaning to remove buildup.

No matter what type of filter you have, we know how to maintain it properly. We bring the right tools and materials to clean your specific filter type. If your filter needs replacement, we can handle that too.

Signs Your Filter Needs Cleaning

Your filter will tell you when it needs attention if you know what to look for. High pressure on your filter gauge means the filter is clogged and straining to work. Most filters should read 10 to 15 PSI when clean. When pressure rises 8 to 10 PSI above the clean baseline, it is time to clean or backwash your filter.

Other warning signs include cloudy water that will not clear up even with proper chemicals, reduced water flow from your return jets, or your pump running louder than normal. If you notice your pool taking longer to clear after storms or struggling to maintain clarity between cleanings, a dirty filter is usually the culprit. Pools in San Angelo face extra challenges from wind-blown dust and debris, so filters here work harder and need more frequent cleaning than in other areas. If you are experiencing persistent cloudiness, our deep cleaning service can help reset your pool while we address the filter.

Our Filter Cleaning Process

Professional filter cleaning goes beyond a simple backwash or rinse. We completely disassemble cartridge and DE filters to access all the internal components. Each cartridge or grid gets thoroughly cleaned with specialized tools and solutions that break down oils, minerals, and organic matter that water alone cannot remove.

For cartridge filters, we use high-pressure rinses and filter cleaning solutions to flush out debris trapped deep in the pleats. We inspect each cartridge for tears, compressed pleats, or worn fabric that reduces filtration effectiveness. For sand filters, we perform thorough backwashing and can replace old sand that has lost its filtering ability. DE filters get stripped down, cleaned, and reassembled with fresh DE powder for optimal performance.

After cleaning, we check all O-rings, gaskets, and seals for wear. These small parts prevent leaks and maintain proper pressure. We replace them if needed so your filter does not develop leaks later. Finally, we reassemble everything correctly and check for leaks before we leave. Many filter leaks happen simply because parts were not reassembled properly. If we find equipment issues beyond the filter during service, our equipment repair service can address those problems too.
