Pool Filter Cleaning & Replacement

Why Your Filter Matters More Than You Think

Your pool filter is the hardest working part of your pool system. It runs for hours every day pulling water through and trapping dirt, debris, oils, and algae. Over time, all that junk builds up inside the filter. When the filter gets clogged, water cannot flow properly. Your pump has to work harder. And your pool stays cloudy no matter how much chlorine you add.

Most pool owners in Seguin do not realize their cloudy water problem is actually a dirty filter problem. They keep adding chemicals and the water never clears. That is because the filter is too clogged to catch anything. Regular filter cleaning and maintenance fix this issue and save you money on wasted chemicals.

The Three Types of Pool Filters

There are three main types of filters and each one needs different care. Here is what we service:

• Sand Filters: These use sand to trap debris. We backwash them to flush out the dirt. The sand needs replacement every 3 to 5 years.
• Cartridge Filters: These have removable cartridges that we take out and hose down. Cartridges last 1 to 3 years depending on use.
• DE Filters: These use diatomaceous earth powder. They catch the smallest particles but need careful cleaning and recharging.

How Often Should You Clean Your Filter?

Sand filters should be backwashed every 4 to 6 weeks during swim season. Cartridge filters need cleaning every 2 to 4 weeks depending on pool usage. DE filters need attention every month or when the pressure gauge shows high pressure. If you have heavy tree coverage or lots of swimmers, you might need more frequent cleaning.

Our Filter Cleaning Service

We handle all filter types and sizes. When you call us for filter service, here is what happens:

• Inspect the filter and check the pressure gauge reading
• Backwash sand filters or remove and rinse cartridge filters thoroughly
• Check for tears, cracks, or damage to filter media
• Clean or replace O-rings and gaskets if worn
• Recharge DE filters with fresh powder
• Test the system to ensure proper water flow and pressure

If we find that your filter media is too old or damaged, we recommend replacement. Running a damaged filter wastes energy and lets dirty water back into your pool. We can replace sand, cartridges, or DE grids right on the spot so your pool stays clean.

Why Filter Cleaning Is Part of Good Pool Care

A clean filter makes everything else easier. Your weekly pool service works better because the water circulates properly. Your chemicals balance faster. Your pump uses less electricity. And your water stays clear and inviting all season long.

Many Seguin homeowners only think about the filter when something breaks. But regular filter maintenance prevents expensive repairs. A clogged filter forces your pump to strain. That can burn out the motor and cost hundreds or thousands to replace. For our equipment repair customers, filter neglect is one of the top causes of pump failure.
