How do I know if my filter is dirty?

Check your pressure gauge. If it reads 8 to 10 PSI higher than normal, your filter is clogged. You might also notice cloudy water or weak water flow from your jets. These are all signs your filter needs cleaning.

Can I clean my pool filter myself?

You can do basic cleaning, but professional service is more thorough. We use high-pressure spray tools and cleaning solutions that remove buildup you can not get with a regular hose. We also inspect for damage that could cause problems later.

What type of filter is best for my pool?

It depends on your pool and your budget. Cartridge filters are easy to maintain. Sand filters are affordable and last a long time. DE filters provide the cleanest water but need more attention. We can help you choose the right type if you are replacing your system.

Why Your Filter Is the Most Important Part of Your Pool

Your pool filter is like the lungs of your pool. It pulls water through, traps dirt and debris, and sends clean water back in. When your filter gets clogged or old, your water turns cloudy, chemicals do not work properly, and algae starts growing.

Most pool owners in Antioch, CA do not think about their filter until something goes wrong. But regular filter cleaning keeps your pool clear and your equipment running smoothly. A clean filter also saves you money on chemicals because balanced water needs fewer adjustments.

We work on all types of filters including cartridge, sand, and DE filters. Whether you need a deep clean, backwash, or full replacement, we handle it all. Our technicians know exactly what each filter type needs to perform at its best.

Filter Cleaning and Replacement Services

Different filters require different care. Here is what we offer for each type:

Cartridge Filter Cleaning

Cartridge filters trap dirt in pleated material. Over time, the pleats get clogged and water flow slows down. We remove the cartridge, spray it clean, and check for tears or damage. If your cartridge is worn out, we can replace it with a new one.

Sand Filter Backwashing

Sand filters use fine sand to catch debris. When the sand gets dirty, we backwash the system to flush it out. Every few years, the sand needs to be replaced completely. We handle both regular backwashing and full sand replacement.

DE Filter Cleaning

DE (diatomaceous earth) filters are the most effective but also the most complicated. They use a fine powder to filter out even tiny particles. We backwash the system, clean the grids, and add fresh DE powder. If the grids are damaged, we replace them.

How Often Should You Clean Your Filter?

Most filters need cleaning every 4 to 6 months depending on how much you use your pool. If you have a lot of trees nearby or your pool gets heavy use, you might need more frequent cleanings.

You will know your filter needs attention when the pressure gauge reads higher than normal, your water looks cloudy, or the flow from your return jets is weak. If you are on our weekly pool cleaning service, we monitor your filter pressure and let you know when it is time for a cleaning.

Filter replacement depends on the type. Cartridge filters last 1 to 2 years. Sand should be replaced every 5 to 7 years. DE grids can last 7 to 10 years if maintained properly. We always inspect your filter and give you honest recommendations about whether to clean or replace.

If your filter is not working right, it can affect your whole pool system. You might also need pool equipment repairs to fix pumps, valves, or other components. We check everything during our service calls.
