Pool Filter Cleaning & Replacement

Your Filter Does More Work Than You Think

Your pool filter is working hard every single day to keep your water clean. It captures dirt, debris, oils, pollen, and tiny particles you cannot even see. Over time, all that trapped material builds up and makes your filter less effective. When your filter is not working properly, your water gets cloudy, chemicals do not work as well, and your pump has to work harder.

Regular filter cleaning is one of the most important things you can do to maintain clear, healthy pool water. Here in San Juan Capistrano, we see pools every day where dirty filters are causing problems that could easily be prevented. Our professional pool care team has the knowledge and equipment to clean all types of filters quickly and thoroughly.

We Service All Types of Pool Filters

Different pools have different types of filters, and each one requires specific maintenance. We work with all three main types:

• Cartridge Filters: These have removable cartridges that need to be rinsed and deep cleaned regularly, then replaced every 1 to 2 years depending on use.
• Sand Filters: These use special sand to trap debris and need backwashing regularly, plus complete sand replacement every 3 to 5 years.
• DE (Diatomaceous Earth) Filters: These provide the finest filtration but need the most maintenance, including regular backwashing and fresh DE powder after each cleaning.

No matter what type of filter you have, we know exactly how to service it properly. We can also help you understand which type might be best if you are considering an upgrade or replacement.

What Happens During a Professional Filter Cleaning

For cartridge filters, we remove the cartridges, inspect them for damage or wear, and clean them thoroughly using professional filter cleaning solution and high-pressure water. This removes oils, minerals, and embedded debris that a simple hose rinse cannot touch. We also check the filter housing, o-rings, and all seals to make sure everything is in good condition.

For sand and DE filters, we perform a complete backwash, check the pressure gauge and multiport valve, and inspect the internal components. If your sand is old or your DE grids are damaged, we will let you know and explain your options. Many homeowners combine filter service with equipment inspection and repair to make sure their entire system is running efficiently.

Signs Your Filter Needs Attention

Your pool will tell you when your filter is struggling. Watch for these warning signs:

• Water that stays cloudy even after adding chemicals
• Pressure gauge reading 8-10 PSI higher than normal
• Weak water flow from return jets
• Pool taking longer to clear up after use or rain
• Visible dirt or debris returning to the pool
• Filter cartridges that look permanently stained or damaged

If you notice any of these issues, it is time for professional filter service. Waiting too long can lead to more expensive repairs down the road and can even damage your pump. Our weekly maintenance service includes regular filter monitoring so small problems get caught before they become big headaches.

When Cleaning Is Not Enough

Sometimes filters reach the end of their useful life and need replacement. Cartridge filters typically last 1 to 2 years with proper care. Sand should be replaced every 3 to 5 years. DE grids can last longer but eventually wear out and develop tears or holes. If your filter is old, damaged, or simply not keeping up with your pool anymore, replacement might be the best option.

We only recommend replacement when it is truly necessary. We will always try cleaning first and give you honest advice about whether repair or replacement makes more sense for your situation and budget. When replacement is needed, we help you choose the right size and type for your pool, then install it correctly so it works perfectly from day one.
