Professional pool filter cleaning and replacement service in San Leandro, CA

Why Your Pool Filter Matters More Than You Think

Your pool filter is like the kidneys of your pool. It's constantly working to remove dirt, debris, bacteria, and other contaminants from your water. When your filter gets clogged or stops working properly, everything else falls apart. Your water gets cloudy, chemicals don't work as well, and your pump has to work harder, which drives up your energy bills.

Most pool owners in San Leandro don't realize their filter needs regular cleaning and eventual replacement. You can't just set it and forget it. Over time, dirt builds up inside the filter media, whether you have a sand filter, cartridge filter, or DE (diatomaceous earth) filter. Each type needs different care, and we know exactly how to maintain all of them.

Types of Pool Filters We Service

There are three main types of pool filters, and each one has its own maintenance needs. Here's what you need to know:

  • Sand Filters: Need backwashing every few weeks and complete sand replacement every 3 to 5 years
  • Cartridge Filters: Require cleaning every 2 to 4 weeks and cartridge replacement every 1 to 2 years
  • DE Filters: Need backwashing and fresh DE powder regularly, with grids replaced every 2 to 3 years

Not sure what type of filter you have? No problem. We'll identify it during our visit and explain exactly what maintenance schedule makes sense for your specific system. Most San Leandro pools have cartridge or sand filters, which are relatively easy to maintain when you know what you're doing.

Signs Your Filter Needs Attention

Your pool will tell you when something's wrong with the filter. Here are the most common warning signs we see:

  • Water stays cloudy even after adding chemicals
  • Pressure gauge shows consistently high or low readings
  • Pool takes longer than usual to clear after adding shock
  • You notice reduced water flow from return jets
  • Filter cycles are running longer than normal
  • You see dirt or debris returning to the pool after filtering

If you're seeing any of these signs, your filter probably needs professional cleaning or replacement. Ignoring filter problems doesn't just affect water quality. It can damage your pump and other equipment, leading to expensive repairs down the road. Our San Leandro pool service team can diagnose filter issues quickly and get your system back to peak performance.

What's Included in Our Filter Service

When we service your filter, we don't just rinse it off and call it good. We do a thorough job that actually makes a difference. For cartridge filters, we remove each cartridge, spray them down with a high-pressure hose, soak them in filter cleaner to break down oils and minerals, and inspect for tears or damage. If they're worn out, we'll recommend replacement.

For sand and DE filters, we perform complete backwashing to flush out trapped debris, inspect the internal components like laterals and grids, and add fresh sand or DE powder as needed. We also check all the valves, o-rings, and seals to make sure nothing is leaking or about to fail.

Regular filter maintenance is part of our weekly pool cleaning service, but we also offer standalone filter cleaning for pools that just need this specific service. If your equipment is old or constantly giving you problems, take a look at our pool equipment repair options to see if it's time for an upgrade.
