Pool Filter Cleaning & Replacement

Why Your Pool Filter Matters

Your pool filter is the hardest working piece of equipment you own. It runs for hours every day, pulling water through and trapping dirt, debris, oils, and contaminants. Without a properly functioning filter, your pool water would turn cloudy and unsafe within days.

Think of your filter like the kidneys of your pool. Just as your kidneys clean your blood, your filter cleans your pool water. When it gets clogged with debris, it can't do its job effectively. Your water gets cloudy, your pump has to work harder, and your energy bills go up.

Regular filter cleaning is one of the most important parts of pool maintenance in Diamond Bar. We recommend having your filter professionally cleaned at least twice a year, or more often if your pool gets heavy use or sits near trees.

Three Main Types of Pool Filters

We service all three types of pool filters commonly found in Diamond Bar. Each type has its own cleaning requirements and lifespan. Here's what you need to know about each one.

• Sand Filters: Use special sand to trap debris. Need backwashing every few weeks and sand replacement every 3-5 years
• Cartridge Filters: Have removable cartridges that need cleaning every 2-4 weeks and replacement every 1-3 years
• DE (Diatomaceous Earth) Filters: Provide the finest filtration but require DE powder addition and grid cleaning twice yearly

No matter which type you have, we know how to clean and maintain it properly. If you're not sure what filter type you have, we can identify it during our first visit.

Complete Filter Cleaning and Replacement

When you schedule filter service with us, we do a thorough job. For cartridge filters, we remove the cartridges, spray them clean with a high-pressure hose, and soak them in a special cleaning solution to remove oils and minerals. Then we rinse them again and reinstall them properly.

For sand and DE filters, we perform a complete backwash, inspect the internal components, and add fresh media when needed. We also check all valves, gauges, and connections to make sure everything is working correctly.

If your filter is beyond cleaning and needs replacement, we'll let you know. We carry quality replacement cartridges, sand, and DE powder. For major pool equipment repairs or upgrades, we can replace entire filter systems with more efficient models. And if you want to prevent filter problems before they start, ask about our weekly maintenance service that includes regular filter checks.

Signs Your Filter Needs Attention

How do you know when it's time to clean or replace your filter? Your pool will tell you. Watch for these warning signs that mean your filter needs professional service.

Cloudy water is the most obvious sign. If your pool stays hazy even though your chemicals are balanced, your filter probably can't keep up. High pressure readings on your filter gauge mean the filter is clogged and struggling to push water through. Shortened filter cycles or your pump running longer than usual also point to filter problems.

You might notice poor water circulation, with some areas of your pool staying dirty while others are clean. Or maybe your pool is using more chemicals than normal because the filter isn't removing contaminants effectively. Any of these issues mean it's time to call us for filter service.
