A clean, sparkling pool depends on a properly functioning filter. Your pool’s filter is the first line of defense against dirt, debris, algae, and bacteria. If it’s not doing its job, your pool water can quickly turn cloudy, unsafe, and uninviting.

Knowing when to repair or replace your filter can prevent major headaches and help your entire system operate more efficiently. Let’s explore what to look for and how A&N Pool Solutions can help.

How a Pool Filter Works

Your filter pulls in water, traps debris, and returns clean water to the pool. There are three main types:

• Sand Filters: Use a bed of sand to capture particles as water passes through.
• Cartridge Filters: Use pleated cartridges to filter out small debris.
• DE (Diatomaceous Earth) Filters: Use a powder-coated grid for superior filtration down to the finest particles.

Each system has its own maintenance needs and lifespan.

Signs You Need Pool Filter Repair or Replacement

If your pool water isn’t crystal clear, your filter might be the problem. Here are common signs to watch for:

• Cloudy Water: Even after treating with chemicals, poor filtration may be the cause.
• Low or No Pressure: Could mean a clog, broken gauge, or internal damage.
• Short Filter Cycles: If your filter clogs quickly, it may be deteriorating internally.
• Visible Leaks: Cracks or damaged seals in the filter tank or multiport valve.
• Old Age: Most filters last 5–10 years, depending on type and maintenance.

Repair vs. Replacement: What’s Best?

✅ Repair:

• Minor part issues (gaskets, pressure gauge, clamp bands)
• Broken laterals in a sand filter
• Cartridge replacement in otherwise healthy filter housing

🔁 Replace:

• Cracked or warped filter housing
• Frequent clogging or poor performance
• Outdated or discontinued models
• DE grids or cartridges needing full system replacement

A professional inspection can quickly determine the best path forward.

Benefits of Filter Upgrades

Modern pool filters are more energy-efficient and require less maintenance. Upgrading offers:

• Improved water clarity
• Lower chemical usage
• Reduced strain on pumps
• Easier maintenance and longer cycles
