Pool Filter Repair & Service Scottsdale AZ
Crystal clear water starts with a healthy filtration system. Our technicians specialize in repairing and servicing all types of pool filters to keep your water safe, clean, and inviting.
Common Pool Filter Issues & Solutions
A struggling filter can lead to cloudy water, algae growth, and increased strain on your pool pump.
We provide expert solutions for:
Short Filter Cycles: If you find yourself backwashing or cleaning your filter more often than usual, it may be time for a deep cleaning, a grid replacement, or a sand change.
Dirty or Cloudy Water: This is often a sign of “channeling” in sand filters, torn fabric in cartridge filters, or a torn manifold/grid in DE filters. We diagnose the breach to restore clarity.
Filter Tank Leaks: Leaks around the clamp, belly band, or pressure gauge can be dangerous and wasteful. We replace worn O-rings and repair or replace cracked tanks.
High Tank Pressure: High pressure usually means the filter is clogged. If cleaning doesn’t lower the PSI, there may be an internal obstruction or calcification that requires professional attention.
DE/Sand Returning to Pool: If you see filter media on the pool floor, you likely have a broken internal part, such as a lateral or a torn grid, that is allowing debris to bypass the filter.
Troubleshooting Pool Filter Problems
Try these steps before scheduling a service call:
Check the Pressure Gauge: If the pressure is 8–10 PSI above your “clean” starting pressure, it’s time for a cleaning or backwash.
Bleed the Air: Use the air relief valve on top of the tank to release trapped air. If water doesn’t eventually spray out, there may be a clog.
Inspect the Pump Basket: Sometimes the filter isn’t the problem—a clogged pump basket can mimic filter issues by reducing flow.
Look for Algae: If your water is green but the filter is clean, the issue may be chemical-based rather than mechanical.
