Pool Filter Cleaning & Replacement in North Dallas TX — What You Need to Know

Your pool pump is running but the water looks wrong — cloudy, slow to circulate, or just not clean. Nine times out of ten, the filter is the problem. Here's what you need to know about pool filter cleaning and replacement in North Dallas.

The Three Types of Pool Filters

Sand filters are the most common in North Dallas homes. They backwash to clean and last 5–7 years before the sand needs replacing. Simple, but they catch the least fine debris.

Cartridge filters are popular in Frisco, Prosper, and The Colony because they use no backwash water — good for drought restrictions. The cartridge needs rinsing every 4–6 weeks and replacing every 1–2 years.

DE (Diatomaceous Earth) filters give the finest filtration. They need backwashing plus fresh DE powder added after. Common in higher-end pools in Aubrey and Celina.

Signs Your Filter Needs Attention

Watch for these warning signs regardless of which filter type you have:

1. Pressure gauge reads 8–10 PSI above your normal baseline — the filter is clogged and flow is restricted.

2. Returns are weak even though the pump is running normally.

3. Water stays cloudy even after balancing chemicals.

4. You haven't cleaned the filter in over 6 weeks — in Texas summer heat, that's often too long.

How Often to Clean Your Pool Filter in Texas

Texas summer changes everything. High bather load, heat, wind, and pollen mean your filter works harder than the manufacturer's schedule assumes. Here's what we recommend for pools in Little Elm, Frisco, and Prosper:

Sand filters: Backwash when pressure rises 8–10 PSI above baseline, or every 4 weeks minimum in summer.

Cartridge filters: Rinse with a garden hose every 4–6 weeks. Deep clean with filter cleaner solution every 3–6 months.

DE filters: Backwash and recharge with DE every 4–6 weeks. Full teardown and cleaning twice a year.

When to Replace Instead of Clean

Cleaning only goes so far. Replace when:

1. Cartridge pleats are torn, flattened, or have permanent discoloration that won't clean off.

2. You're cleaning a cartridge every week — it's worn out and no longer holding its shape.

3. Sand filter pressure stays high even right after backwashing — the sand is channeled or caked with calcium (common with North Dallas hard water).

4. DE filter grids have tears — DE powder will pass through and cloud your pool.

A cartridge replacement typically runs $50–$150. Sand replacement $150–$300. DE grid sets vary. Compared to chemical costs from a non-functioning filter, replacement is almost always worth it.
