Your pool filter is the key to keeping your Scottsdale pool water clear, but when it’s dirty or failing, your pool can quickly turn cloudy, unbalanced, or unsafe. Arizona’s heat, dust, and hard water put extra strain on filters, making regular maintenance essential. Here are the most common signs that indicate your pool filter needs cleaning or replacement and how to keep your system running efficiently.
1. Cloudy or Murky Pool Water
One of the first signs of a clogged or failing pool filter is cloudy or murky water. If your pool water remains unclear even after balancing chemicals, your filter may not be removing debris properly. Scottsdale’s frequent dust storms and hard water minerals can quickly overwhelm filters, reducing their effectiveness.
How to Fix It:
- Check your filter pressure gauge (high pressure usually means it’s clogged).
- Clean or backwash your filter, depending on the type.
- If cloudy water persists, consider replacing the filter media or cartridges.
2. Weak or Reduced Water Flow
A dirty or clogged filter can restrict water flow, making it harder for your pump to circulate water efficiently. If you notice weak return jets or your pool cleaner isn’t moving as usual, your filter may be overdue for cleaning.
How to Fix It:
- Check for visible dirt, debris, or buildup in the filter.
- Perform a deep clean or replace clogged filter cartridges.
- Ensure your pool pump is running the correct hours for Scottsdale’s climate (8–12 hours in summer).
3. High Filter Pressure Readings
Your filter has a pressure gauge that indicates its efficiency. When the pressure is too high, it means the filter is clogged and needs cleaning. If left unchecked, this can put strain on your pump, increasing the risk of costly repairs.
How to Fix It:
- Clean or backwash your filter when the pressure rises 8-10 psi above normal operating levels.
- If pressure remains high after cleaning, your filter media may need replacing.
4. Frequent Algae Growth
Scottsdale’s hot climate makes pools more prone to algae, especially in summer. If algae keeps returning even after treatment, a dirty filter could be the cause. Algae spores get trapped in filters, allowing them to spread back into the pool.
How to Fix It:
- Deep clean the filter after an algae bloom.
- Run the pump longer and maintain proper chlorine levels.
- If algae growth persists, your filter may need replacing.
5. Filter Media Looks Worn or Damaged
Over time, pool filter cartridges, sand, and DE grids degrade. If your filter media looks torn, excessively dirty, or no longer holds pressure, it’s time for a replacement.
How to Fix It:
- Cartridge filters: Replace every 2–5 years, depending on usage.
- Sand filters: Change the sand every 5–7 years.
- DE filters: Replace the grids every 5–10 years.
