5 Signs Your Pool Filter Needs Replacement

When to Replace Your Pool Filter

Sand filters typically last 5-7 years with proper maintenance. However, several warning signs indicate it's time for a replacement before problems escalate.

1. Consistently High Pressure

If your filter pressure gauge reads 8-10 PSI above the clean baseline even after backwashing, the sand media has likely become clogged beyond recovery.

2. Sand in the Pool

Finding sand at the bottom of your pool means the laterals (internal distribution tubes) are cracked. This requires immediate attention.

3. Short Filter Cycles

If you need to backwash every few days instead of weekly, the filter media can no longer trap particles effectively.

4. Poor Water Clarity

Persistent cloudiness despite proper chemical balance usually points to filter inefficiency. The sand grains become smooth over time and lose their filtration ability.

5. Visible Damage

Cracks in the tank, leaking valves, or corroded internals are clear signs of replacement need.
