When to Change Cartridges

[jhm]

I'm wondering how often you should change filter cartridges? I have had mind about 7 years, and clean them at least 3-4 times per year. Lately, it seems to have less and less effect.

Any guidelines?

Thanks!

3-5 years is an average lifespan. I would say you got your money's worth out of yours!

Thanks Waterbear! I think maybe I tried to stretch it a little too far, especially after comparing the new filters with the old.

Jhm, get the replacements but don't throw out the old carts. If something bad happens and the pool becomes a swamp, you can use the old ones for the 'heavy cleaning' without prematurely shortening the life of the new carts.

I believe that one can get a longer life out of carts by cleaning them when the pressure gauge rises 5 PSI from clean (as opposed to the often recommended 8- 10 PSI rise) - the 'stuff' doesn't become as embedded and therefore, washes out more thoroughly and easily

Good suggestion, Ted.

3-5 years?? The longest I have ever been able to get out of one is 1 1/2 years. That is for a quality replacement filter. Not a lousy Home Depot after market brand. I'll never buy a cart from Home Depot again. It lasted about six months.
