Cartridge filters life

[ciaka]

Have my pool for about 2.5 years.
4 cartridge filters that came in filter, are still the original set I bought at pool construction.
I clean pool often, pressure on filter never raises more than 2 or 4 psi higher than pressure when cartridges are new or just after claning.

Is there relace timeline?
A I keep using till presdure increases?
Advice? Thank you.

When should I look into replacing?

With proper cleaning and avoiding pool store products (i.e. floc, clarifiers) that could gum-up a filter, your carts should last several years. Mine are going year 9. Other than some discoloration and a few broken glue spots when there bands connect, it's fine.

c,

I suggest that you clean the cartridges once a year, no matter what the pressure gauge shows.

Most cartridges should last 6 to 10 years.

J typically try cleaning them 2x a year. It's time for another clean but I just wonder if they wear out and mandate replacement even idmf oressure is ok.

c,

If your pressure is normal and they look ok, then there is no reason to replace them.

Thanks,

Good to hear. They look good, unborn or not packed up or gritted up when clean. Thank you.
