I have a 24' AG pool with SWG.
I'm just wondering when do I need to do a backwash? I have looked around and found different answers.
1) backwask every week.
2) backwask when your pressure is 4 tp 6 psi higher than the normal pressure.
3) backwash when the pressure is 8 to 10 psi higher than the normal pressure.
My pool is new and my starting pressure was 12 or 14 psi. After 2, 3 weeks, the pressure is now at 16.
What are the signs that tell me to do a backwash?
