Question Correct Pressure

Hello I purchased a home with a 32 by 16 foot pool in the backyard. It ranges in depth from 3 to 8 feet.

The pressure gauge is reading 11 on the outer part of the gauge, what do you think it should be around?

Thank you

It depends on the size of the filter and the condition of the filter. As the filter gets dirty that pressure will go up. 11psi sounds like a tad low for a filter.

I run a 1hp Hayward with a sand/DE filter. The pool is 16'x40' and 23,000 gallons of water.
My filter runs normally around 20psi

The norm is 15-20psi but there really isn't a norm because everything can affect it. Even the return fittings where the water re-enters the pool can change that number.

Backwash the filter and when your done check the pressure. When it rises between 5-10psi it's time to backwash again.

As PJ said, there is no magic number. It helps to get a good base line with a fresh (clean). My filter runs around 20 PSI on the gage when clean and my neighbors runs a bit higher an a similar system. A lot of times, I feel the return jet and can tell from that if the filter needs back washing or not. I have done that so many times that I can tell within a couple of lbs what the gage reading is.
