I believe that my current sand filter pressure gauge is not showing the correct pressure. I am considering purchasing a new pressure gauge. However, how can you determine if a pressure gauge is working correctly? While it is not critical for a gauge to be exact if it does not measure pressure within industry standards I would like to return it for a better gauge. The pressure on my sand filter increases slowly. Pool stores are not receptive to accepting a return after six months. How can you increase the pressure to determine if the gauge shows an increase the first day?
I am not experiencing any water balancing problems. I cannot determine when to backwash; the gauge has increased from 22 to 23 over 6 weeks.
