    1. Is that your normal PSI reading? If it is then, there is not much you can do about it. But if this is a recent occurrence you can try backwashing or cleaning the cartridges to clear debris from the filter.

  1. How do you change the flow rate? I have a sand filter. It’s at 15psi. When it drops down to 10psi I have to clean the pump basket.

  2. So my 4 psi at 30-35 (flow meter) at 1500 rpm on a variable speed pump is okay? Pool store keeps telling me I need to run it faster. (My inline chlorinator doesn’t seem to use much of its charge-despite switching to 1″tablets.) Entire pool is new. Giant Pentair sand filter (the biggest one model escapes me), Pentair in-line chlorinator.

  3. I have D.E filter 38 sq. 60 lbs pressure gage reads 4lbs , my hose vacuum cleaner works fine. auto cleaner leisure vac will not move
