We have a new inground pool with an in-floor cleaning system, spa fountain, and waterfall. As the system cycles through the various cleaning zone, the filter (4 cartridges) pressure gauge varies from 30 to 38 pounds. I've been told that it ought to be 10-15 psi. Is this correct? The filter cartridges are new. Do I have a problem with the piping?
Thank You,
