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,

Hank, There is no such thing as "normal pressure". As resistance to flow increases, the pressure goes up. When operating a spa, the pressure will normally be higher than typical pool operation. This is because the orfice size in spa jets are smaller. We give up volume for velocity. The same is true with your in-floor cleaner. They will ALWAYS run at a higher pressure than a standard return system.
