Hi all, I've been reading other posts but still wanted to post my own. We finally got our new pool up and running. It's 27' round above ground, two speed pump (2 hp i believe), with cartridge filter and chlorine tablet holder thing When on high, the psi is between 10 and 15. However on low, the psi is at 0. I've read the gauges can be bad from the get go, but you'd think if that was my issue it would read 0 on high also. Everything seems to be fine - good seals, no air in system, great flow. Any ideas or suggestions? Thanks!
