We started the patio last week and I halted work as I noticed the pressure on the pipes was dropping. No equipment is installed, the pipes are all brought into a manifold with a pressure gauge. We had some pretty large temperature swings, so I thought maybe some of the loss was due to it getting colder. This week the temperature is less dramatic and it looks like I'm seeing about a 1 PSI drop per day. I don't see any moisture at any of the pipes in the pool the skimmer plugs or any of the pipe fitting I can get access to. Here is the data I've taken:
Last week, started at 20PSI. 7PSI drop from Thur to Monday; however, 30 degree drop in temperature
