Hello, newbie here that just finished construction on an in-ground spa only setup. Quick bit of info on setup: I have a natural rock waterfall that spills into spa/spool, and has another 3' spillover on the front that goes into a small pool of water below (approx 1800 Gals total) I have pumps running the system (two 3hp Intelliflow VS, and one 2hp Whisperflo). I have 10 jets in the spa that is approx 100' away from my equipment. We have had problems with jet pressure since the first time we fired up the system. After approx 2 weeks of troubleshooting we now have 2 jets out of our 10 that seem to have the pressure that we would expect all of them to have. Any help would be greatly appreciated as we are completely new to spa ownership and our contractor is admitting that something isn't right but doesn't seem to know how/want to fix it.
I have a lot more info and pics of plumbing prior to construction that I can post as I try and work through this frustrating problem. I just didn't want to start the post with all of it or I didn't think anyone would take the time to read it all?
