Hello everyone,
I’ve read the forum for years. I’m a DIY type home owner with a 30,000 gallon L shaped salt water pool. It uses a pentair salt generator and pentair 3 horsepower intelliflow pumps. One for the pool/spill over hot tub and one for the waterfall. The waterfall has its own plumbing.
So I had my pool renovated in 2016 and added a spill over spa. It has 8 jets. It’s 96 inches I think. It has two Venturi knobs on top that let you had some bubbles and thrust. The main pool pump runs the spa when the valves are isolated for it.
Anyway... my pool guy who I’ve has for years suggested I add a spa blower. Sounded good. I let him do the install. Except... fail. He brought a 2 horsepower air supply silencer blower. He cut a Tee into the return line/output line to the spa. Wired 240 from the sub panel. I did the breaker and the whip for him. I had it all ready. GFI 15 amp. My part was fine. So he used a standard T and attached it right to the 2 inch return just passed the 3 way valve at the manifold. It didn’t work. When the pump is running water back pressures right up to the check valve for the air supply pump.
I don’t think he knows what to do Now he says it’s not making bubbles because it’s not “strong enough” and maybe a 3-4 horsepower blower will work.... except I don’t even think they make those for residential pools!
His next move is to try to tee into the main return line from the sand filter that goes to the manifold, all the return jets, and the spa. But I am pretty sure the same thing is going to happen.
Where is that blower supposed to be Tee’d into.. the plumbing? Will a “venturi” tee into the return line of the spa do the job? With a Venturi Tee it should just “Inject air” into the line right?
I’m very handy. I’ve changed my own pumps, done my own electrical and plumbing. I knew not to mess with this because I didn’t know enough about it and trusted the pool guy. He’s been in business a long time and I suspect has changed plenty of “bad ones”but I’m guessing he never added one before.
How should this thing be plumbed?
Thanks
