So I'm still somewhat concerned with the returns to the pool as they gate down to very small lines, anyone that can share their words of wisdom id really appreciate it, i know most seem to think it will be fine but I have 3" in my contract so it seems that should be the feed all the way around the pool to me for the returns and gate accordingly at each head, also why wouldn't this line loop like the spa? it t's when it hits the pool and ends with about 1/6 of the pool between the two with no returns on the wall there.
-The waterfall grotto/slide is 3" suc (by spa wall) and return all the way to water feature - Made perfect sense
-The Spa is 3" suc and return is 3" to the spa wall then it gates to a 2" for the loop and down accordingly at the jets - made perfect sense
-The pool is where I'm concerned. I only have a partial infloor system PV3, all 2" lines from the pump to the water valve to the 13 heads which are cycled off of the 6 valves with only 2-3 heads unning at a time- this makes perfect sense, but this is not my primary source of circulation for the pool or efficiency as it operates under higher pressure at the pv3 heads for cleaning circulation.
The suction from the pool main drains and skimmer is 3" as per contract. - Made perfect sense.
The return however is only 3" to the pool wall by the spa (25 feet), there it T's and gates to a 2" and then as it goes around the poolfor maybe 15 feet and then it gates to 1 1/2 and 1" at the farthest point, heads off of those according. This was very concerning to me.
Why not run 3, 2 1/2, or 2 all the way around the pool and gate it down accordingly at the wall where the inlets feed into the pool for circulation? I have 3" returns in my contract, and technically he did give me a partial 3" return but its not what I was after for pump efficiency. Is that not how it should have been done, it seems there would be plenty of pressure created at each head to the pool even if the pipe were 3" and gated to 1 1/2 or 1" at the head. the builder says this is how it must be done, which i doubt, and its 3" in my contract so I'm more then glad to tell him to rip it out and fix it before the shotcrete, this is a expensive project I want it right the first time. Hope some of you can help me out there??? or tell me I'm crazy
I have a 2hp VS Jandy E Pump with SVRT for the pool and spa circulation- the flow charts call for 3" piping for suctions and returns, the only thing that it never shows is when the pipes should gate down or the size of the return heads at the pool which seem to be at the wall 1 to 1 1/2 standard to create pressure for the circulation. Help me out ladies and gents...
Thanks a million in advance!
