Hey All -
My pool builder used 1.5" PVC throughout the entire build. For intakes, I have 2 skimmers, and 2 main drains. Skimmers each have their own path back to the pump with 1.5" PVC, and the two main drains combine together in to a single 1.5" line under the pool, so the majority of the run is 1.5". The intake lines all combine in to a 1.5" 4 way tee before running in to the Jandy VS FloPro 1.65 HP. The intake side of the pump has a 2" union, but is reduced down to 1.5".
From the output of the pump, all the Jandy equipement (cartridge filter, heat pump, sacrifical anode, valves, etc) has 2" unions on it, but the builder did 1.5" reducers and ran all 1.5" pvc. For the returns to the pool, the main 1.5" return line again uses a 1.5" 4 way tee to split in to three returns, one of which goes to a slide and is always off unless slide is on. Between the output of the pump and the the PVC going in to the 4 way tee to the returns, there is 10 90's, which I know is having an impact on flow.
I've never been very satisfied with the amount of flow I get through my skimmers. It seems like a lot of stuff will float right by them even when the VSP is at full speed. With my filters removed from my cartridge filter, which I would think would give me an idea of back pressure on the return lines, the cartridge filter reads 18 PSI which seems high.
I've done quite a bit of PVC plumbing before through previous hobbies, and finishing our basement, so I'm comfortable with it. I'm debating removing all the 1.5" plumbing on the equipment pad, which has quite a few 90's on it, and replacing it with 2" plumbing and probably long sweep turns instead of 90's.
Question is.... is this work/cost worth it? Would I see an increase in the amount of flow? It seems like all the 90's and reduced 1.5" at the equipement pad would have a big impact, but before I do all the work, I thought I'd ask to see if anyone knows if I'd see an impact?
