I'm replacing my 1 HP Hayward single speed pump with a Hayward Super Pump VS (SP2600VSP). I am also using this opportunity to replace the plumbing of the supply valves into my pump. Here is a pic of my current setup (with old pump):
My question is what brand duct tape should I use to keep my new connections from leaking? jk. I know I have a few issues. For instance the old pump is way to close the wall, I don't like that. I also want to have a longer run of straight pipe before the pump inlet. I have
2 skimmer lines (1.5" PVC)
1 main drain line (1.5" PVC)
I want to be able to select any individual drain, or any combination of the three. A lot of people use 3 way valves. I noticed they typically have two 1.5" inlets with a 2" outlet. One option is to group my 2 skimmers into one 3 way valve, and then connect the output of the skimmer valve to another three way valve along with the main drain. But it seems to me that this gives preferential flow to the main drain. Is that a reasonable assumption? I want to be able to give my skimmers plenty of flow to suck up all the leaves and bugs that get dumped into my pool by neighboring trees. My other option seems to be to use 2 way valves and use T connections. I will gladly accept any suggestions on this topic.
My next concern is that my plumbing uses PVC. I notice the Jandy valves everyone seems to love is CPVC, so that is a bit of an issue. I'm having a hard time determining from online sellers whether the Pentair valves I am looking at are PVC or CPVC. Anyone know where to buy them where it is clearly marked? Maybe another brand I should consider?
Also, Is it a good idea to use slip fittings? Possibly around the sand filter inputs/outputs... anywhere else? Any better quality options?
Thanks in advance to anyone responding!
