For those of you that have probably seen everything...
I plan to replace our 2HP Pentair WhisperFlo pump with a Pentair IntelliFlo VS (11018) in the near future. Checking out the equipment pad, I note a problem of not having enough PVC pipe between the existing pump and various connections on the suction side of the pump. Immediately in front of the pump's intake is a check valve, and before that are two Jandy valves, on that controls suction between the spa and main pool, and the second that controls pool side suction between the skimmer and the cleaner line. Unfortunately, the 3-way Jandy valve that controls suction between the pool and spa side abuts the check valve. There is about 1-1 1/2 inches of PVC between the check valve and the inlet of the WhisperFlo. I'll try to get a picture of it if I can figure out how to post it.
I would really like to replace both the check valve and the pump, but not disturb the rest of the plumbing on the suction side. I could just cut the line after the check valve, add a PVC connector and run more 2" PVC. I have to set the new pump back a bit since otherwise the lines to and from the gas heater will prevent access to the control panel on the IntelliFlo, so adding some new PVC plus the twist on connectors will help to scoot the pump back enough for this. But, I'd really like to replace that check valve. Is there some way that I could cut the existing check valve out and add a new check valve without having to completely replace all the plumbing (and two Jandy valves) in front of the pump? Are there solvents one could use to take apart the joint between the PVC and check valve, since at present, the check valve just butts up against on of the Jandy valves?
It's quite frustrating the way they plumbed this!
