My pump/filter/heater piping and fittings are black plastic (mostly 2") and incorporate black Pentair/Compool 3-way valves. The installation of the system as new was in 2001. The only markings I can find on the fittings, but not the pipe (short sections), is the designation "PVCI" and SCH 40. I am about to do some retrofit to incorporate a new pump. No existing unions at the pump, so I have to cut it out. [yes, I will install unions with the new pump.]
All the fittings I can buy locally are white PVC SCH 40.
I have trouble finding any references to PVCI.
Is PVCI compatible with white PVC?
Any particular PVC cement I need to use? e.g. regular PVC cement or all purpose cement?
