1. Instructions say to use CPVC glue. OK. Do I use the purple primer as well?
2. Must I use the inlet as the "inlet" ?? or can it flow both ways? Another thread talks about reversing the cleaner line for various types of cleaners (pressure and suction). I'd like to try that, so I have a 3-way Jandy Never Lube valve that I want to hook up the "inlet" to the cleaner line and one "output" to the pump and the other "output" to the return line. Will it work?
