I have a double check valve assembly for my sprinkler system, installed by a plumber. I am planning to do all the work after the DCVA myself, in PVC. THe DVCA has a female 1" threaded copper connection on the outlet.
How do I go from that to PVC? Can I screw in a PVC adapter right into the copper (the adapter would be male 1" threaded to female 1" slip).
Thanks.
