PVC to Qest

Hey, I have a drain valve stuck and needs to be replaced. I need one connection of PVC to a drain line 4 inches. Can I glue a PVC coupling to the Qest line and start there rather than cutting out $20 worth of Qest fittings?

If the question is gluing pvc to quest,then no . Qeust pex is a polybutelene plastic and won't bond to PVC (Poly vinyl chloride).

quest pex is mechanically crimped to a brass transition fitting that provides a pvc coupler if going from Quest to PVC. If you go to a plumbing supply place you may be able to cut the crimp ring, heat the quest with a heat gun and pull the bad valve out if there is enough slack in the pipe. The plumbing place will usually loan out the crimping tool for a short period of time so you can re-crimp it. Without seeing exactly where your working and the way its plumbed this is all the advice I can give. I would advise staying with quest or PEX over PVC in a trailer. PVC doesn't handle vibrations and freezing as well as the quest. Also quest makes a comprestion fitting that fits over the pipe and a nut locks it down, there may be a transition fitting like this and you would not have to use special tools. Good luck
