3/4 pvc to 3/4 cpvc

[Peevee]

When making a connection at a house from the service line 3/4 pvc to 3/4 cpvc. What kind of solvent do you recommend? I run up on this situation this week. I used cpvc glue and it worked. I was just curious if this was the right choice.

I believe there is a universal solvent for PVC and CPVC. If you do not use the universal, I would be suspect of the connection to the PVC. It may seem to be holding, but then fail in the future. Perhaps someone with more knowledge will respond.

I used cpvc glue and it worked.

What kind of coupling did you use? Those two pipes are not the same size, and I have never seen a way to actually cement them together.

You have to transition with a male pvc adapter to preferbly a brass cpvc female fitting.

There is a transition solvent for abs to pvc, I haven't seen one for pvc to cpvc. The best way is to glue a pvc male adapter on. Screw a threaded brass ball valve onto it and then screw a cpvc male adpter in the other end.

I think whenever you transition from one type material to another at least in Virginia, you have to have a mechanical joint.

Can't speak for Virginia,but there is definitely a solvent transition for CPVC (CTS) to PVC (IPS).

Use PVC glue on the PVC side and CPVC glue on the CPVC side.I would avoid that all-purpose adhesive.
