I have a water leak in my ceiling.I'd rather not tear out the whole ceiling to replace all of the polybutylene.Do compresson fittings work with polybutylene?Can you glue pvc to polybutylene?I can't seem to find polybutylene fittings.Any suggestions are appreciated.
Certainly gluing different types of pipe together is not really something that would be acceptable as far as building codes go.
It probably won't work if the pipe in question is under pressure, you'll end up having a large margine for failure of the glued joint. However, i've seen people glue all numbers of different style of plastic pipe together for drains. Again, i'm not saying its right, but for a drain it will more than likely work.
The pipe in question,is under pressure.After I posed the question I went to the plumbing supply house.They had brass compresson fittings,which I've never seen before.You just push the pipes in the fitting and it holds like crazy.You can't pull them apart.It's holding for now.Only time will tell.
If you have PB piping in your home, I would advise you to do a little research. The material has a history of failures and has been the subject of several lawsuits.
