expansion/transition fittings pvc??
when i am making the transition from rigid threaded pipe to pvc/cpvc do i need to put some sort of expansion fitting between the two or can i just go male pipe to female pvc/cpvc?

or does the expansion fitting just apply to the hot water pipe (cpvc)?

or did i just make this dilemma up in my paranoid head and i should just get on with it and put the pipe together?

LOL:D , now you sound like me. There's nothing wrong with making sure, but there's no reason to put di-electric fittings between iron and PVC. I don't even know what expansion fittings are (not that they don't exist...I just HOPE I've never needed one...:rolleyes: 'cause I didn't use one..'cause I, personally, had never heard of 'em)

Also, you might keep you're posts on the same thread, makes things less confusing to new readers.

If they're a MOD around, and if you see fit, maybe we could get these merged? The other title is "Can Water feed pipes be PVC" or something like that. Same OP, and I think the topics are related

I think he might be talking about compression couplings like the Dresser coupling. I've done alot of old pipe with plumbers and as far as i know pipe thread is pipe thread is pipe thread. Of course sprinkler parts can only be used for that purpose etc. I think the dopes are almost all mixed use. >I hope we didn't run off the plumbers by answering questions we shouldn't have. I'll stop if they would come back. HS..

thanks for the knowledge.

as far as consolidating my posts, i wasn't sure about it. i thought that since my original question had been answered, no-one would go back and check the first post even if i had new questions.

i'll keep them all together in the future though, thanks again

No problem, but most of the regulars check anything new, even in old threads.;)
