In response to Re: CPVC to Copper
There are no compression type connections that can be guaranteed to be "safe" in an inaccessible location. And the first two would be definite "no-no's" to my way of thinking. : Hi, : I need to connect new CPVC supply lines to existing copper in a space which is only accessible by tearing up the floor. The flooring is torn up right now to put the new lines in, and I only want to do this once. Therefore, I'm looking for the most reliable, leak-proof option for making this connection, as long as it doesn't involve a torch (this would not be safe in that confined space.) So my choices are: : 1. The hand-tighten grip-style mechanical couplings : 2. A similar wrench-tighten grip style coupling (looks like it's made of milk-jug type plastic). : 3. A double-compression connection with a threaded brass fitting in the middle. : Has anyone had any experience with these types of fittings? Which is the safest bet for an inacessible location? : Thanks, : ~Joe G~
