Just a word of caution with those..
I plumbed my entire living room and kitchen with them, then went away for the weekend only to come home to a nice flood.
Those pipes and fittings MUST be anchored perfectly inline with each other.
If they are on an angle or the pipe isn't totally square inside the fitting it will leak. Mine didn't leak until the head kicked on and all of the pipes swelled, pulling them away from the walls.
I returned all of the fittings to Home Depot for a full refund and ate the cost of the pipe.
I re-plumbed everything with copper. Still a tried and true method. Not a problem since.
So just factor in the possibility of them leaking.
I have used and specified them for commercial applications and they have worked fine, but for some reason they didn't in our house.
Both my wife and I are architects.
Good idea, but not 100% yet.
