Angle Water Stop riser to sink

2602 Views 2 Replies 2 Participants Last post by  [email protected]
At the inlet side of the riser connection on an anlgle stop, using 3/8" white zurn pex pipe to the faucet. I have been told by different plumbers that a copper insert into the pipe is required to stop crushing of the pipe and by other plumbers I have been told that as long as you use a nylon compression ring you do not need the insert. I see from one manufacturer that if the pex is 3/8 or greater then the insert is required, but not 3/8" or less. Now, when I install the nylon cimpression ring on the pex. It still seem to crush the pipe. Does any one know of any written documentation relating to whether PEX requires a sleeve in the pipe .

Thankyou Just Bill,

I absolutley agree with you relating to the insert, but brasscraft is stating it is only required on pex greater than 3/8". Do you know where I can find that documentation.
