Replumbing with PEX

[em14]

I have some of this in my house and it appears that I'm getting a pressure drop with it that I don't have with the copper. I have not had the time to see if this really a correct accessment on my part or not ..(there could be some other reason ) ... What kind of pressure lost is associated with PEX compared to Copper ... and what is the difference ....
Thanks,
Leo

Unless the inside diameter of the pex is less than the copper there should be no pressure drop compared to copper, to the contrary flow should be even greater due to not having any 90 deg connections.

I agree with you and that is what I would have thought ... so I just checked and found the mat'l I had thought to be PEX was not PEX .. instead it is a stiff plastic. This is on a sink feed line and I think that the diameter is to small and that is causing the reduced flow and in this case, pressure lost ... I have replaced some with copper feed lines and that does much better....
Thanks

Re: PEX tool

Pete,

That is a great looking. I have read about PEX in the past and it is interesting to hear some first hand experiences. Sure would speed up the plumbing rough in on new construction. With an older home like yours it had to save a lot of walls that would have been opened up to install copper.

If anyone is interested, Fine Homebuilding magazine has an article about PEX in the issue that I received today. (March 2003, Issue 153)

Re: Connection with copper line

This particular line froze last night. The PEX swelled up and held. The copper line split in the middle. So much for my theory that short runs of copper were okay!

Pete, did you mean to attach a pic?

Hazmat -- Nope. It was in reference to the pic posted on 01/23/03 06:16 PM. Same line in that pic.

Sorry to hear that, Pete. I guess all you northeastern folks will be glad to see Spring this year.

Re: Connection with copper line

Seasons in New England are a little different than other places, Bird. Before spring comes Thaw, then Mud, then Bug Season. Spring comes around mid-June.

I never understood Vermonters who take vacations elsewhere during those wonderfully snowy winter months. If ever there was a time to be away, it's the transition between Mud and Bug seasons!
