Pex Pipes (by Roy [AL]) Posted on: Jan 6, 2010 6:51 AM

It is 12 degrees right now in my NE AL town. I am sure eevry LL is wondering if the water pipes (usually galvanized metal) under their SFH's or multi's can withstand these frigid low temps. I guess will all find out when the thaw comes.

In the last 5 years, every plumber I have hired has used Pex Piping when installing new water lines for my houses. I have one house that was completely re-plumbed with Pex piping.

The plumbers here tell me that Pex will flex under freezing temperatures and I should not worry about frozen pipes busting with Pex. The water will freeze inside the Pex but the pipe should flex and not bust when the thaw comes. I sure hope this true.

What experience have you all had with Pex Piping? Does it actually do what the pro plumbers claim? Is Pex piping used in Northern states in new installations which have to meet strict plumbing codes?

Upstate NY, yes, PEX is the best option. My husband was so happy to find PEX, he says it's so much easier to work with and much better handling the cold/frozen weather.

With several days with lows 10+ below zero, I had 2 places freeze up, I plumbed both with PEX 2 or 3 years ago. Thawed them out with out a problem, although I was concerned about the brass fittings.

I hear lots of people prefer pex the from wirsbo (sp?) that uses the expanding connections, no crimping/no metal fiting to worry about. I'm going pex as i replace stuff just for this reason.

If Pex is not busting in the Northern states, then I can breathe a sigh of relief down here.

On Friday night, we have low temps in the single digits in the forecast.This is a rare situation for Southern states.

I think it was Radar that tested the PEX a few years ago. He took several sizes of PEX about a foot long, filled them with water, and crimped a cap on both ends. After repeatedly freezing and thawing in his deep freeze, none of them leaked.

I use nothing but PEX and have never had a single joint leak. Our church has some PEX that freezes almost every winter and has never burst, it's been in place around 10 years now. --141.129.x.xx

The pipe will withstand the expansion of freezing. Faucets and fittings still could burst from the pressure within them. Fittings less likely to do so. Best to shut off the supply valve and open faucet to relieve pressure. Commodes need protection or to be empty. --66.226.xx.xx

I'm a new home builder in NJ, Yes I will only put pex in, for cost, time & cold freezes (not that one of my new homes would freeze). With Pex I don't worry about the minerals in the well water eating it, like I've seen at times with copper.

George in NJ,

Is Pex used only for water supply lines? How about drain lines? Does PVC still get the vote on drain /waste lines?

Pex Pipes (by Paulio [PA]) Posted on: Jan 6, 2010 1:14 PM

Pex can expand to 3x it's original size without breaking.

Pex Pipes (by TIM [IN]) Posted on: Jan 6, 2010 3:52 PM

PEX for water supply, PVC for drains.

PEX does rock. So much easier to work with. I still don't understand why Mike on Holmes on Homes still is using copper when he remodels a place. Anybody got the answer?

Pex Pipes (by Virden [OH]) Posted on: Jan 6, 2010 7:02 PM

The copper makes a durable vertical pipe, prolly used in every home built after the Korean war, PEX just like cpvc or copper must be fastened every 5 feet if you get an inspection and the inspector can pull the pipe you just failed around here and must now have re-inspection with the drywall off.
