Question DetailsAsked on 5/2/2011

Has anyone replaced galvenized pipe with PEX instead of copper?

The galvanized water pipes in my 28 yr old home need to be replaced. It looks to me as though the flexability of the PEX pipe should make the job much easier and also need less cutting of sheetrock to install the vertical sections.

First you will need to check with your local building code. Not all areas are allowing this new system to be used yet. Second, while it may appear to be easier to work with rather than copper, PEX has its own draw backs. The tools are highly priced, the fittings are high and you must find someone who has alot of knowledge with this stuff. This system is not for average home owner to put in. PEX is generally being used in new construction. Any time you take an already built home and switch the plumbing system, nothing will be easy, what ever you use.

I recently replaced all the galavanized pipes in my home with the newer PEX flexible pipes. My friend, a union pipefitter, recommended that I think about two things when making the decision between copper and PEX.

1. How long was I going to stay in the home? He mentioned that PEX was relatively new product, so it's long-term durability is a bit unknown in real world applications. I'm not sure how long PEX has been around, but his argument made sense. If I was staying in it for 20 years, I'd probably want something more durable. But, since it's my first home, and I'll likely sell in less than 5 years, PEX made more since.

2. How much did I want to spend, and was I interested in improving overall resale value? Copper is much more expensive in terms of material and labor, as I'm sure your research has found. While having a proven material like copper could improve resale value of the home, it was definitely going to cost more upfront.

Ultimately, I went the PEX route. I had all the lines replaced in my 1,600-sq-ft home (one BR, two BD) in under 8 hours by one licensed plumber, all at a very resaonable price.
