Cost: PEX vs Copper

Does anyone the installed cost difference between PEX and copper pipe when done by a professional?

PEX materials are cheaper, and require significantly less time to install than copper.

Is installed PEX plumbing half the cost of copper? One-third? Anyone have any direct experience with a professional plumber?

Thanks,
Tom

Copper was the most expensive when rebuilding my house. Materials and labor were higher.

Tom,

I'm not a pro plumber but I do a lot of water system repairs in RV's. From my perspective, I would say that you should save between 30-40% using PEX over copper....labor and materials combined for a large job. The savings are much bigger for small repairs like leaky connections and valves.....50-60% there. Hope this helps.

The cost of the materials will be little different either way - there just is not that much plumbing in one of our coaches. The labor should be significantly less with PEX, however.

I cannot imagine a reason to choose copper over PEX in an RV. PEX should be much more reliable and longer lived.

I agree. I recently corrected a mistake that was done when my TT was fitted with PEX (PO). It was a bit of work, working under the rear bath sink. I would not have wanted to crawl into that area with a torch in my hand. PEX also gives you some protection from freeze as the pipes will expand slightly. Copper pipes will split if the water inside freezes.

Plus with copper you have to buy a tube bender and flarer. All that's really needed with PEX 'n Qwest is a tube cutter (the crank-up mechanical leverage ones from Lowes for about $15 are nice) and an adjustable wrench.

A slight disavantage is that can't get as tight curves with PEX as you can with copper.
