Hi;
I have a plumber doing a job under the crawl space area. He said that he will use copper pipes but not in area which are hard to get to. There he will use "pegs". I understand these are flexible pipings but not copper. Is that right?
There is a reason why we use copper piping and I fear now that using these pegs is not the same quality and reliability than copper. Can anyone tell us if this is a concern?
Many thanks

The name is "PEX" and it is a flexible plastic tubing. Your plumber wants to get around corners and tight spots be using Pex. I can tell you this. Plastic will outlast copper. I'm surprised he didn't run the entire job in Pex.
Have no worries, the Pex will outlast you. Good luck, Tom

As Tom says, I would have him do the whole job with pex pipe, besides it being a good piping system, it is a big labor saver.
