Almost as easy as running electrical wire.......after using it, I can't believe I ever wasted so much time sweating copper.

I think you'll like it, Kev....

 

I was looking at doing it in a concrete floor in a grid for radiant heat. Seams to be what a lot of builders are using. The builder I work for uses it.

 

I see they have some other PEX recommended for the heating projects....cant member the details but its on that website

 

Depends on your water if you have very harsh water like in Socal it won't last but a few years then you will have thousands of pinhole leaks. I don't see it ever lasting as long as copper, but maybe long enough you can justified replacing it in 10+ years.

 

I've never heard this before...thats scary cause its all under my house slab and in the walls... 7 years old now.

 

Any evidence on what causes the leakage?

 

:pc:

 

Are you sure your not referring to the older Polly-B and not the I-Pex?
I have yet to hear of a failure with the Pex pipe, a few problems with poor install procedures but not the products fault. The stuff for in-floor slabs is different than just the regular stuff.

 

I agree. Pex will stand up to alot, provided the installation is done correctly. Make sure that you treat the fittings correctly and you should be fine. Are you gonna be on well water or city water? Like any other piping, if you have excessive minerals in your water, it is gonna affect the life of the pipe and fittings. If the water has a high mineral count or high TDS (total disolved solids), you might consider a softner.
