Copper or PEX (and which PEX connectors)
 
Hi

So i am going to be redoiing a old house (1000 sq ft), i like copper, has a nice "last a long time" feel, however abit of a nightmare if 1 connection leaks for the first time.

So, being i like to look at new ideas, i saw "pex", read about it, looks nice, 1/3rd the price for piping, tools are expensive.. however this leads to a few questions from those that have used it...

I wont be going down the manifold "homerun" route, prefer 3/4 to kitchen, 3/4 to downstairs bathroom idea... thing is...

Ive read alot about "blow offs", ive seen it in europe, this never happens to copper, ive read about having washing machines on PEX results in hard water stops so it stresses the connection and BANG, water leak.

So.... whats the deal, is pex nice but a pay off is a risk of a connection blowing out?

Copper will take way longer to install, but then the tools for PEX might pay for this time alone..

There seems to be a few connections methods, the SS compression ring (small area thats "crimped", i hear these are a bad idea, then the copper complete ring version which seems to be the more stable version.

Theres another "expansion" connection, not sure what this is, tools for that are $300-400 though.... think that would pay for time to do the whole house with copper....

Ideas please, i do like the idea of PEX, easy to install, just the terminations, all connections will be hidden so i cant really check them.... if its not as stable as copper not sure i want to use it.

I hear though here, vertical copper is fine and doesnt leak, not sure what thats about though....

Input please :)

Many Thanks

Try searching for "pex tubing", you will find dozens of threads. "Pex" alone produces no results.
