Re: any disadvantages to Pex plumbing?
Howdy, manifolds sure use allot of additional pipe. The 25 year warranty seems too short for plumbing compared to copper. But the $$$ difference and ease of running pipe is very appealing to me. Check out Dahl of Canada plumbings pex shutoff valves and the UV shielding for stub out with pex instead of copper. I'm re plumbing a grand old home an using the stainless steel crimp rings - one tool to crimp makes the job easy and inexpensive.
Any an all of my comments are just my opinion and not to be confused with facts.
