Copper pipes vs Plastic

[away]

Peter,
Check to see if the Home Depot rents the crimp tool (both Lowes and HD rent them around here). I would assume the rent for one day is much less than buying it. Get all your pipe laid out, fittings in place, etc. so you can then just blow through all the crimps at one time.

I've heard from several sources that PEX fails due to thermal expansion deteriorating the pipes and loosening the crimps. However, I haven't found any life expectancies for PEX. Anyone know this or at least have a ballpark projection?

I thought some said that mice like to chew on Pex. I don't know ,but I just repaired a pin hole leak in a pex pipe and have no idea how it got there it really looked like some one stuck it with a pin. Whoever was in that ceiling with a needle really pissed me off.

Are you working on properties that you inspect? Or was that your house?

No it was a side job on a forty year old property. That would be unethical. I have no idea when and why they put in pex. Everything else was copper.
