I realize that PEX is far superior to
Polybutylene, but the Shell Oil debacle kept me busy for almost three years, preparing tracts of homes to be replumbed. As a result, copper throughout my home, water softener included. Living in a mild climate adds to my confidence level.
I regularly shore up any leaks in my 401k.
I too remember the Shell oil problem, also remember Aluminum wired home problems.
Cost of labor and materials has set copper on the back burner down here.
Most all spec homes are using PEX.
I gave up on my leaks in ENRON, LU, ORIG, LINN, think I just found one in TRVN.
Like I've said in the past, started out with nothing, I still have most left.
At least I didn't have YRCW, like my friend had.
