PEX pipe

[DickWilson]

Bob; I would agree on the polybutyl pipe problems, but PEX has been used in europe for almost 20 yrs, and has been used here for about 15 for the wirsbo radiant heat applications. Copper also has problems with respect to water acidity and velocity of flow. My concern is to reduce construction cost and was rather surprized to have so much trouble finding plumbers there who are familiar with it and willing to use it. I'm in contact a couple of plumbers now who work with it and will see what the relative cost comparisons work out to be. One of my concerns with PEX is its limited permiability and use in contact with Termite treated soils and HI-Bor treated wood, which is one of the reasons I wanted to talk to a plumber who has used it there. Thanx everyone for all the help

Acid rain is now a serious problem on the big island something to highly consider when choosing what to install.
All kinds of stuff (like fluoride) is getting into our catchments from the volcano emissions.

Supposedly if you have an older metal roof the acid rain will leach out lead and into the catchment it goes. scary.
