I'd like to start by telling you that I am not an electrician, so my terminlogy and knowledge is not up to speed.
In a dwelling that has metal waterpipes used for or connected to the grounding electrode , are metal plumbing fixtue supply lines significantly safer than flexible plastic supply lines which are commonly installed. I realize that a functioning GFCI would provide protection, but how many people test GFCIs and what about locations where GFCIs are/were not required. Is the water itself considered a good enough conductor to effectively trip a typical breaker or fuse. This is not something I care to experiment with.
thanks in advance for any insight
