That's how it used to be done! Remember a lot of houses were built before electricity and it's been retrofitted over time.
- doubled112 4y agoA water pipe is bare copper straight to the ground. It makes perfect sense if you think about it. Pretty sure that is how it is done in my much newer than electricity build.
- loeg 4y agoOld copper water pipes, yes. Obviously you can’t ground using a PEX pipe.
- cesarb 4y agoWouldn't it also need a continuous copper pipe until it meets the ground? A pipe being made of copper or iron doesn't mean it's not connected to a plastic pipe or adapter upstream; and I've seen plumbers using a rubbery-looking tape between the threads when screwing two metal pipes together, which might not be conductive.
- finnh 4y agoI just fixed this situation in a house from the 70s. Cable coax lines grounded to a metal hose bib ... which, in the crawl space, switches to PEX about a foot away from the bib. Cable guy installing high speed internet was all "nope!". I think the previous owners just had crap internet and didn't ever get into why.
- sidewndr46 4y agoThe coax shield must be broken somewhere between you and the service provider. "Grounding" a coax to PEX should never make a difference in any way.
- finnh 4y agoI think part of his worry was lightning strike busting their equipment. Unsure about the rest.

A pipe being made of copper or iron doesn't mean it's not connected to a plastic pipe or adapter upstream Right. > I've seen plumbers using a rubbery-looking tape between the threads when screwing two metal pipes together, which might not be conductive Probably PTFE (teflon) tape. The thing to do with oldschool copper pipes though was to braze them together, which is conductive.
- rpvnwnkl 4y agoI think the continuous water still maintains a ground path even in pex
- bombcar 4y agoWater is actually not very conductive at all which is why you need to install ground links if you break into an existing grounded pipe. And the purpose of grounding the pipe isn't to use the pipe as a ground (some very old electrical setups may have done this), it is to prevent the pipe from getting energized by a wire or something resting against it. If the pipe is properly grounded, that'll short out a breaker.
