Wouldn'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

Wouldn'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.

The thing to do with oldschool copper pipes though was to braze them together, which is conductive.
