My layout is in the basement of a house built in 2005. With tmcc signal using the ground wire of a houses electrical wiring, there is very little wiring close to the layout, but there is a lot of copper plumbing overhead. For some reason the plumbing is not grounded to the breaker box in this house. More then likely I believe they didn't bother because the house's water supply comes into the house through a plastic pipe coming from a drilled well. The only ground I see is a ground rod driven in the ground outside below the meter. My thoughts were to run a ground wire from the steel well casing, which is about 25', to the point where the plumbing changes from plastic to copper and then a ground wire from the closest copper pipe to the breaker panel. My concern, is there any safety reason the plumbing is not grounded to the panel in this house? There are large oak trees near the well and maybe lightning striking one of them would energize the house's plumbing. My question, will the tmcc signal even use the plumbing if I do this? I do have a whole house surge protector I can add to the panel.
