Water Pipes Grounded

[Guest guest]

Diane,

Yes, they are supposed to be grounded.

The NATIONAL ELECTRIC CODE..states water pipes to be grounded AT the SERVICE

ENTRANCE to the house.

This means that at the entrance, where as in the case of my house, both the

electric panel, and the city

water enter the house via the same wall. This is also where the grounding cables

are to be used,

having been connected to both the electrical main panel and the primary water

line- then, thru a hole

in the wall, the cable goes outside and is then, connected to the grounding

rods.

The service entrance is the wall where your water line connects to the city's

water line. The water meter

- mine anyway, is located at this area in my basement, where my water line

connects to the city's.

Where the problem and emf issues come into play, is that often electricians will

use the water pipes, any water

pipes to ground electric wiring. This creates what is called: " net current " on

all the water pipes thru out the

house. It essentially puts current onto not just the pipes themselves, but into

the water supply running thru-out

the house. It can create a rather large field of unwanted and harmful emfs.

**Before you ask, I have seen the regulated change in the actual book, National

Electric Code. I do not own a copy-

my electrician does. The code used to be, that using the water pipes to ground

was okay, it has, as of a year ago,

been changed. The code book specifically states the water line is to be grounded

AT THE SERVICE ENTRANCE.

Electricians for decades though, have used any water pipes near a new or

modified wiring addition, to ground

to.

I was told new construction grounds them to a grounding rod & not on water pipes

as used to be done.

I believe, tho, Lizzie, there are State codes which enforce this. Here in Pa,

they want water pipes grounded, but I know for fact this is not the case in all

States.

According to the National Electrical Code, just updated this past year: it is NO

longer code for water pipes to be grounded. Code calls for grounding of water

line AT the service entrance (this is where the water comes into the house.)
