What is the purpose of a cold water ground?
Plumbing System Grounding Metal pipes are required by code to be electrically grounded, and this is normally done by grounding the cold water inlet pipe to the home. The water heater creates a break between the cold water pipes and the hot water pipes in the home.
Can you ground to cold water pipe?
Popejoy, a licensed electrical contractor in Sacramento, California, replies: To answer your second question first, no, you can’t grab a ground from a cold-water pipe. See 2002 National Electrical Code sections 250.130(C)(1) and 250.52(A)(1).
Why is copper water pipe ground?
Historically, the home’s copper water pipe system provided a safe ground for the home’s electrical system. The plumbing system was grounded because its metal pipes extended a long way underground. Changes in the way homes are plumbed required adaptations in the way installers ground plumbing systems.
Can you ground to copper water pipe?
Water pipes made of copper or cast iron were favored as grounding devices because they typically extended at least 10 feet underground from the point where the pipes entered the home to the main water line.
Can I ground to a copper pipe?
The copper pipe in your house should be bonded to ground, but should not be THE ground for the system… using the piping as a ground can end up dangerous to anyone that may do some plumbing work.
How do you tell if your pipes are grounded?
A cold water pipe can be used as a ground, IF, it is metal the entire length, and goes into the ground. You can also install a ground rod and use that. If your electrical panel is grounded to a ground rod, you can tap in there. If its grounded to a water pipe, you can attach to the water pipe.
Is there a cold water pipe in the ground?
To make a long story short, it turned out the ground / ground grid was connected to a cold water pipe that exited the building on the same floor, and ran half way down the building towards the ground. Once in a while a taxi would stop below the pipe and pick up a passenger.
Can a hot water line be connected to the ground?
These days a lot of the water pipework is plastic and I don’t think that you can guarantee that hot water pipes are connected to ground. All metal pipes should be connected to ground. The previous poster is correct. First, one must make the assumption that all of the water lines in question are metal–normally copper or galvanized steel.
Why is there a copper wire attached to this water pipe?
In an apartment environment, the electrical inspector should assure that all commons in the electric panels in the apartments, are tied to an independent building ground stake hammered into earth ground, and not to the water supply.

Where is the ground wire for a water heater?
The second “ground” wire runs from the ground/neutral bar out through the wall, and attaches to a buried rod at the service entrance. (phone, cable, etc are also tied to this rod) There is a jumper from the service side over the meter. There is a bond between the gas piping and cold water line at the water heater.

Can a hot water line be connected to a ground wire?
Grounding with a Cold-Water Pipe The service panel ground wire might lead to a cold-water pipe, which is connected to supply pipes that lead deep underground. The connection must be firmly clamped. Hot-water pipes are not acceptable for grounds because they run only to the water heater, not into the earth.
What kind of pipes are used for grounding?
Changes in the way homes are plumbed required adaptations in the way installers ground plumbing systems. Water pipes made of copper or cast iron were favored as grounding devices because they typically extended at least 10 feet underground from the point where the pipes entered the home to the main water line.
What kind of pipes are used for hot and cold water?
CPVC Pipes. Like PVC, chlorinated polyvinyl chloride (CPVC) is a plastic pipe that carries water supply both above and below grade. However, CPVC withstands greater temperatures and pressures than standard PVC. Therefore, manufacturers rate CPVC suitable for use in both hot and cold water systems.
