bonding of water

[winker1969]

in a single family dwelling I drove two ground rods because the house water pipe was plastic until the termination of each outlet. ie. water heater, sink, toliet, etc. at that point it changed to copper pipe but no part of the copper pipe is in the slab or in the ground. According to the NEC am I required to bond the water? Please remember that 99.9% of the water pipeing system in this house is plastic "peix".

Re: bonding of water

250.104(A)(1) says that you have to, depending on how you define a "water piping system".

As an inspector, I would never dream of requiring it.

Just my humble opinion though, and your AHJ's may vary.

The NEC requires METAL water piping to be bonded, not plastic water piping!

How would you bond it? Run a ground conductor around to the supply on each fixture? What purpose would that serve anyway. It's unlikely that any particular piece of pipe will become energized. This isn't a continuous metallic system, it's plastic.

Remember the if in that sections. If likely to become energized.

The only other way would be to use a high concentration of iron in the water.

Washington State does not require isolated metal plumbing stubs outs to be bonded. The AHJ cn always require it. but in Washinton state its clear what does and does not have to be bonded.
