I just bought a house, and my new washer/dryer is being delivered tomorrow. I have the older style 3-prong 220 outlet, which I know I'm allowed to still use. I also have a 2-prong 110 outlet next to it for the washer, which I don't think I can use. Since I have to upgrade the 110 outlet, I was going to just do both at the same time.
The outlets are located at the exact opposite diagonal corner of my house as the main panel. I had planned to just pull out the old ungrounded 10/3 and 12/3 and replace it foot by foot back to the breaker, ground it, and call it a day - but then I noticed that my breakers main ground runs all the way back to the laundry room, and connects to my main water line which just happens to be next to the washer.
My question, would it be safe, and code, to just run a #10 ground wire over to the same ground clamp on the water line? Or maybe secure a secondary ground bus near the water line, to tie into?
I know the codes need to cover every possible application, but it just seems silly to run $200 worth of new grounded cable back to my breaker, to tie into a ground that literally runs all the way back to where I started.
Thoughts? Thank you!!
