I just finished an addition on a residense. After everything was done the folks tell me that they are getting shocked off a faucet in the basement shower. The shower has a concrete base on earth. The drain is ABS. The copper pipe in the house is bonded hot and cold the the panel buss. I checked with my meter from the faucet to the panel ground buss and neutral buss and read zero. When measured from the faucet to the hot side on the panel I read 119 on each. I took off my shoe and put my bare foot on the shower floor and touched the faucet knowing fool well I was not going to get shocked and didn't. They swear they get shocked. Got any ideas? Also let me mention they said they have gotten a shock from it long before we did any work there.
