I have an issue, just bought a 120 year old home... I was outside playing with the hose with my 3 year old daughter and as I was turning the hose on and off, I noticed something every time I touched the valve...it's LIVE... I was getting a shock everytime I touched it, and I would assume my daughter was too... it's very small....not much power... Directly underneath the faucet is a conduit that is runing electricity from my house to the barn... could that be the problem? or what else could it be... looked at it from the inside and I can't figure out what the problem is. HELP me before someone get's hurt!!!
