New house, ( for us), water heater is gas and about 5 years old. When we are
away for days, I turn the well pump off and turn the water heater down to
low. When I return, the blow valve at the top of the heater has let water
escape on to the floor. I put a bucket under it and get maybe 1 or 2 cups of
water. When we are home I never notice it blow off. The bucket stays dry?
Anyone have any ideas?
