Have a small leak in hot water tank. Not sure if its on the tank or a connection hose. Looks like it is coming from underneath. How hard is it to install one your self.
How old is your tank? when mine was 15 years old I thought it was leaking and needed to be replaced. when I looked in the back I noticed 2 plastic nuts as the previous poster mentioned. I put some paper towels under the nuts to determine where the leak was coming from. Several hrs later I went back and the paper was wet. After tightening them again no more leaks. This happened when camping in very cold weather below freezing.
