Gas water heater is leaking from the upper valve
I have a natural gas water heater for 8 years, and never had problems until now. This morning I have found a puddle of water under the water heater.
I spent some time investigating where this water (hot water) is coming from and I have noticed that it is dripping from the tube coming out of the valve installed on the top/side of my gas heater.
What causes the overflow on a water heater to drip?
Is it a time to change this valve?
How to do it?
