My gas hot water heater is leaking. Don't know if it is a fitting or the tank is breached. It is not the pressure valve. I had to turn off the water feed line, turn off the gas, and empty the tank to get it to stop leaking onto the floor in the basement. It has stopped leaking. I need a service call but it doesn't have to be a night or a weekend because it's now not critical. Also what do you charge to install a new 30 gallon gas water heater? What is the cost of a tankless system?
