My water heater leaks sometimes and not others. I replaced the drain valve thinking it may be that. It stopped leaking for about a week, thought I had it beat then I noticed the leak again. The water collects in the bottom of the water heater pan below the burner and then slowly drips out the orifce where the water heater foot come out of the skin. I can actully see steam come out of the water heater by the piolet door. I checked the pressure valve and dose not appear to be leaking, dose this sound think condensation or do I have bigger problems and if so should I repalce the tank or just try and put a catch pan under water heater w/ a hose to the floor drain like you would on a air conditioner. Thanx, Brady
