My natural gas water heater was down for a few days (bad ignitor electrode). After starting back up I noticed a sound which I could best describe as a drip extinguishing a flame. Looking through the window it appears something is going on. See video here: https://www.youtube.com/watch?v=lezAmg7RHZs
I read that non-defective water heaters are often returned because condensation is mistaken for a leak. It is very cold in the basement where the water heater and I see no water/condensation around the heater itself. Is it normal for this to happen during the first warm-up?
Hi, That sure does look and sound like condensation. It’s far more common with a cold start, which you had. By now, the tank has heated up and even when you use water and the tank reheats, you should be getting little or no condensation as it’s starting out much warmer. If it were a leak, you would see water on the floor. You can get this after a big load, like tub filling, but otherwise condensation like this is rare and not worrisome.
