Hi, I posted this on another person’s thread but probably should have started my own, sorry for any confusion.
I spotted what I think is rust when investigating a noise coming from my new Bradford White gas water heater (installed 9/30/21). I saw it through the vents at the bottom of the outer shell. Is rust on the exterior of the tank something to worry about? It looks like it’s along a large seam. I’ll have my plumber come take a look, but wanted to ask if anyone has seen anything like this on a new water heater before? There is no sign of any water dripping/leaking. Thanks!
