Thanks man...I figured as much.
It's a 40 gal short gas water heater.
It's in the garage on a stand and the exhaust bends right into the exterior wall to the outside.
The first dude was like, we can get rid of the stand and get you the tall one. But we gotta install an expansion tank. They gave me a total of over 2800.
The second plumber was like, they don't sell the short ones anymore but the stand is mandatory to meet code. A tall is too tall for our garage on top of the stand so to adjust the exhaust pipe and add the tank, it will still run over $3000. Then he tried to sell me on a tankless for over 5k.
I'm like...come on man...
Granted I've seen shorts in big box stores for around 5 or 600.
I'm gonna call some indenpendent plumbers in a few. I would do it myself but the way this one, the exhaust pipe seems too big and they have it fit all the way down over the exhaust on the tank. Granted, this has worked fine for almost 20 years but not sure if I would be able to do the same with a new tank.
