Hey all,
I got back from a few days out of town and my hot water wasn’t working.
The ventilation was blocked by over 4 feet of snow that drifted alongside my house completely blocking the exhaust vent.
Make sure to do a walkaround and check your laundry and exhaust vents!
Also make sure that your gas meter (if you have one) is accessible. If the gas needs to be shut off in an emergency, that’s where they do it from.
