So this place was made into a duplex and they forced a hot water heater into a small closet. Maybe I'm not understanding properly but why is there not a hot water Shutoff valve there? The hot water wasn't shutting fully off on the tub, so the valve stem likely just needs to be replaced, not hard.. quick cheap replacement usually... But when I went to shut off the hot water I found this.

Side note, I also found their was no exhaust vent for the dryer a couple years ago, we had to have someone cut a whole where the exhaust was ran, but just sat up against the exterior wall with no outlet. (Obviously a fire hazard). Shit happens, but am I wrong that a shut off valve should be there?

Okay, then yeah, it’s pretty typical to just shut off the cold water feed to the water heater. Pull the cord/flip the breaker, whatever it takes to turn it off… open all the taps if there’s water pipes above it so everything drains, then replace the faulty valve in the tub.

Same concerns though, if the furnace isn’t properly vented you’re going to be breathing carbon monoxide. That absolutely must be corrected, the unit is not safe to occupy and any municipality will red-tag the installation and shut off the gas supply until it’s corrected.

Care to explain more about the monoxide. Is that only if it is gas, or are you saying it could be an issue if electric as well?

[–] DataCrime@lemmy.dbzer0.com 5 points 3 weeks ago (1 children)

Only if it’s gas. It’s a combustion byproduct.

Yeah there isn't a pilot light in the closet, so it should be fully electric

Right… but if there’s a furnace in your unit that isn’t properly vented that’s your priority.
