None of y’all are plumbers and most of y’all work in IT and it fucking shows.
This is not a case where a photo is required or even all that helpful.
A photo shows that water is running. Is it hot, is it cold, is it lukewarm? Who knows?? Certainly not the landlord.
Probing questions sure would have been helpful. Like is the water lukewarm or cold?
If it’s either it doesn’t matter, the heater is not working and a plumber is required.
Now what if the water isn’t running? Well then the response would indicate that.
“No there’s no water at all when I turn on the hot water.”
Ok that’s an entirely different problem, could be the heater, could be someone turned a valve off.
But even that much information isn’t all that important because no matter what the problem is, or where it’s located, the tenant will not be able to resolve this issue, a plumber is required. They’ll need access to the premises, because water heaters are generally inside the unit, which means the tenant will likely need to be present when the plumber shows up.
The plumber is absolutely not going to show up with a water heater based on what information he can get out of a text. He’s going to come in, and investigate the issue. Sometimes it’s a quick fix, sometimes it’s a problem. Generally the tenant is going to have absolutely no way of resolving it themselves, and generally a landlord wouldn’t want them to.
This is not an IT ticket, it’s a "call a fucking plumber my shits broken " ticket.
