Default My tenant burned her ass on the toilet

The water flowing into the toilet is really hot, it actually melted the flapper. Im pretty sure that the hot water is backing up from the water heater into the cold water supply. Is a backflow preventor something that I should install or is this a problem with the water heater that may need replacing? Also if its a backflow preventor, is there one specific to water heaters that can handle the heat or are all of them pretty much the same?

Typically there is a mixing valve to temper the water to the toilets to prevent condensation.

Sounds like it has failed, or the cold water feed to the mixing valve is blocked, causing full hot to the toilets.

How is hot water even getting in when the only line to the toilet is cold water?

Need to put a check valve on the water heater, they come with little rubber "backflow" tabs from the factory but are not very effective. More than likely there is a bad balancing valve in a single handle shower valve. A bad cartridge can make all water cold or hot, check the other taps both hot and cold and see if they are working properly.

Did this just start to happen? Or did you just notice this?
Have you installed any fixture lately that might allow the hot and cold water lines to connect to each other? If so, the flush could be pulling hot water from that connection.

Winter is here, and it's cold and boring in Detroit right now!

Guys, rubber melts at 260+. Do you really think a hot water tank could possibly push 260 deg water back up a cold water pipe in to a toilet????

(extra question marks were fully justifiable in this situation)

If you dont have hot water out of your cold water tap in the sink the toilet is plumbed wrong.

That is 99% impossible
Hot and cold run separately.
Now having said that, she looks like "hot ass"

When I feel the pipe it is hottest at the water heater on the cold water side which is why I believe that the water heater is backflowing. As you get further away from the tank the lines are still hot but not as hot. I haven't tried the other fixtures in the house but they haven't complained at all. I turned down the water heater to see if that helps the situation.

Also the water going into the toilet isn't always hot. Possibly only when its been sitting awhile without being flushed. I checked it today and the the first flush was scolding hot and subsequent flushes were cold.

The water heater has a check valve like this one. Do I need to replace it?

Water expands when it is heated, with out a backflow it could back up on to the cold side. Depending on how longbthey are gone without using hot eater and proximity of this toilet to the water heater it is possible. Sounds like you may need to turn down the t stats on the water heater, install a back flow and possible an expansion tank. All is relatively easy to install

I would think that the water heater could not furnish hot enough water to melt anything in a toilet

Very much a yankee thing. Up here our water comes out of the ground at 50 degrees or lower. As you might imagine there's some attention that needs to be paid to condensation.

This is a real problem, the guys at the plumbing supply store were laughing at me when I walked in with a melted flapper. Said its the worst they've seen, I wish I would've taken a picture of it before I tossed it. This was a couple weeks ago when I thought the pipe was being heated by the furnace it passes by but I insulated the pipe and investigated further today and I'm pretty sure the hot water back-flowing from the water heater.
