What could be wrong if you have no hot tap water?
If you have no hot tap water, you probably have no hot water at all in the house. The would be that your water heater is off, by which i mean the flame blew out and you must reflame it. This is how you do it. At the water heater there is a square grey valve, that controls the gas that goes in to the heater.You must put the valve on top to “pilot”,then hold down. But before you do that, underneath there is a panel, that you must remove inorder to light the pilot. Remove the cover and get a flash light, so you can see. You should see something that looks like a stove pilot, hold the red button down so you can feed the gas to the pilot, then light it with a log lighter aka long lighter. A flame will light if done right, but dont let go of the button. Believe it or not there is a censor that must heat up. Let go of the button slowly. If you see it wanting to shut off just hold it back down, or start over again. Give it time, like 5 mins or less. Then let it go. Bingo your heater is back on
