Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of you situation.
Is the water just not hot or is there no water coming out of the hot side of the faucets? Is the house on a slab? where specifically does she have it? not have it?
So it sounds like she has no hot water in 1 shower and the kitchen sink is that the extent of it? are each of these faucets single handle faucets?
Some possibilities include a crossover from the cold side to hot in a single handle faucet due to a bad cartridge. If she has a re-circulation line on the tank then the check valve at the bottom of the tank could be faulty. Could also be a cross over through the washing machine if the water is turned on to it.
Just come back to this thread and we can pick up where we left off if you have more questions. You can rule the washer in or out by shutting off the water to it. Same with the kitchen sink (shut off the valves under the sink). Shower valves (faucets) that have single handle controls are another possible crossover candidate.
I should mention I won't be online much longer. I'm on the East Coast and my day is about over. If you have more questions and I'm offline you can either opt me out if you need an immediate answer (a colleague will pick up the question) or I'll respond in the morning.
How did this work out?
