Hello everyone. I have a plumbing question about hot water in a 2nd floor laundry room. We recently bought a 9 year old house (that has a brand new water heater in the basement). The water is plenty hot in both the kitchen and half bath in the 1st floor above the tank, as well as in the two bathrooms on the 2nd floor (one basically above the tank, the other about 35 feet away after getting up to the 2nd floor). In the 2nd floor bathroom sinks and showers the water is still plenty hot - granted it takes a few seconds in the close bathroom and a little more than 10 seconds for the farther away bathroom to reach a hot temperature.
My problem is in the laundry room on the 2nd floor where the hot water going into the washing machine is luke-warm at best and has very low pressure. And the faucet coming out of the wall is nowhere near hot to the touch when water is being drawn into the machine. The washing machine is at the opposite side of the house from the tank, about 45 feet from the tank once you're on the 2nd floor. The dilemma is I do not know how the hot water is getting to the washing machine, so this is the next step, but I was looking general tips on things to look for as a possible culprit.
I tried looking through the forums with the obvious keywords, but surprisingly didn't find a discussion on getting hot water in 2nd floor laundry rooms. My first thought from watching Ask TOH episodes was it might be a problem with the anti-scald valves in the 2nd bathroom's shower if the plumbing in the two rooms are connected. But since the water seems plenty hot there and the pressure seems fine, the problem is likely elsewhere right?
I am trying to figure out what to try next. Is there simple way to figure out what pipes are feeding the laundry room? Does this sound like it is beyond anything a DYI'er can fix besides cranking up the water heater and trying not to scald myself in every other room or the dishes in the dishwasher?
Thanks for your help. Hopefully there is still something I can try to find the source of the problem at least!
