hot water problem


In my kitchen my hot water does not get as hot as the rest of the house, but the pressure is the same. I have a one story house in Florida and the runs are roughly the same distance. Do I just need to turn up the hot water heater or could it be something else?

Do you get very little heat or does it take a while to get hot? If you have a longer run from the heater to kitchen than elsewhere it may take a while to build heat as it pushes the standing water out of your pies. You should check to see if your pipes are insulated with foam wrap. If they are not wrapped , you could wrap both hot and cold.

No matter how long I wait it does not get as hot as the others in the house. The plumbing is ran in attic with vaulted ceilings and can't get to them, so I can't check to see if the pipes are insulated or not. It is a small house and the weather here is warm so I would not think it could cool that much in the run.

My Brother is down there with a similar slab scenario. If your kitchen is closest to the hot water tank, and assuming your pressure is equal in both hot and cold settings in theory your hot water should arrive at the sink there the fastest and it should take longer to build heat further away from the tank, insulated pipes or not. If the kitchen is nearest the tank, just a stab here but you might be having an issue with a mixing valve in your kitchen tap? Is there any other cause for restriction or heat loss below your sink. Is the hot water split off to another area or device. Where is your kitchen in proximity to the water heater.
If you have pipes burried in your slab, the slab could be acting as a heat sink and drawing heat off when the water is not running, but you should still eventually have hot water.

I'm really not sure if the water runs to the kitchen first or last. The dishwasher is connected to that same pipe under the sink. As far as the mixing valve goes, I shut off the cold water to test that but with same results.

Try posting a sketch with locations and perhaps an undersink photo. Maybe some layout details as to distance and direction from tank. There are some great plumbers on this site most days. Someone with slab experience will be of more help.

Some utility sink faucets are bad for crossover.
