No hot water pressure in kitchen

[jeranderson]

My kitchen sink and dishwasher are getting little hot water with very little pressure.

The faucet is a single handle faucet and the pressure reduces dramatically when pushing the handle to hot. The dishwasher is only about 2-3 months old has worked fine until now. A little water trickles thru but not near enough to run properly and clean the dishes. I disconnected the hose from the dishwasher at the compression valve and water is coming through there, though I couldn't tell if the flow was normal.

It's a small house, but the hot water heater is on the opposite end as the kitchen.

What could be going on here? Since it's both the sink and the dishwasher, I'm not sure where to start. Any help is greatly appreciated!!

I always start with the quick cheap easy approach. Look for particulates in the faucet aerator and go from there.

Update:

Took everything apart and there was a lot of gunk and mud in the lines near the faucet and dishwasher. I replaced the hose to the faucet and it works fine now. The dishwasher needs a new inlet valve.

So, question is, why is there so much stuff in the hot water lines? Is that normal? Time to replace the hot water heater or just drain it?

Every other faucet seems to work fine, but I guess everything got pushed to the end of the pipes where the sink and dishwasher.

"why is there so much stuff in the hot water lines? "
Could be:
- water source to the house.
- your WH
- your pipes
- your stop valves and connectors' washers.

"Is that normal?"

Small amounts of junk could be expected and be controlled with water filters. Large and frequent amounts of junk indicate more severe conditions that should be solved.

"Time to replace the hot water heater or just drain it? "

How old if your WH?
Have you ever flushed it?

I'm assuming the water heater has never been replaced in the house, so it's about 15 years old. I flushed it once about 5 years ago.


One note, the fire department comes by about once a year and checks the hydrants. The water is always dirty following that, so that probably doesn't help.

Thanks for the follow-up.

I think a good whole house cartridge filter for city water is a good idea. It should have 3-valve bypass or built-in bypass.

I am not saying your kitchen gunk was from the incoming water. That may have been decomposing hoses at the sink or WH.

Note that you should use correlated copper or stainless at the WH if you have flex lines.

There are many benefits to having a tankless water heater and one of them is you don't have to worry about crap floating around in your hot water tank. However, most likely you will have to increase your gas line to the heater if you go this route. I installed one 5 years ago and haven't had a single issue with it. I would never go back to a tank again - cleaner, unlimited, cheaper hot water.
