hot water knob wont turn all the way

Hello i'm new to this forum and to doing home improvement things myself.

i have an older 2 knob sink.. here lately the hot water knob wont turn but just a little bit and barely let any hot water out.. when i compare it and the cold water knob the hot water knob when completely shut off is still screwed most of the way out of the sink and the cold water knob screws all the way down to the sink when its closed. so when i turn the hot water on it only takes the knob just a bit of a turn to already be all the way open, but only a trickle of water comes out.. i'm not sure if i'm explaining this clearly.. if you have any more questions i'll check this thread reglularly.

Sounds like it is time for a rebuild of the valve stem, or both of them while you're at it.

First, shut off the water supply to the faucet at the shutoff valves, or at the main shutoff if you don't have shutoffs under the sink.

Take the handle off. You'll have to figure this one out. There are many configurations on the market. Usually it involves screws of some sort, and it is done from above the counter.

Taking the handle off will expose the stem. It will be a brass or plastic cartridge. Some thead in, some just seat in there. That's what needs to be replaced or rebuilt. Before removing it, take note of how it is positioned. Some of the plastic ones have a specific orientation that must be matched when reinstalling new ones.

Take the stem(s) to a plumbing specialty store and ask what to do. They're not overly expensive. The box stores have some, but usually not the selection that plumbing supply stores do.

And depending upon the type/brand, the hot water valve stem will be different than the cold water valve stem, so ask at the plumbing store.
Better yet, take them with you.
Good luck!

Definitely take the old one with you. Here's a link to an article that might help:
