Kitchen sink, hot water pressure is terrible but the cold water is fine. What's the problem and how do you fix it?

I need more details on how to fix it please. Thx

Is the hot water being used elsewhere in the house? I have that problem in my house.

You have some crud blocking the hot water port. You need to take the hot side apart, or a single knob, and clean it. Shut the water off, remove the center of the knob, unscrew the screw, pull off the knob, and losenthe nut under it. If you need more details, post back.

You should check your angle stop, under your sink.The left side is your hot sypply line maybe its not turned on all the way?

From an email: ''I took apart the hot water knob and cleaned it, I still have the problem of the water trickling out with no pressure. Now what do I do? Please help.''

OK, you need more details. It is not the knob that needs cleaning, but the part behind it. There should be a nut near the base of it, or sometimes it is mostly round with a couple of flats for a wrench. Unscrew it, and look for lime and other crud behind it. Sometimes putting a towel over it and turning the water on and off right away will flush stuff out. If the cartridge seems to have junk in it that won't come out, it may be best to take it to a hardware store and have them pick one out to match it.
