I have no hot water pressure in one of my sinks in the Master bath. All other faucets in the bathroom are fine and cold water comes out of the problematic faucet with ease.

I have reviewed some of the similar posts and opened up my single handle faucet to clean the cartridge. The cartridge was spotless.

With the faucet opened up/taken apart, I turned on the hot water valve under the sink and nothing came out - not even a trickle. I turn on and off the valve several times hoping that this would loosen something up. I turned on the cold water valve under the sink and the cold water came spewing out without a problem.

Any thoughts on where the blockage might be and how I can fix it? Thanks much.

Do you live in an area where the pipe may have frozen? (cold climate)

IF not, then you can remove the line that goes up to the faucet and see if you get water coming out after the shut off valve. Turn off the main water and then have someone else slowly turn on the main water after you remove the line going to the faucet. The shut off valve may have sediment clogging it up.

Mike, He has cold water pressure so I doubt his problem is a frozen pipe.
My guess would be a clogged seat in the angle stop.

Chappy, How often do you flush your water heater? Try this. Shut off the water to the angle stop at the cold water shut off to the heater and open up a hot water faucet to relieve the pressure. Shut the faucet and remove the hot water angle stop located under the cabinet. Check the inlet of the angle stop for trash. Now hold a bucket in front of the open pipe and have someone turn the water heater back on for a minute. You should have a strong stream. Check the supply to see if it's clear and reassemble. If that don't get it click on back. Regards, Tom

The pipes aren't frozen and it is just this one faucet. The cold water runs fine - the hot water doesn't run at all.

I have noticed that the hot water has been losing pressure for awhile though. We don't flush the water heater as often as we should (about once a year). I am not very handy, but I will try - otherwise it will be time to call a professional...

The angle stop was clogged which caused there to be no hot water pressure (actually clogged enough to be no hot water).

I cleaned out the angle stop, blew out the gunk in the pipes and reassembled my faucet. Now I have a small leak problem and I can't figure out why it is leaking from where it is. I was hoping I could tap, once again, into your fountain of knowledge. Here is the problem:

When I turn on the faucet and look under the bathroom sink to see from where it is dripping - water is dripping out of the hole cut out for the drain stop (please excuse my terminology). What I mean my drain stop, is the thing that you pull up behind the knob for the faucet to close the drain.

I have a standard one handle delta bathroom sink faucet (the kind that looks like a big crystal door knob), and the "drain stop" is directly behind the knob.

Any thoughts on how water could be escaping through the cut out for the drain stop underneath the sink? Could I have mis-assembled the faucet?

Any help you could offer is really appreciated. Thanks so much, Tom. You saved me a fortune!

Hi Kelly,

Glad you now have hot water. The leak that's dripping through the "drain stop" is coming from the top of the faucet. Go back and tighten up the cap and cam assemblys. Good luck, Tom

I was the weirdest thing - it happened to be the aerator. That was the only thing that I hadn't put back on the faucet yet. As soon as I put that on, the leak stopped.

Thanks so much for all of your help! You saved me a fortune and kept my husband from blowing a gasket over an unexpected bill. I appreciate all of your help. Thank you again!
