We have a 2-story home with hot water tank in the attic. There are two faucets in the house, one on the ground level and the other on the upper level that have very low hot water pressure and they appear to be on the same water line - one right above the other. The cold water in these faucets works fine with normal pressure. The problem started on the bottom floor 6 months ago in the kitchen. Now that the upper level hot faucet (master bath) has bad pressure, too, the lower level hot has virtually zero water coming out now. All other faucets upstairs and down have normal hot and cold pressure available.

What material is the water line? I think I would shut off the water at the angle stop in both instances first and use a different water supply line aimed into a bucket to see if there is pressure past the stop. If there is, I would replace the supply line if it is old, or flush it if it is newer, then disassemble the faucet and flush out the hot water side and back flush the cold water through the waterway. If there isn't much volume coming out from the stop, shut down the water and bleed off the pressure then remove the stop entirely. Hold a bucket in front of the stop and have someone turn on the water for 2 seconds. If pressure blasts out, replace the stop; if it doesn't, you have a problem with the water line.

Thanks for the response. I will give it a try. Really hoping that fixes it.
