I have a bathroom faucet that has very slow pressure coming out of the hot water when I turn on the faucet. The Cold water comes out normal but hardly anything comes out of the hot water. This is the only faucet in the house this is happening and I did make sure the hot water shut on valve is turned on all the way in this faucet. Please advise how I can fix this problem?

Oaklander - hi, it sounds like the hot water valve stem needs repaired. I'm guessing you have separate hot and cold water handles on this faucet. You should be able to cut the water supply off to that faucet and then disassemble the hot water handle to get to the valve stem. The big box stores carry replacement parts and valve stems for a variety of faucets. You may want to swing by there first to see what they have and to ask one of their associates; be sure to take the faucet brand name with you.

I had this same problem on the two bathtub faucets in the house I bought last was the hot water valve stem in one and the cold water valve stem in the other. Both faucets were Alston brand. Replacement stems ran me about $7 each and all I had to do was remove the old and install the new.

If your faucet is a single handle unit then you might need a new mixing cartridge or there may be something that simply needs adjusting. The expert plumbers who frequent these boards (I'm not one of them!) can offer more help if you post back with the brand name, type of faucet (e.g., tub, sink, etc.), number of handles, and how long this has been happening. Good luck! Jim D/West Point, VA

There may be other causes of low hot water pressure on the faucet.

If your line is blocked at the angle stop or supply tube by debris, you can clear it by removing the angle stop and supply tube (after shutting off the hot water supply, then flushing out the lines.

You may have a blocked galvanized line if the piping is old. This is due to rust, corrosion and calcium buildup. If that is the case, you will have to replace the line.

Good Luck
