Low Hot Water Pressure


Currently I am having trouble with the hot water coming out of our kitchen sink. It is coming out at a lower pressure then when we turn on the cold water. Do you know what might attribute to this? All other sinks have no trouble releasing the hot water at full pressure. I'm really confused and would appreciate any advice. Thanks!

It sound as if you have some blockage in the kitchen hot water line. Check it from the faucet working back to the hot water tank or whatever type of heater you have. Could be something in the line, but, usually ends up close to the faucet. Hope this helps.

It sadly was not just the faucet. Just got done detaching both the hot and cold water tubes from underneath the sink. I checked the water pressure coming out of hot water tube and it was significantly less. So, does this then mean that somewhere within five feet of tubing (from the back sink to kitchen sink) there is a build up or blockage? If so, what is the best way to unclog it... Do those advertised solutions that you pour down the drain actually work?

How old is your house? There is a pressure pump (hand not auto) that you can attach to the faucet. You pump so pressure onto the line (20 - 30 psi or so) and then release the pressure. The sudden shift rattles the pipes and can shake any corrosion that could be causing the blockage loose. This is more of old galvanized fix.
For copper you can try the same thing, but be careful on the pressure.
Before you try that you can also check the shut off valve. Those do go bad too

Jester,
I would be careful with some of the chemical claims. If you feel confident, you could replace the line from the heater to the sink. If not, you might want to call a plumber. If it isn't in the line, shut of valve (if you have one installed) or the faucet, the blockage would probably be by heater outlet. This is where a plumber comes in. It may be money wisely spent.

trace the hot water line to where it ties into the main line.the problem should be between the faucet and the main if the rest of your hot water faucets work fine.

Are both lines at that faucet the same size? If the hot water line is smaller, there is your answer.
