Plumbing question

[Clarence Martin]

Woke up this Morning , and the hot water from the Kitchen faucet is not running. Cold water runs fine. Checked the Bathroom, and the tub and sink in there have the hot water running fine. Now, the Kitchen sink faucet has been giving me problems all last year. Turn the hot water on, and it would run , then stop for a few seconds and then run some more. Definitely NOT! frozen in the Summer when it is 90 Degrees outside !

Currently , it is -8 Degrees outside, with a Windchill of -25 to -30 Degrees.

Kitchen is 72 Degrees.

Is this just a faulty faucet or is it frozen ? The same hot water line that feeds the Kitchen Faucet , also runs to the Dishwasher. No hot water coming into the Dishwasher , either.

[Clarence Martin]

Well, this nice! Weather forecast says it is going down to MINUS 24 Degrees tonight!

If the dishwasher isn't getting hot water either, then I'd suspect frozen. But...see if the line for the dishwasher splits off after the shut off valve under the sink. I've seen those little valves go flaky and block water flow before.

If it is frozen, leaving the undersink doors open can help keep the area warmer, and of course allowing the faucet to drip a little usually prevents freezing.

Take the wife's hair dryer and stick it in the sink cabinet for a while see if it thaws out,

I was going to suggest the same thing.
I hate dealing with frozen pipes.

Centigrade.

[Clarence Martin]

Don't know if the hair dryer would be a good idea. Old copper pipe hooked up to PVC. Neither pipes feel cold. I think the the hot water knob has crapped out.

[Al Launier]

If the hot water hasn't been used to the kitchen sink in a while it would feel warm as you noted. Can you shut off both hot water & cold water feeds & then hook the hot water to the cold water faucet to see if you get hot water? If you do, then you should replace the hot water faucet, probably both.

Are you on a crawl space? Do the lines come from below (basement) or are they in an exterior wall?

I had a similar problem this summer. Turned out I had some debris lodged in the shutoff valve. Removing the valve would have been a bad chore, but I was able to attach a hose and flush it out. Isn't plumbing fun?

[Brian Henderson]

You need to figure out where the problem actually is. Turn off the water at the sink, remove the hot water valve, then turn the water on just a little to see if you have anything coming out. If you do, then replace the valve assembly. If not, keep backtracking. You say that the same line supplies the dishwasher and that has the same problem, maybe you have a problem with the line. Go back to the shutoff at the wall and unscrew the supply line, get a bucket and turn on the water and see if it comes out. You might have an obstruction in the line that you can either flush out or needs to be replaced. Once you get to the wall, it's a bit harder to check on your own without punching holes in the walls.

Well, now the cold water doesn't work in that sink. 72 degrees in the Kitchen . water works every other place. I turned the valve off that leads to the Dishwasher from the sink and turned off the cold water valve under the sink . The hot water valve is in the basement. Left that one on. Then I turned both valves back on. Knobs on the kitchen sink are wide open. No water coming out.

It's 72 Degrees under the Kitchen sink . Same as in the Kitchen.

Yeah, you've got an obstruction somewhere. You're going to have to backtrack the lines and repeat the process until you can find out where the problem is.

If both are not working the stoppage would have to be in the faucet at the diverter

Which is why I said to pull the valve, back when it was only the hot water not working. That's where the problem most likely is. He said that he's not getting any cold water at the shut off under the sink, or at least that's what I told him to check, which tells me that it isn't the faucet itself. And, of course, the faucet isn't going to affect getting water to the dishwasher.

For Clarence, to clarify, after you turned off the cold water at the shutoff, did you remove the hose from the cold water shutoff and see if you have water coming out of the pipe? We need to find out if the problem is at the faucet or further down the line.
