 No Hot Water in Kitchen.
Author: cruiced (FL)

I have no hot water in the kitchen, but it is fine everywhere else in the house (two bathrooms and the laundry room). I have replaced the hot water cut-off valve under the sink, and with the hot water pipe connections removed and the valve fully open, I only get lukewarm water dribbling out. Any suggestions? Could it be an air pocket in this one line? If so, how would I go about flushing this one line?

Thanks in advance for you input.

Keep tracking the hot water backwards with the hot water running at the spout. Feel the pipes back to the junction or zone valve.
Best Wishes

Thanks for the quick reply. Unfortunately, the pipe goes straight into the wall and disappears from there. Even with the cut-off valve completely reomved (just leaving the bare, open-ended pipe showing) the water only dribbles out.

Does anyone have an idea about what might be causing the blockage and/or how to clear it?

It is not an air pocket, but we cannot tell you what the problem is without being at your house and making an inspection of the system.

Are the water pipes, in the wall, galvanized steel pipes (or copper, or plastic)?

Copper.

What valve(s) did you turn off to replace the supply valve to the faucet? Did you make sure to turn that/those valve(s) back on?

If it was a gate valve it may have broken in the cold position.

Many thanks for the feedback so far - I greatly appreciate it.

I turned the off the valve for the whole house (outside). Besides the valve at the end of the hot water pipe (under the sink) there is no other valve on this branch - it feeds directly from the hot water heater. The hot water in the laundry room (which is closest to the hot water heater) is fine, as is the hot water in the two bathrooms (which are the furthest away). The sink is not that much further distance-wise than the laundry room sink.

Thanks.

Its hard to say what is happening from here. You might want to have a plumber on site check this out. It doesn't sound like and fast and easy cure.

do you by chance have a galvinized nipple coming out of a copper female adapter in the wall?.i know you said your pipes in the wall are copper,but i have seen people use the wrong nipples to stub out for the valves.they should be brass if there not.oh,the point i was getting at is galvy nipples do plug and sometimes a screwdriver or other pointed object can clear them(if not replace)...anyway good luck

Plubmerdan,

Thanks for the suggestion. I completely removed the valve from the end of the pipe (so there was just a bare, open-ended pipe sticking out of the wall) and the water was still only trickling out.

One final suggestion/idea that I'd like some advice on before I call in a plumber.

I purchased a garden hose/faucet adaptor yesterday with the idea of attaching my garden hose to the end of the faucet, opening the faucet to hot, and then, with the other end of the hose attached to an outside pipe, forcing water back up through the hot water pipe in question to try and clear out any blockage?
Before doing this, I would first drain three-quarters of the water out of the hot water tank, and isolate the tank from the outside cold-water supply via a valve on the top of the tank.
What do the professionals think of this idea?

it works sometimes, but open the safety valve on top of the tank, or a hot water faucet, preferably the bathtub, elsewhere so the water has a place to flow. You do not have to drain any water out of the water heater tank.

Worth a try, How about an air compresser. What do you have to lose at this point?
How about forcing a stiff wire back into the pipe if it is close to the blokage you might just might get lucky.

Moving water will move a blockage better than moving air.
