I have low hot water pressure on the kitchen tap down stairs.

All other taps are OK and appear to have sufficient pressure.

The kitchen tap seems to derive from the bath mixer which is situated above it in the bathroom.

Some time ago I heard a strange 'glugging' noise and the pressure then reduced. It appears to have got worse today and the hot tap is almost a trickle.

We have hot downstairs at the front of the house which is fine.

My house is 12 years old and the initial reduction was about 18mths after moving in from new.

The tap in the kitchen has been replaced as has some of the piping but the problem remained, so I don't think the problem lies under the sink .
My questions are:
1. Could the mixer tap be blocking the supply to downstairs?
2. Or could there be something such as solder jammed on a pipe bend between up stairs and down?
3. If the latter is some magical way to clear it? High pressure for example?

Thanks for your time and I would be grateful for any information on this.

Thanks

1. Could the mixer tap be blocking the supply to downstairs?
No, While the two may be fwd by the same hot main they are separate valves.
2. Or could there be something such as solder jammed on a pipe bend between up stairs and down?
Or a small pebble. To check to see if it's the valve or the supply, shut the water off under the cabinet and unscrew the raiser from the hot water angle stop. Now hold a pan over the angle stop to catch the water and turn on the hot water angle stop. You should have a strong stream. If not shut all the water off at the house shut off and remove the angle stop and check and clean the seat. Hold a pan over the open pipe while4 someone turns the water on for a minute. Full stream now? If no then click on back.
Before we go to #3 do #2 Good luck, Tom

Hi Tom Thanks for the answer, I will attack this at the weekend.

My feeling is though, based upon previous thoughts when I replaced the kitchen and changed the taps that the pressure coming down from upstairs is low, (it was low before I changed the tap and had hoped it would solve it, but it didn't) however I will take your advice and double check it.

Thanks

OK,
I have discovered a bleed valve at the point the hot tap connects to the supply under the sink.

When undone, the water runs powerfully.

So the blockage is not where I suspected it was. It is either at the point the taps fit to the piping or the taps themselves, could it be that the pebble has moved to the tap?

OK I can disassemble this part but need to cut off the hot supply. I must have done it before but I cannot remember how.

Can you advise me tom?

Thanks
