Slow-running hot water from kitchen tap only (combination boiler)

[Morphysm]

Hi all,

The tap in my kitchen is a 'mixer tap' and the hot water runs very slowly.

A few details:
- the tap itself still seems to get very hot despite the slow flow
- none of the other taps (hot or cold) in the flat run slowly
- water is heated by a combination boiler

Does anyone know what the problem is likely to be? I have no background in plumbing and have been unable to find a clear answer through Google searches.

Any help would be much appreciated.

Cheers,

Morph

Could be any of a large number of things. Things to try:

a. Clean / de-scale the nozzle of the tap. The hot water usually comes through the centre.
b. Change the washer / cartridge. Isolate the hot water first.
c. Is there an isolation valve under the sink which is not fully open?
d. Is the tap connected to the pipework with flexible connectors? If so, are either / both kinked?

If the tap worked originally, then something has gone wrong / deteriorated. If its never worked properly there could be a pipe work issue.

Beyond the above I think you'd be better off getting someone in to look at it.

Thanks for such a helpful and quick response, steadyon - I will give those suggestions a go.

(Answers to c. and d. are both 'no' btw)
