Hot water everywhere but kitchen tap. Unvented.

[armyash]

Been asked to look at a job this evening.

Resident has hot water everywhere but not at the kitchen tap.

Unvented cylinder. Someone has been and said possibly needs new pressure reducing valve but not confident.

I'm thinking possibly a dodgy mixer. Will see if I can isolate cold to the tap and see what happens. What else would you be thinking before you go based on this info.
Thanks

Patently it cannot be the cylinder as all would be affected.
What type of tap Ash? Have you checked the flow straightener at the spout end? Is it aerated and the aerator blocked?

Will be something daft faulty tap probably

Thanks, yes I agree sounds like a tap issue. It's a mixer from what I have been told. I'll be there to have a look soon and will update. Taking a mixer with me on the off chance.

Not pressure reducing valve.
Resident was told it was the immersion.

Was it just the hot gland come apart?

Just starting to seize. Not opening fully. Drain off under the sink, i opened it and ran it in to a tub hot water was fine. New reviver and sorted.

Nice easy one for a change.

Great when you get an easy fix!
The lower O ring inside those works wears and water gets inside and prevents the works screwing together and raising the washer. That is why you will find it is nearly always the hot side that gives trouble due to the hot water causing O ring to wear.
