Loss of hot water pressure in a single tap

[Doors27]

Hi,

I'm new to this so apologies if i have posted to the wrong thread/forum.

I was using the hot water tap in the kitchen when quite suddenly the water pressure dropped to just a trickle. However no other taps have the same issue,including the utility room tap which uses the same pipe.

Can anyone offer some advice as to what the problem could be and how to fix it?

Thanks and best wishes

do you have a cylinder system??
thinking airlock

Possibly the washer has come off inside the tap.

Hi Hammers4spanner, we do have a hot water cylinder in the airing cupboard (i hope this is what you mean!). Is there an easy way to tell if it is an airlock and if it is, how would i solve this with my (very) limited plumbing experience?

Hi Stoker, thanks for the reply. Stupid question, but would this be on the tap itself or part of the mechanism under the sink? Can you tell i'm not very plumbing proficient?

You would need to isolate the water to the tap, remove the head/handle then the tap valve/cartridge can be unscrewed using a spanner.
Out if curiosity, is the head usually a quarter turn from off to full on?

Stoker, yes the head is usually a quarter turn from off to full on - why do you ask? Is this a common problem?

No but that means it has a ceramic disk cartridge which doesn't have washers.
Could be a piece of debris (scale or other foreign body) blocking the inlet or as H4S says, an airlock.
I would isolate the tap and remove the cartridge first.
