The hot water tap in my kitchen has suddenly lost pressure.

as soon as I turn it on, we get pressure (not as much as orgininally) and then as it get hot the pressure reduces again to a trickle.

Anybody got any ideas as to how to fix it?

It needs stripping down, examining and either rebuilding with a new washer and some fresh grease or if it's a ceramic cartridge that needs replacing or it needs a new tap.

as above sounds lioke the washer has expanded and as it gets warm it blocks the pipe up

Thanks folks, the glad was stuck solid, ripped the tap off, replaced the gland eventually (the splined end parted with the gland and stayed inthe tap (uurrgghh).. some bashing later, fixed, gland replaced and bobs your uncle hot water under pressure out of the tap.

cheers
