Still got cold water pressure, heating is working fine, but the hot water pressure has dropped so low it makes showering near impossible!!

Any ideas!?

it would help if you could describe your system a bit.

boiler?
combi boiler?
hot water tank?
vented/unvented?

Sorry, it’s a combi boiler, does the heating and hot water from the same thing. The heating is on fine and the light for the hot water is on too just the pressure has gone really really low. If the shower is on and I put the tap on the shower stops!

is it the same drop in pressure across all your taps, mixers, individual pillar taps, shower mixer etc?

Bled your radiators recently?

Yep drop is across all of them. Nope not bled any radiators at all.

It was fine when I showered at 6.30 this morning but when mrs Crispo showered an hour later it was right down.
