Screaming taps

[DaveT]

My kitchen water taps, Mainly the hot, make an awful scream/screech when switched on, really ear piercing.

Did have a problem with cent-heating a few weeks back. I have changed washers about the same time as problem started.
Also, about the same time, the hot water in general has gone really slow, takes ages to bath to fill, where as it used to be pretty good.
The original prob with cent/heating was low pressure after I tried draining the system. I didn`t know any different as what to do with new cent/heating compared to our old way of bleeding rads etc
Appreciate any help (The Mrs is starting to nag about it now)
Thanks.

OK, so you've some taps and a central heating system. So far so good, tell us more about the heating system.
