Hi,

Anyone know where the valve is located on the CH expansion vessel
on an ideal response boiler, I need to check the pressure and the
manual appears not to show its location,

many thanks

You presumably mean the valve for checking/topping up the air pressure? I
don't know where it is, but it will look very much like a a car tyre valve.
If you look (and/or feel) all round the vessel, it shouldn't be too hard to
find.
