F&E Tank Overflowing

I have just fitted a new bath with a mixer tap and now noticed when filling the bath the f&e tank overflows. The cold is mains fed with hot water from the cylinder.

My boiler is a Thorn M30/42b and a Coppermatic Cylinder c/w f&e tank above.

Any ideas what I can do to solve this??

Thanks in advance

cheers, will give it a go. :)

Having another look at the problem i see original hot pipework to bathroom in 22mm and reduced to 15mm under the bath. Should I reinstate to 22mm ?
It would increase the volume at the tap if you did, but not solve the problem. You would still need the check valve
