are expansion vessels expensive,baxi genesis 80 combi, if over pressurised,how do you get the pressuree normal,and is this what causes water to drip outside from overflow pipe from the boiler
look for a drain valve on the piework or rads, put a hose on it and open.

how do you run water off please

YOU HAVE TO DRAIN SOME WATER OFF THE SYSTEM, IF THE VESSELL IS FAULTY YOU WILL KNOW BECAUSE WHEN THE HEATING IS ON THE SYSTEM PRESSURE WILL RISE AS IT HEATS UP.
