Ok!! so how do I check the EV pressurisation?

He replaced the prv as I had the same problem and the overflow pipe was leaking alot. the leaking has stopped and he said that he doesnt think there is a leak, but I should pay him for a power flush which I havent. He also mentioned replacing the EV, but I am not sure if he is just talking...

The pressure on my Vaillant combi boiler (Turbomax VUW242E/282E) keeps going down to zero and need to find out why and what needs to be done to keep the boiler producing HW for both the heating and taps. Recently an engineer replaced the valve but that didnt fix the problem.
