Mend Vaillant Combi Boiler

pressure too high?

the pressure on my vaillant combi boiler keeps going too high. A service engineer lowered the pressure and refilled the system but water dripping from the flute and though I lower the pressure it keeps going up? Is it ok for a few days until I get someone else in?
