my vaillant boilers pressure is dropping almost everyday. I've to fill with the water. if the pressure is on bar 1 after arating the boiler it goes to bar2 and after switching off I find pressure has gone down bar1. that's how its pressure is dropping. I can trace water gone out through pressure release pipe.
