Hi,
We have a vaillant turbomax coiler (VUW 242E I think). When we turn on the hot tap the pressure drops immediately from 1.5 to 1 bar. When the tap is turned off the pressure rises again, but not to the same level (the decrease is dependant on the amount of time the hot water has been on for. I assume water is leaking somewhere (there is a trickling noise inside the boiler when the hot water is on)
