Hi
Previous owners had a Vaillant Turbomax installed last 3 yrs back and we have moved in a month back. The boiler everytime when en a central heating is on and we switch hot water, it makes a loud bang in the boiler; also pressure drops every week. I have checked for the leaks etc... but seems to be fine. Can someone please help.
Many Thakns
