Hi all, thanks for you replies!
We’re going to call the installer to come and have a look on Monday.
He did a chemical flush when he installed.
We think our water pressure may be too high? He said he can install a pressure reducing value on our mains inlet? Not sure if the water pressure could...
We’ve had our Vaillant ecoFIT pure 825 combination boiler installed 2 weeks ago.
When we now turn the hot water on the boiler makes a very loud noise. Is this normal? (Video linked)
Also since changing over from our old Water Cylinder System/old Boiler, our taps & toilet have been much louder...
