I have no pressure on the guage on my Vaillant VCW sine 18 T3WFH.
I have been told I need to add pressure by the filling loop but I can't locate this.
Does anyone know whereabouts on the boiler it is please?
Many thanks
The filling loop looks like the image on the link

These do vary, but it's a good way to start your search. Generally speaking, it's usually fitted in proximity to the boiler itself. But you're talking a Sine 18 which are rather old, and configurations for filling points differed greatly in the 80's
