For some reason I always struggle to fit the Ultracom's filling loop at this end, whereas the Vaillant is a piece of pee![]()
I can't say it's been a problem for me tbh. You'd be amazed how many installers cock it up and connect to the r/h/s ch isolation valve (instead of the l/h/s) and leave the cold mains on the **** because it don't fit properly.
