Hello,
Went to top up the pressure in my combi this morning (routine annual process), and when I removed the key I noticed the filling loop was dripping and was continuing to do so.
The cold main nut is fully tightened and the drip seems to be coming from the boilder side of the loop. Does anyone know if there is a check valve in there that might have failed? For now I've left the key in the locked position which has stopped the dripping but doesn't seem like a proper "fix".
The filling loop assembly is about £30 so not the end of the world but wanted to check it is likely that black plastic part as opposed to something more sinister.
Thanks in advance,
James
