New install Worcester 30i, green leakage from flow & return... any ideas??

It`s not clever to misquote either darling!

Be careful with the darling rpm unless your sure that OP is Female ! :gorgeous:

My guess is it could just be a bit of flux on the pipework. That goes green if not fully cleaned. I wouldn't worry.

It's got the keyless system for refilling, if that's what you mean? Blue handle underneath, much easier than the old boiler taps for flow and cold inlet. Leak isn't from that bit though, as that's the cold inlet which is to the left of the CH return.

It should be connected to the return though, that's how it fills the heating system
Any better pictures

Had the same with a compact today I went to. Looks like flux a weird type of lime scale.
