Cheers. I tightened that until it can't go any further and it still leaks so wondering if the o ring is missing. Will have to look at rates to take apart. Looking at it again after I posted I think I can use remove the whole pump assembly rather than having to cut a hole in the walk so the elbow can do a full turn.

I'm just coming to the end of a self build and went to turn the ufh on with the recent cold spell and there's a leak in the manifold where the elbow joins. Does anyone know how these elbows seal? I currently can't fully remove it to see (as wall behind blocks the turn) so wanted to confirm I need to take it off before I start cutting holes in the wall behind. Thanks
