I have an ariston euro combi (A/23 MFFI) the prob is I have a leak at the DHW outlet at the point where it enters the (what I think is the diverter valve). I would like to know how the pipe is fixed into this valve and would it be possible just to tighten the joint?. I am a Plumber but only do bathrooms and showers, so this is all new to me!! any suggestions would be great and how would i go about draining the boiler?
