Baxi combi 105 HE

Hi,
I am finding a small pool of water in the mornings, and I have traced it back the the 3 way diverter assembly, it is dripping from where the diaphragm housing couples the the 3 way valve assembly, is this simply a O ring, also do I need to drain the system to remove only the diaphragm housing part.
Regards
Scott

usually its simple o ring at the back of front housing buy a diaphragm service kit and the o ring that comes with it will do job . no need to drain just turn cold off and open hot tap

Be sure to use silicon grease.

Thanks guys, all sorted, I had drain the system after all, as I found the leak was coming from the diverter side, and a plumbing and heating shop in Sheffield opened his shop especially for the spares I needed, Tolsons was the shop name on Infirmary Road Sheffield, the guy really went out of his way
