VAILLANT VUW 242 LEAKING

magictorch · 6 Oct 2006

My boiler is leaking from a housing with a switch to the upper left of the pump (I'm not sure what part it is). The dripping is continous (faster when the boiler is operating). Looking at the instruction manual I think its the differential pressure valve/switch. If that is what it is mine has been installed on its side if I follow the picture in the manual. The diverter valve was replaced last year.
The boiler is working OK although I do have to top up the system more regularly than I had to before the Diverter valve was replaced.
Any help/suggestions out there.

Anythiing can leak. Remake the joint or replace the part! Try new O rins if one of the small pipes is leaking at a joint.
