    Baxi Combi 105e leaking!!! 20th Jul 06 at 7:42 AM
    Hi,

    Got the above combi boiler (Baxi 105e).

    Unfortunately it's developed a leak from somewhere!
    I've traced back to where the water is coming out; it's the Diverter valve Assembly; more specifically the water seems to be coming from the DHW Pressure differential valve - the part with the pushrod that controls hot water output.
    Looking at the blow-apart in the manual the likely suspect is the diaphragm.

    How easy is it to change this and where would I get this part from? (I cannot find the 105e on the Baxi website).
    I can isolate the water easily enough, but do I have to drain anything - should I attempt this job myself or get a plumber?

    Thanks
