    Hi All
    I'm thinking of getting a new WB 30i System boiler with the optional diverter kit as opposed to zone valves. The diverter kit only has 15mm connections to it whereas most people seem to suggest running 22mm pipe to the HW cylinder. I phoned up WB and they just said to run 15mm but guy on phone was basically looking at info in manuals.
    Any suggestions?

    Always follow Manufacturers instructions, they have done their reseach If that what they say then thats how it should be done
