Leaking sink waste connection ?

    I have just fitted a new sink in my cloakroom which has one of these
    click/clack waste fittings, with the overflow running into the slotted waste
    fitting The plug fitting drops through the hole in the sink, with a plastic
    washer between the plug and sink, with another plastic washer/seal that fits
    under the sink with a large nut to tighten the plug to sink joint. My
    problem is I cannot tighten the nut enough to prevent water running down the
    thread of the waste fitting below the sink. I'm guessing that the water is
    finding a route either between the plug and sink on the top side, or
    possibly through the lower washer ? Is there a better way of sealing this ?

    Thanks

    Buy a tube of Fernox LS-X, apply thinly to all mating surfaces, leave for an
    hour.

    click/clack ..I presume you mean a popup waste .
    I have one of those and had no problem with any leakage but I think I
    dumped the upper washer and used Plumbers Mait to seat it .. As for
    the large nut underneath I have just had a quick look using a mirror
    and there is a washer underneath but I have a feeling it is rubber not
    plastic .I think I might have smeared it with LSX sealant and
    certainly I have had absolutely no problem with it since it was
    fitted. Are both the washers you got with the waste plastic ?...is one
    not rubber .

    Concentrate on sealing behind the nut.

    The lower one is rubber.
    So the general consensus seems to be to use fernox lsx sealant/plumbers mait
    and possibly not use the upper plastic washer either ?

    what goes on on the upper side makes no difference re leaks. Plastic
    washers just spread the load.

    The washer between the sink and the plug stops the water draining when
    the plug is down - leave it out and the sink won't hold water,
    although it won't cause a leak.

    I prefer using these http://www.toolstation.com/shop/Plumbing/Washers Fixings/Basin Mate 1 14/d20/sd2703/p37534
    on the underside rather than using sealant.
