    I recently moved into a new house and have leaks on the kitchen sink and two basins.

    1) The kitchen sink: Water leaks around the sink overflow connector when water is allowed to fill up to the same level as the overflow or the mrs empties a bowl of water a bit quick, resulting in a lot of splashing! The leak appears to be around the connection between the overflow connector itself and the sink as water dribbles down the outside of the sink under the worktop and drips into the cupboard.

    ssuming the plumbers have tightened the connector up properly, what can you suggest would be the best way forward to correct this problem? Sanitary sealant? Fernox LS-X? A new overflow and strainer kit?

    2) WC and main bathroom basins:

    Water is able to leak through the joint between the monobloc tap and the basin itself.

    The builders have sent round plumbers several times to fix this problem and always reports the leak is fixed, yet when I get home I splash some water around the base of the taps and the water immediatelty leaks through. The monobloc should be connected to the basin using the fixing kit as shown in the installation diagram at the following link:

    I haven't done too much to check that it has been done correctly, other than to check they have used the correct fitting kit because I was refusing to sort it out myself out of principle,

    I have no idea why they can't seem to fix the problem but now (out of frustration) have decided to do it myself as It'll be quicker and will result in drier carpet and lino!

    What would you suggest? Assuming the fixing kit has been fitted properly and tight enough, would it be a good idea to removed the tap and use a sanitary sealant between the basin and the tap, as well as the supplied C-shaped washers?

    By the way, can anybody tell me what size the nut (item 6 on the installation instruction) is likely to be? I think I need to buy a tap wrench but don't want to get the wrong size.

    Thanks for your help!!

    i'd check the overflow isn't damaged or broke
    more likely fit a new plastic overflow.

    the basin tap should have an o ring fitted under the tap to seal between basin.
    n0 15 on your pic

    a set of these will do the backnut.

    in regards to the overflow leaking, you could loosen the connection, put a trip of clear sealant around the outlet and tighten the connection.
