    Hi All
    I have a white 1 1/2 plastic sink that is leaking where is appears to have corroded at the bottom. Is there anything I can do to fill it?It leaking from the half sink outlet, so unsure why it would have degraded more as is not used as much

    Good news is that it is unlikely to be the sink itself, most likely the watertight seal underneath is the cause.

    Dear Betty,

    So it looks like its leaking between the sink and the "waste" (the white plastic bit). Can you take another photo looking down into the sink from above. Is there a screw there to tighten it up. If you get hold of the waste does it move about at all in relation to the sink? When tightening any screw from above dont overdo it. If you can, take off the waste (remove grey pipes lower down first, and the overflow connection etc. ) Take the waste off then and clean it all up. If there is no rubber sealing ring then it needs some sealant. Try a non setting one first e.g. plumbers mait putty.

    Ok Roy I will give it a go but as the sink is in another property I will follow your steps at the weekend
    See the photo please
    Will the plumbers mate putty seal it long term?

    Probably needs a new one. Remove the old and take it with you. Doubt you will get white now. Will probably be chrome.

    White wastes are available however is that an euro sized fitting (Silver pipe)?

    Don’t think so mate. Just a cheap fitting. But I have been wrong before.

    Threads part or the plastic part the threads are fixed to might have perished.
    If tightening the nut doesn’t tighten the waste, you will need to buy a new drainer waste (with overflow connection)

    So I had another look at sink on Saturday. There is no screw that can be tightened or loosed from the top of sink, it just looks like you can turn the bolt with something as there are two indentations on the bolt for this.

    I was unable to budge the white waste pipe from below.

    So I understand I will need to get a replacement waste fitting if this is possible??, please confirm

    On that type you use a socket or spanner to remove the bolt.
    Waste connection should just slacken at the grey nut and you need to also undo the white nut which is probably to the overflow.

    I don't think it's IKEA but you will need a new waste, try Howdens or a well stocked plumbers merchant.
