    I am in the throws of replacing one.
    My plumbing friend said use, silicone, not plumbers mait.
    In the past I have always used plumbers mait, you can test for leaks immediately, using silicone do I have to wait for it to set before I check for leaks.

    If the silicone is just coating a washer or joining two flat faces, you should be fine to use it straight away. If however the silicone is filling a gap, you will need to let it set first.

    One of the problems of using "slippy" goos like silicone on rubber washers is that, as you pull up the connection, the washer can actually "expand" and extrude out of the fitting due to the "slippy" sealant used.

    If using a silicone type sealant I find Fernox LS-X excellent since it actually sets under water. Hence on something like a basin outlet, the system can be used within say 1 hour.
