Leak in kitchen sink--help!

WaywardWordNerd
by WaywardWordNerd
We have a leak somewhere under our kitchen sink and have been having a devil of a time finding it.
My husband replaced and resealed all of the pipes under the sink, replaced and repaired the gasket for the disposal, and replaced the gasket for the sink drain leading to the disposal, and we're still finding small puddles of water under there.
I know how faucet does leak some when you turn it on. You can see a small bead of water come from the handle. Could that be it?
Any ideas on where we should be looking now? It's driving me crazy!

    Did he replace the "plumbers putty" in the drain flanges (the metal part that is in the sink). Often wrestling these about will cause "new" leaks. New PVC drain parts are pretty cheap...I would strip everything back toss all the old plastic and start with new. Pull the drain flanges, clean all of the residue of the old putty from the sink hole and re-install with fresh putty. Re-using 10 bucks worth or smelly plastic is not worth the headaches in my book.

      @KMS Woodworks He did replace the plumbers putty, although we did find a very small leak coming from the disposal drain. The main puddle is coming from under the faucet, and he is thinking about replacing all the gaskets in the faucet.
  • you still need help with that ?

    Maybe? He hasn't really been able to work on it and the leak seems to be very small. Only a small puddle--easy to clean up. I want to wait for him to replace the gaskets on the faucet and find the leak in the disposal before trying to trouble shoot more. Thank you!

    Would colored water help find where the trouble is?
