Just curious on others opinions. When you install one of those click pop up waste plugs you can get a good seal at the sink (top end) however when you run water it bypasses the sink seal and can flow in to the slots for the overflow, meaning you then have to have a good seal under the sink as the water can run down the connection threads. Thats what happened to mine altough light use of plumbers mait resolved it.
Anyone else had issues with these?
