and it is freaking leaking, driving me crazy. I tried caulk and it leaked. Then I tried putty and it is still leaking and I can't figure out why and where. If I am leaving water in the sink for a while I am seeing/feeling humidity in the area marked with the red arrows.
As far as I understand the construction of this thing the water could leak via two ways (red path or the blue path in the above picture) How do I determine which way the water is leaking? Is it possible to fix this by using Teflon tape or thread dope ? Should I even try that since the water is leaking from somewhere above in the first place ? Assuming everything is solid with the pop up and with the putty I am assuming the water could sit there in the overflow cuts from the last use of the drain and then it leaks down through the white and red gaskets. I suspect that this is what is giving me grief since the water in the sink does not seem to go anywhere ...this is not a masive leaking it would take maybe more than an hour or two to see a drop in the pan that is sitting under the drain right now. The reviews on the home depot side are not that great and the 1 star reviews complain about the same issue-leaking
