You'll need to buy a vessel sink drain without the holes. Don't try to plug the holes in the one you have. https://www.homedepot.com/p/Bathroo...rflow-in-Oil-Rubbed-Bronze-TA-PDORB/307833592
Yeah, I don't think those vessel drains will work for me.Sorry but Chandler48s' solution will not work. The vessel sink drain is designed to fit a vessel sink. Notice the seal that fits the flat of the under side of the vessel sink surface around the drain.
Check that you installed the black rubber gasket properly, bevel side up. Put a small bead of plumbers putty under the lip of the drain flange. That keeps water from leaking out of the sink when sink has water in it and the stopper is closed. Never heard of someone using plumbers putty on the black gasket.
So remove the drain and inspect, put back in place with black gasket bevel side up, Install drain flange with putty under the lip. Push black gasket up and tighten nut. That black rubber gasket is flexible enough to seal even if there is small imperfections in the drain opening.
You need to purchase a different drain assembly... You have been shown options that will work. You can also Google pop up drain without overflow. The selection is endless.
Putting a patch over a hole is not the proper approach and I doubt it will last long....Here's one that should fit your budget https://www.menards.com/main/plumbi...erflow/501pw9875bn/p-1444437577694-c-9417.htm
Right you are---:wink2: They are available and not overly expensive..Nope. Has the overflow hole.
Yes, the holes are above the gasket. It seems water runs down the threads and past the rubber gasket. It very well might be an issue with the sink. Maybe it's not perfectly round and the gasket isn't able to seal correctly. I found a video that shows a drain, sink and issue very similar to mine.You will probably have a hard time finding a drain assembly without an overflow. Remove your drain by holding the drain flange and unscrewing the drain assembly. Take note of the location of the drain gasket and the overflow holes. Gasket should be well below the overflow holes. If not, cut off enough of the top of the drain to make the holes in the side of the drain about 1/2" above the gasket below when tightened.
Look at the drawing, if the gasket is below the overflow drain holes the water will be blocked regardless of its source.
As implied in the drawing I suspect that the flaw is in the sink, not in the drain assembly as was my case. It just wasn't worth my time to return it, I have and have had a bathroom sink without an overflow for 30 years. I suspect the same in your case. I seldom close the drain. The purpose of the overflow hole is to prevent overflow if you forget to turn off the water.
The drain is plastic, easily cut and the threads are not precision ground threads. So either cut off the top of the drain or return the sink.
PS
Look in the interior walls of the sink drain opening and see if the drain lines were cast in the sink. Suspect they were. Suspect they are required. Just a screw up.
I was just reading all the malarkey here regarding drains for sinks without overflows; geez, this isn't rocket science. As chandler48 said and even gave you all a picture link for, that is the exact drain I have been using on all of my sinks without overflows and Moen Brantford faucets. It works perfect, no issues whatsoever.You'll need to buy a vessel sink drain without the holes. Don't try to plug the holes in the one you have.
