Hi there,
I just replaced the pop-up drain in an old bathroom sink, and I'm getting a very slow leak that appears to be coming from the threads on the drainbody immediately under the nut that secures it in place. The rubber gasket and the plastic washer are in place above the nut. I used plumber's putty under the flange (where it sits in the sink) but the instructions said not to use tape or pipe compound on that nut, so I didn't.

Any thoughts?

Mahalo in advance for your help!

Aloha from Florida Jane,

I'm assuming the rubber washer's the one next to the drain and the anti-friction plastic is next to the nut. Sometimes it just takes another quarter turn on the nut to stop those pesky leaks. Give it a try and if you still have a leak click on back. Mahalo for using AMHD. Cheers, Tom

Thanks for the quick reply! Unfortunately, it's still leaking.
(And yes, the rubber gasket is next to the drain and the anti-friction plastic is next to the lock nut.) Sigh.

When that happenens to me I roll a real thin rope of plumbers putty, loosen the nut and insert the putty up between the rubber washer and drain. Tighten it down , the putty will squeeze out and what remains will act as a sealant. Good luck, Tom

You're most welcome. Tom

I had this same problem. Went so far as to replace the entire assy. With another new unit. The bottom surface of the drain hole was probably not flat enough to seal with the rubber washer. I tried your putty trick and lo and behold it worked! Thanks

I had this problem too. Your solution worked like a champ -- thank you very very very very much!! :D

Not my solution folks. That's just the way we install drains but thanks for the compliments and just glad it worked for yawall. Tom

The directions from Delta sure didn't say anything about doing this. I fought with the very slow leak until about 2 am, when I found your message.
