Plumber's Putty around sink flange

DIYGST

I installed a garbage disposal, stainless flange on stainless sink, I was wondering do you scrape the putty completely clean around the flange? Do you just use your finger nails or is there a better method?

It's kind of weird the putty is still under pressure from the flange, and a little comes out after I wipe it clean, just very little. I guess this will eventually equalize?

Tighten the lower nut, scrape the putty completely with your finger nail and your done. But a disposal also has screws that tighten up to the bottom to keep it from rocking.

i am having a similar problem, and when i use the disposal i get more of the putty coming out around the flange. the three screws on the bottom of mine are very tight (possibly too tight?) i had this problem before, and it eventually started leaking around the flange

The bolts should be snugged only. Yours sounds like it is too tight causing all the putty to squeeze out

Mine still has a little coming out around the the flange after a week, seemed to be settling down though.
I think the putty is under pressure, eventually when enough of it comes out it should stop?
Also when I run hot water to heat up the flange area, seems to soften the putty and squeeze more out. (maybe you can try this and report back, my faucet isn't hooked up right now)

Flange is tight and I think the putty is still moving around to fill the voids.

Bob, should we loosen the screws, would that cause a leak now?

Ayuh,.... I took mine out,+ Threw it away,.... Put a drain back in...

not likely. Just add putty again if you need to. These bolts help the unit stay stable while the starting torque tries to make it spin.
