Sink Baskets and putty or caulk

You tighten until, well, it is tight. Firmly in place. Doesn't wiggle.

You can't use too much putty, excess will squeeze out as you tighten. That's what it is supposed to do.

After things are tight, wipe off excess putty. A pointy piece of wood is handy for grooves.

And you definitely want to use plumbers putty, not caulk. I've seen sinks done by hack jobs using silicone caulk and it's a disaster. Great product, but totally wrong for the application. The PP has the riight consistency and properties to bed the drain in and prevent water from leaking out.

When you tighten it, a good amount of putty should come out from all around the drain. Corrrect tightness is using a pair of pliers, but not forcing it really hard. You want it good and snug, but don't overdo it.

Also, warm it in your hands, rolling it into a "rope," which makes it easier to place. Excess simply squeezes out.

The instructions for the last tail-piece I installed in a sink said to use silicone, *NOT* plumber's putty.

Stop just before it breaks. ;-)

Probably because it was made in china and they don't know any better.

It was probably made in China, but the instructions weren't.

I've always used silicone rubber and never had any problems with either looks or leaks.

The only concern I would have is replacement may be more difficult.

The one I just did in the bathroom said to use caulk which I did...No leaks...
