I'm putting in a new faucet.

The pop up stopper moves very little up (about 1/4" max). the manufacturer (toto) suggested I get a plumber!

I saw on another forum someone posted a reply to a similar issue saying it's all geometry.

I think part of my issue is that the drain body can't be too low on the flange? But it IS up close to the flange nut. But it's a kohler sink. So their sink 'thickness' is more than a toto? changing the geometry? If I unscrew the top of the stopper, I can then lower the stopper more (some of the height travel is lost because the top of the stopper closes the drain keeping it from traveling (down) farther. Not that it needs to go down more. but how do I 'raise' the travel of the stopper?

Only way I see that happening is by raising the drain body. But it's already as close to the flange nut as it could be. How tight can I go with the flange nut against the sink (it's a Kohler Caxton S2209 made of vitreous china).

any addvice?

thanks!

 

A 1/4" is all the travel you need to drain a bathroom sink.
Think you need more, the metal clip can be squeezed and slid out further on the rod.
