I recently had a new granite vanity installed w/ 2 undermount sinks and new faucets/drains. The the fellow doing the plumbing said there was not enough clearance below b/c of the deeper and undermount sinks to operate the drain by the vertical lever up top that connects w/ the horizontal lever below that attaches to the drain. Do they make an off-set lever system so I can operate my sink drains by the vertical lever adjacent to the faucet?
