- On the Delta site, it says "Min. 2-1/2-Inch clearance to backsplash recommended." I see that yours are pretty close to it. Is there a limited range of motion with the levers? Are you able to clean behind the faucet? I myself have less than an inch clearance (I plan to put it on a vanity), and really would like to buy this faucet. Please let me know. Thanks!
