Thank you for your question. The Delta 25770LF-SP faucet handles can be rotated differently by changing the orientation of the stem unit assemblies for the handle. To do this, turn the water off at your water supply. Remove the handle by unscrewing the set screw with a 3/32" allen wrench. Unscrew the bonnet nut counterclockwise. Take the stem unit assembly out and rotate so the small crescent-shaped stopper is away from the spout. Reinstall all parts.
