Thank you for your question. To replace the bonnet nut, first turn off the water supplies under the sink. Next, unscrew the lever from the handle, loosen the set screw with a 1/8" Allen wrench, remove the handle, and unscrew the bonnet. Tighten the new bonnet hand-tight plus a 1/4 turn with a wrench.
