Can I change my single handle knob faucet to a lever?

Single-handle lavatory and tub/shower models can be converted from a clear or smoked knob handle to a lever handle. However, the "action" of a lever handle differs from a knob handle, so you will also need a different ball valve (RP20111) in your faucet for the lever handle to operate properly.
A single-handle faucet converted from knob handle to lever handle will operate slightly differently from an "original equipped" lever model.
