Thank you for your question, and I am sorry to hear that you are experiencing an issue with your Delta roman tub faucet. If the faucet does not divert water from the spout to the hand shower, check that
the lift rod is securely threaded into the diverter . If the problem persists remove the lift rod and spout. Replace the diverter assembly RP40668.
