General Instructions

1. Make sure you have quality replacement parts. Know what type of parts you need based on the product series and the reference sheet on the instruction manual or by visiting the official website of Delta.

3. Open a faucet in the bathroom to relieve pressure.

4. Cover the drain with a towel or rags to avoid dropping parts in the drain.
