The original diverter was only 8 years old, it's irritating to have to spend the money to replace it when plumbing fixtures should last 20 to 30 years before failing like the original. Replacement was necessary because it would no longer divert water to the shower head. The replacement is already showing signs of finish failure, white spots under the top finish after less than a year. Delta used to be a quality company, no more.
