Review on Delta Faucet RP24096 Stem Assembly by Melvin Balamani

I called Delta and they insisted that this stem assembly would fit my ancient Roman bath faucet. I didn't have a model number but they just wanted to know how old she was (about 12 years old) and if she had pins or buttons (buttons). This block is nylon with a brass shaft while the old one was all nylon. This was normal as the wave is not visible. You were right. It fits perfectly. I also replaced the seat and spring under the assembly (sold separately) and used some plumber's grease to lubricate the new parts. It's a half turn to fully turn on like the old device, and the instructions show you how to set it up so that the turn from off to on is in the same direction as the old device. Very smooth and easy to rotate after installation, no leakage.
