Review on 🚿 DANCO Shower Volume Control Shut-Off Valve - Chrome 1.6 inch, Pack of 1 (89171): Enhance Your Shower Experience by Jeff Jones

This is a great option that looks good and is durable. One issue was that before purchasing I had read several reviews stating that you need a rubber gasket for a leak free installation. This is WRONG and has actually resulted in me spending hours diagnosing a loose connection. can only make it harder to get a proper seal (as was the case in my case). Unless you know otherwise, you most likely have a tapered thread. After I removed the washer, the device was actually able to thread more onto the arm threads, which improved the seal. So the moral is that the block doesn't come with a rubber grommet because it doesn't need one. Don't trust the reviewers who used it, they won't install it properly unless they replace the NPT lever with a straight threaded tube.
