This Everbilt shower head flow control valve is designed to help reduce water volume at the showerhead, allowing you to effectively conserve water and save energy during your shower while maintaining the selected water temperature. Made from lightweight and durable plastic construction, it features a highly reflective and stylish polished chrome finish that easily coordinates with existing bathroom fixtures. Equipped with a standard 1/2-inch Female Iron Pipe (FIP) inlet and a 1/2-inch Male Iron Pipe (MIP) outlet connection, this straight-through shut-off valve is easily installed directly between your shower arm and the showerhead. Operating via a simple turn mechanism, the valve can slow the water down to a minor trickle or open up to full volume as needed, serving as an efficient water-saving retrofit accessory for standard residential plumbing setups
