## Description

Hot Water Standby and High-Pressure Sprays! Tired of waiting for the hot water to be ready? Now it waits for you and adds convenience and freedom to your get-ready routine. Brush your teeth, use your toilet, make your bed, or pick an outfit without wasting hot water while you're away. When you’re ready to step in and begin showering, simply pull the cord to resume the high-pressure spray and enjoy. Enjoy getting luxuriously clean while getting lower utility bills. Our ShowerStart technology helps you save energy by cleverly and conveniently saving the hot water when it arrives. The Thermostatic Shut-off Valve (or TSV) triggers and stops hot water from running on and on by auto-pausing the flow when the temperature is just right. Enjoy more, use less. Save water and energy used before showering begins. You never have to keep checking on the temperature while waiting. Simply step in when ready and pull on the foot-long lanyard to start your regular flow. Our energy-saving valve works with standard fixtures so you don't have to buy any special adaptors or fittings. Its .5-inch NPT fittings make for easy connection to any standard head fixture or extension. The Evolve Thermostatic Shut-off Valve meets or exceeds standards set by WaterSense and the Uniform Plumbing Code. They are durable, stylish energy savers that don't compromise on your showering experience.

Review: Works great - Product worked great after some trial and error with the teflon tape.
Review: Amazing device! - This device has been a Godsend! I was so frustrated with the amount of water my teenage son wasted; he would turn on the shower then get distracted on his phone while the shower ran for 10-15 minutes before he finally got in the shower. I decided to give this a try, and it's amazing! He still gets distracted, but now the water flow drops to just drips, saving a ton of water. When he's ready to shower, he just pulls the cord to release the flow. Now I don't have to yell at him to hurry up. I'm so thankful for it!

### ⭐ Great concept but failed at 18 months
*by A***R on October 1, 2025*

This is a great concept and worked well for about 18 months. Then something failed internally and sprays a stream of water back towards the wall. I cleaned off the Teflon tape and replaced with new tape. No change.
