    Keep your routine. Save your hot water. The Evolve Multifunction Showerhead includes a ShowerStart TSV (thermostatic shut-off valve), allowing you to effortlessly save hot water between when your shower is warm and when you are ready to get in. Keep your pre-shower routine without the worry of a running shower. When the water reaches 95°F, ShowerStart automatically lowers the flow to a trickle, saving hot water until you’re ready to get in. Pull the cord to resume full flow and begin showering.

    ShowerStart TSV is compatible with homes having static water pressures of 30 psi or greater. This water pressure is necessary to ensure the TSV can be taken out of trickle mode by pulling the unit’s lanyard once the user is ready to begin showering. As a result, ShowerStart may not be compatible with homes serviced by wells.
