More Hot Water with Your Smart Shower

The evolve ShowerStart TSV3 is the eco-friendly solution to saving water and knowing the right time to hop into the shower. The evolve ShowerStart TVS3 uses an integrated temperature sensor to detect when the water reaches the best temperature for showering and slows down the water flow so hot water isn't wasted, saving you water, time, energy, and money. Simply attach the ShowerStart TSV3 to your showerhead and you'll start saving water and energy while eliminating the guesswork of when your shower is ready.

  • ShowerStart® TSV prevents hot water waste during shower warm up
  • Stops water flow when temperature reaches 95°F and resumes flow when cord is pulled
  • Attaches to shower arms with 1/2-inch NPT male fittings

The ShowerStart TSV3 installs between your showerhead and shower pipe. When you turn on your shower, the showerhead adapter allows the water to run until the temperature reaches 95°F. At that point, the adapter slows the flow down to a trickle until you pull on the cord to begin showering. This process saves you from spending excess money and energy on hot water that you aren't using and removes the guesswork out of wondering when your shower is ready.

Installation Details

The ShowerStart TSV3 can be easily installed onto your shower pipe. Stretch plumber's tape the screw threads on the shower pipe to create a solid seal. Tighten the ShowerStart TSV3 by turning it clockwise into position. Finally, apply plumber's tape over any exposed threads and tighten the shower head onto the TSV3.

NOTE: The ShowerStart TSV3 is not an anti-scald device: Lower water heater to a maximum of 120° F (49° C). Always resume water flow and check water temperature before entering shower. Tankless systems require a minimum flow rate to produce hot water. When this product is used with some tankless systems a brief, yet noticeable change in the shower's temperature may occur shortly after resuming the shower's normal flow.

Experience The Luxury Of Convenient Conservation

Utilizing the unique, patent-pending ShowerStart technology, evolve products allow you to continue multitasking – only now you're saving water instead of wasting it. Evolve showerheads and adapters do this by stopping the flow to a trickle when the water reaches a comfortable 95 degrees. This way your hot water is no longer running down the drain while you're away from the shower. Using an evolve showerhead or adapter can save a yearly average of 2,700 gallons of water, the fossil-fueled energy it takes to heat it – and up to $75 off your utility bill.
