Our Item #:


The eco-friendly thermostatic ShowerStart showerhead adapter TSV3 is the third generation of the Evolve ShowerStart TSV line, and features enhanced longevity to continually save hot water. It is designed to automatically reduce the shower head’s flow to a trickle once water measuring 95° F (35° C) reaches the fixture to save the hot water that’s used during the user’s warm-up routine (behavioral waste). The ShowerStart showerhead thermostatic adapter attaches directly to the shower heads and shower arms with ½" NPT fittings. The trickle continues until the normal flow is reactivavted by pulling on the TSV’s lanyard or toggling the bypass lever attached to the lanyard. Once the Evolve ShowerStart TSV3 has been bypassed, the shower head will continue to flow at its normal rate. The thermostatic ShowerStart showerhead adapter automatically resets itself for next use. It is designed to operate in plumbing environments with static water pressures of 30 psi or higher.
