FAQ

Can ShowerStart save the cold water too?
The cold water within the plumbing lines (structural waste) will exit through the showerhead. ShowerStart will reduce the
showerhead’s flow to a trickle once near-bathing-temperature water (95F/35C) arrives. As a result, it prevents the inadvertent warm
and hot water waste associated with people’s warm-up routines. It is not a cold water savings device.
Will ShowerStart work in homes with low water pressures?
The standard version of the 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.
More recently a specialized version of the ShowerStart TSV that is capable of operating in static water pressures below 30 psi is
available. Please contact Evolve Technologies for additional information on this version of the product.
How does ShowerStart’s trickle impact line pressures?
Evolve Technologies has conducted testing to determine the impact of ShowerStart “trickle mode” on pressure within the plumbing
line running from the shower’s mixing valve to the showerhead. The following fixed parameters were used:
• incoming pressure set to 30, 35,45 and 80 psi – a different static pressure for each test
• 2.5 gpm, 2.0 gpm, and 1.5 gpm showerhead flow rates were tested – each rate at each psi
• hot water (130 F) exited tank style heater – no cold water mix
• readings taken at showerhead – simulates back-pressure between mixing valve & showerhead
• readings taken with showerhead in both normal flow and “trickle mode”
