Saves Hot Water
The Water Scrooge™ ShowerStart® helps prevent hot water waste while the shower is warming up.
Once hot water arrives, the flow is automatically reduced to a trickle until the user is ready to shower.

In multifamily buildings, shower waste doesn’t only happen while tenants are showering. A lot of it happens before the shower even starts.
Tenants turn on the water and wait for it to get hot. While they brush their teeth, shave, check their phone, or walk away, hot water keeps running — and landlords keep paying for it.
You pay for water and heating energy even when nobody is actually using the shower.
And in a building with many units, this small daily habit becomes a large monthly expense.
ShowerStart® technology is designed to conserve hot water that would otherwise be wasted while tenants wait for the shower to warm up. Once hot water reaches the shower head, the valve automatically reduces the flow to a trickle until the user is ready to enter the shower.
Normal flow is restored when the user activates the valve.
That means tenants still get a comfortable shower — but the building avoids the waste caused by showers running unattended.
The ShowerStart® valve senses when hot water reaches approximately 95°F and automatically slows the water flow. The user then restores normal shower flow when ready.
This helps prevent “behavioral waste” — the water and heating energy lost during the warm-up routine.
Tenants can still turn on the shower and wait for hot water like they normally do. The difference is that the fixture helps control the waste automatically.
Available ShowerStart® showerhead models include pressure-compensating flow regulation, full-body spray options, rub-clean anti-clog nozzles, and efficient flow rates.
For bathrooms with tub spouts, the ShowerStart® Express Tub and Shower System adds another layer of savings. The tamper-resistant version is positioned specifically for multifamily properties and is designed to combine comfort, convenience, and conservation.
It can help in three ways:
Hot Shower Standby
Automatically slows empty-shower flow when hot water arrives.
Efficient Showering
WaterSense-certified showering options deliver high-pressure sprays while conserving water.
Tub Spout Diverter Leak Reduction
The system helps stop hot water from exiting the tub spout while the shower is running.
Another big savings is that the tub spout shower starts, preventing how water leaks when the hot water valve is broken, running continuously!
Warm-up waste costs money twice: once for the water and again for the energy used to heat it.
Tenants can step away during warm-up without letting hot water run continuously.
The message should not be “take worse showers.” The message is: enjoy the shower, waste less before it starts.

Simply connect it to the shower setup and start saving water and energy.
Tenants can still enjoy a comfortable shower experience.
ShowerStart® technology helps reduce waste before the shower begins, without asking users to take shorter or colder showers.
