Automatic Toilet Shut-Off Valve for Leak Prevention

An automatic toilet shut-off valve controls water supplied to a toilet without requiring someone to manually turn the toilet’s angle stop on and off. The Toilet Scrooge™ uses bathroom occupancy to determine when the toilet should receive water.

A motion sensor detects when someone enters the bathroom and opens the valve so the toilet can receive water normally. After the bathroom becomes vacant, the valve closes and helps limit continuous water supply to a running toilet.

No. A toilet overflow sensor detects rising water levels or potential overflow conditions and may trigger an alert. Toilet Scrooge™ works differently. It automatically shuts off the toilet's water supply when the bathroom is unoccupied, helping prevent continuous water waste from running toilets without requiring someone to respond to an alert.

The Toilet Scrooge™ is designed for tank-filled toilets and has 3/8-inch fittings on both sides. Installation may use compatible hose-line or hard-line connections. Check the product specifications before installation to confirm compatibility with your toilet.

The device uses a miniature water wheel to harvest energy from water flow during flushing and recharge its power source. This helps reduce routine battery replacement and maintenance.

If the manual angle stop, supply line, fitting, or connection is leaking, that plumbing component should be inspected and repaired. The Toilet Scrooge™ helps control the water supplied to the toilet but is not a substitute for repairing damaged plumbing.

When choosing the best toilet shutoff valve for rental properties, landlords should consider five important factors:

1. Automatic shutoff: Choose a valve that automatically controls the toilet's water supply to help prevent continuous water waste.
2. Toilet compatibility: Make sure the valve fits your existing toilet supply lines and plumbing connections.
3. No-wiring installation: Look for a device that installs easily without electrical wiring or major plumbing changes.
4. Low maintenance: Consider a water-powered valve that operates without batteries, reducing ongoing maintenance.
5. Easy verification and proven results: Choose a valve whose operation can be checked in each unit and look for documented water savings from real properties.

Toilet Scrooge™ offers automatic, motion-activated water control with a water-powered design, making it a practical option for multifamily properties.

Potential savings depend on your property's current toilet water use, the number of units, existing leaks or running toilets, and local water and sewer rates. Use your building information in The Water Scrooge savings calculator to estimate the potential impact.

According to the U.S. EPA's WaterSense program, a running toilet can waste around 200 gallons of water per day, leading to higher water bills. See how The Water Scrooge™ helped a 46-unit building reduce water consumption by 53.7% in our 144 East 22nd Street case study.
