Step by step
Place point sensors near water heaters, washing machines, and under sinks.
For a whole-home automatic shutoff valve, it installs inline on the main water line.
If comfortable with plumbing and low-voltage wiring, this can be a DIY project; otherwise hire a plumber.
Connect the system to Wi-Fi and pair sensors with the shutoff valve/app.
Test by simulating a leak (a wet paper towel on a sensor) to confirm alerts and auto-shutoff work.
Questions to ask your pro
- Are you a licensed plumber with experience installing smart water shutoff devices?
- Where on the water main will the valve be installed, and will it shut off the whole house?
- Will you test the automatic shutoff by simulating a leak trigger after installation?
- What is the power source—hardwired, battery, or both—and what is battery life?
- Does the system work if my Wi-Fi goes down, and how will I be notified of a shutoff?
- Is installation compatible with my pipe material—copper, PEX, galvanized, or CPVC?
- What is the warranty on the device, and does your installation labor come with a guarantee?
