Frequently Asked Questions
How does SimpleSub work?
SimpleSUB uses ultrasonic technology to measure water flow without cutting into the pipe.
Each submeter straps onto the outside of the pipe, runs on a built-in battery, and sends data through a cellular connection, so there is no WiFi, hub, or external power required.
Once installed, you can view usage, billing, and alerts in the SimpleSUB web app.
What's included in the monthly subscription?
SimpleSUB Water’s monthly service fee includes cellular connectivity, real-time monitoring, access to the SimpleSUB Dashboard, a 5-year warranty, and lifetime data retention.
Why cellular instead of Wi-Fi?
Our meters connect directly to the strongest cell tower in your area, ensuring secure and consistent data transmission without requiring Wi-Fi. Cellular connectivity simplifies large property installations by eliminating the need for a reliable on-site network, repeaters, gateways, and other hardware.
Is installation difficult?
Not at all. SimpleSub installs in minutes using just two zip ties — no plumbing experience required.
What pipe types are supported?
SimpleSub works on copper, PVC, CPVC, PEX and many other types of pipes. It is not compatible with galvanized steel.
