FAQ

The usual
questions.

Can Castle shut off water remotely?

Yes. The Castle meter has an integrated shutoff valve, and authorized users can control it remotely from the platform.

What happens when unusual water activity is identified?

Castle flags it as an anomaly (continuous flow, sudden increase, low-temperature/freeze risk, or missing meter data) and sends an alert identifying the property, urgency level, and recommended next step. Users can review and act (including shutting off water) from the same screen.

Can Castle help explain why a utility bill increased?

Yes. Castle reconciles usage against utility bills, so property managers can see whether an increase came from actual usage, a leak, a rate change, or a billing issue.

Can Castle handle resident water billing and payments?

Yes. Resident billing and payment/collections tracking are part of the platform.

Can Castle show how much of the eligible utility expense was billed and collected?

Yes. Through utility-bill reconciliation and payments/collections tracking, Castle shows how much of the eligible utility expense has been billed to residents and how much has actually been collected.

Does Castle require property Wi-Fi?

No. Castle uses NB-IoT cellular connectivity, so it doesn’t depend on the property’s Wi-Fi network.

Where is the Castle meter installed?

It’s installed inline on the property’s water line, as permanent infrastructure, not a clamp-on or retrofit sensor.

Who handles installation?

Professional installation. Because Castle is installed inline as permanent infrastructure, it requires a plumber or certified installer rather than a self-install.
