Before the shortlist
The first four answers do most of the work
A useful ranking starts only after the constraints specific to this market are clear.
- 01
Must the system close water automatically, alert only or protect one appliance?
- 02
Which supply branches, fixtures, appliances, drains and non-potable sources can the sensing architecture observe or miss?
- 03
What valve type, pipe size, meter, pressure regulator, backflow device, bypass, freeze exposure and manual recovery path exist?
- 04
Who will install, permit, commission, maintain and respond when power, network, cloud service or a valve fails?
02

Market language
The terms a useful comparison should define
- Automatic shutoff
- A powered valve closes after a configured signal; it does not guarantee detection, closure, isolation of every source or prevention of damage
- Direct-water sensor
- A point sensor reacts where water reaches it, so placement and coverage gaps remain part of the system
- Flow inference
- A system estimates abnormal use from flow, pressure or meter data; learning and thresholds can miss or misclassify events
- Manual recovery
- A documented way to restore or isolate water safely when power, app, network, actuator or cloud control is unavailable
