Know when the valve closes
Backwater valve alarms and activation monitoring.

- Permit and inspection aware
- Toronto and GTA service
What to know
Choose a meaningful condition.
The alarm should detect the intended valve movement or high-water condition and communicate it clearly.
Project context
Plan power and notification.
Local sounders, batteries, wired power and remote notification have different failure modes and maintenance requirements.
Owner handover
Test the complete response.
Occupants need to know what the signal means, which plumbing fixtures to stop using and who to contact if the valve does not reopen.
Project checklist
Keep the decision specific to the property.
Use the assessment, authority requirements and written scope rather than choosing from a generic product package.
- Valve-position or high-water alarm review
- Power and battery planning
- Local and remote notification options
- Commissioning and occupant instruction
- Routine alarm testing
