Three Lines of Defense
Valve Closes Automatically
In the event of a sewage drain back up, the Mainline backwater valve closes to protect the home from flooding.
Continued Use Causes Damage
Continued water use in the house, while the Mainline valve is closed, forces water to back up into the basement and cause damage.
Alarm Alerts Instantly
The Deluge flood alarm works with the Mainline valve so floods are noticed quickly, preventing damage to the household.
Simple Installation
- Insert and tighten the Deluge flood alarm cap into the Mainline backwater valve.
- Connect the Deluge flood alarm chime box to the nearest wall.
Backwater Flood Alarm Questions
- What is a Deluge backwater flood alarm?
- Deluge is an audible flood alarm that installs on a Mainline backwater valve. When the valve closes during a sewer backup, the alarm alerts the household so they can stop using water and call their plumber before the basement floods.
- Which backwater valves does Deluge work with?
- Deluge is purpose-built for Mainline Fullport backwater valves. The alarm cap threads into the valve; the chime box mounts on a nearby wall. No complex wiring is required.
- How is the Deluge flood alarm installed?
- Insert and tighten the Deluge flood alarm cap into the Mainline backwater valve, then connect the chime box to the nearest wall. Most plumbing professionals complete the add-on in minutes during a valve job.
- Why should plumbers offer a flood alarm with every valve?
- Pairing a Deluge alarm with every Mainline valve adds trade-priced revenue per job, reduces emergency flood callbacks, and positions the contractor as prevention-focused rather than repair-only.
- What should a homeowner do when the alarm sounds?
- Stop using water in the house and call your plumbing professional. The Mainline valve has closed to block sewage backup; continued water use is what forces wastewater into the basement.
Floods Are Becoming More Frequent
Climate change is driving more intense rainfall and overloaded sewer systems. Basement floods from sewer backups are on the rise across North America, and a single event can cause tens of thousands of dollars in damage.
A Deluge flood alarm is a small, one-time investment that gives homeowners and plumbing professionals early warning when a backwater valve has closed, preventing the continued water use that turns a manageable backup into a disaster.
