Sentinel Drain Guard

The Sentinel Drain Guard is a sewage backflow protection valve. Highly affordable and easy to install on any floor drain in just one step, the Device is a must-have for every urban homeowner with a basement. Here’s our current reality: weather is becoming more erratic, populations continue to grow, urban building is prevalent and we have antiquated municipal infrastructures that are overburdened. The Sentinel Drain Guard gives you that much-needed peace of mind, preventing sewage backflow from ever entering your house.

Ours is the only product of its kind on the market that stays in an open position by default to allow for unrestricted drainage of regular water discharge from your basement. In a flash, as soon as the Sentinel Drain Guard detects a backflow of sewage from outside, the Device switches to a closed position to protect your home.

The Sentinel is CSA certified, designed in Canada and design patented. Equipped with several redundant features to prevent failure, it’s a device that fits 3” and 4” floor drains and is able to withstand 65lbs of pressure. Without any need for regular maintenance, the Sentinel is reliable and long lasting.
