Sentinel Drain Guard
Changing weather patterns and severe rain storms combined with the increased failure of aging municipal infrastructure are causing expensive flood damage in urban basements. Water damage has surpassed fire as the leading cause of personal property losses. Typical Insurance policies have a $2000.00 deductible for sewer backflow damage, so even a deductible is expensive – but a personal property loss can cost more than money! Professionally installed mainline sewer backflow prevention devices are very expensive and require digging through the basement floor. Regular professional maintenance is required to prevent failures.
SENTINEL backflow device is an inexpensive, easy to install device that any homeowner can purchase and install themselves in one simple step. When SENTINEL is installed in your basement floor drain it will guard against sewage backflow from entering your house causing thousands of dollars in damage and loss of sentimental property. SENTINEL has multiple redundant features to prevent failure. SENTINEL is a normally ‘OPEN’ valve permitting unrestricted drainage of normal water discharge occurrences

A Sentinel is a sentry, a guard, positioned to protect an opening from the entry of unwanted intruders while simultaneously allowing unrestricted departures through the same opening.
