Should I install a backwater prevention valve?

What is a Backwater Valve

A backwater valve can sometimes prevent, or greatly reduce, the possibility of a sewer backup. A backwater valve is a fixture installed into a sanitary sewer service lateral either outside or in the basement. A backwater valve is an automatic device which allows water to flow out of the building, but closes when water tries to flow backwards. The unit must be cleaned according to the manufacturer to ensure that the valve closes correctly when needed. During a backup situation, do not add any additional water to the drains by flushing toilets, taking showers, doing laundry, etc.
