| An alternative might be to pump the basement drains to the only sewer pipe inlet above ground with an air gap that prevents back flow. And put that air gap outside. That way if the sewer backs up enough it will spill outside, not in the basement. But it costs pumping the basement drains all the time. And likely isn't accepted plumbing code.
One hazard of a backflow preventer is that when it works it can force a build up of pressure in the line under the basement floor in pipe not really made for pressure. And while its preventing back flow its also not letting your effluent depart. So it can cause you to make your own basement flood.
