Tom,
I currently finishing my basement and have heard/read that if the flood rim level of any fixtures is below the next upstream sewer manhole cover that a backwater valve should be installed to prevent sewage backup into the finished basement in the event there was a main sewer line block or other similar malfunction.
With my basement, all the waste pipe runs under my concrete floor out to the main (no pump needed), but my basement floor is lower in elevation than the next upstream sewer manhole cover.
Will a backwater valve help to prevent sewage back up into my basement? I haven't had any sewage backup problems before and the subdivision is only about 10 years old. Also my house sits up higher than any other house between the 2 sewer manholes so I assume one of my neighbors would have the problem before me if it was a main line problem.
The link below is one example I have found.
