I'm about to finish my basement and wanted to test the sump pump, but
the cover is sealed with silicone caulk for radon mitigation (there's
a radon pipe coming out of the pit). So my question is that if the
pit is sealed, then if the basement flooded, how would the water get
into the pit for the sump-pump to activate? Would I need to manually
break the seal and open the lid? If I'm out of town when this
happens, am I just screwed? I thought maybe there was a gap between
walls and floor as had been suggested, but it's sealed with the same
caulk as the pit lid. Has anyone seen this before? Am I just missing
something? I've never had water in the basement, but want to be safe
rather than sorry. Thanks
