Backwater Preventer for heavy rains/flooding?
I am starting to look into this as we've been experiencing some crazy rains lately -- the last rain was about 8" and I noticed sediment in my basement tub that was left behind by the backing up water. So can anyone tell me what types of backwater preventers there are; any one particular kind stands out? Any I should avoid? I am a newbie with home issues and would appreciate any advice. Thanks very much.
