It rained hard. I got 9″ of water in my basement. plumber snaked main drain, but said it wasn’t too bad. Now everytime it rains hard, basement drains back up, storm water comes in, about 1-2 inches. I disconnected downspouts. didn’t help. Asked another plumber. He says storm drain can’t be cleaned from house and probably trap is clogged, need to dig in yard and fix. Is he right? What’s my next step?? Signed, wet and depressed in michigan
ps: neighbors not having problem. however, we had a new house built next door to us and their grade is higher than ours. we’ve lived here 9 years and have never had this problem before.
