Sands in French Drain
With the recent Hurricane, Irene, dumping a lot of rain in NY/NJ area, my basement is flooded. I do have a french drain with the sump pump. But there aree severl spot inside the french drain where the water comes out strongly with a lot of sands. The sands block the french drain itself and water has no place to go but flooded the basemanet.
What is the problem (I thought the french drain is supposed to handle the blockage)? What can I do?
Thanks for any help in advance.
