My young kids got horns waggled...they bought a house with pool in back and concrete around pool funnels into area covered by deck U shaped. The basement window is in the back of u...when it rains hard..water arches over this window into house...That area under deck is 1 foot deep...cannot grade so that it drains off....Should the sump pump under deck be close to window or in the window well...We have moved a lot of water away by gutter work etc...but if it is a gully washer, they have 3 inches of water in that area of basement....any other suggestions and how big a sump pump, is 1hsp too big...and what brand would you think...thanks so much....Hope this is the last step...for Grandma to do...
