Approx 50yr old split level house have lived in for past 18+yrs. Only twice in all these years have we had flooding in the lower level, once 5 yrs ago when a storm drain had been blocked & opened up, & last this past Dec. during the heavy rains. This weekend has been near 40 degrees so there's some thawing of all the snow we have all around, & we are seeing some seepage through the floor drain in the laundry room & the downstairs toilet doesn't want to flush. We have just replaced carpet down there from the flooding in Dec. Would appreciate any suggestions on what we should be doing before we have to deal with all this melting snow & spring rains!
