Hello, My block was recently pummeled by 3.5" of rain in less than two hours. There is a 45" standpipe in the only floor drain in the basement. My neighbors had sewage backup, i did not because of the standpipe. I might have gotten it worse - it seems as though a crack in the floor started gushing water and i got 2" of water in the entire basement. Can that tall of a standpipe cause the pipes to burst or do you think it was just the saturated ground causing the hydrostatic pressure to penetrate the slab? Thanks!
