Chicago, Ill suburb
First off, I currently have no sump pump, only a cleanout installed and use a stand pipe if needed.
We have had 2 minor floods in our basement (due to our lines clogged with tree roots) we corrected the problem by installing a cleanout and replacing the pipe where the tree roots were forming.
In the last 9 months, we have twice had backups due to excessive rain where the city sewers could not handle the rain.
With these 2 backups, besides the water coming up the floor drain, water appeared to enter from all sides of the basement (filled up quickly to about 2-4 inches). Other than these incidents, seepage has been little to none where I can usually find a cause like clogged gutter overflowing and water seeping through windows rather than foundation.
We are planning on having overhead sewers put in with an ejector pit/pump insalled.
That being said, what's the recommendation on having floor drain tiles installed? - Quite costly and we have DIY shelving (2x12 boards on milk crates) on most perimeter walls. Would be a monumental task to move all this stuff.
We plan to once again carpet with carpet tiles. What's the risk of getting a basement full of water or substantial seepage?
Alternatuively would a backflow system be a better solution compared to the overhead sewer?
Thoughts or comments??
