Background: Downspouts and sump pumps in the subdivision connect to the storm sewers. The main sump pump discharge goes through the basement foundation about 4 feet below grade and then turns 90 down about 8 feet away from the foundation.
According to the hydraulic backup sump installation instructions, (which I actually read!) it says that connecting to the main sump's discharge inside the house is against code. I don't want to follow the standard installation instructions and drill through the rim joist because I will end up recycling the water especially given that there is no french drain around the foundation. It would be difficult to lay a discharge pipe exposed to daylight as the runoff will end up in my neighbor's yard. In addition there's no realistic way to create a dry well as you hit bedrock less than 2 ft down. (They must have used a jackhammer to trench the main discharge)
Question: Can I "wye" into the main discharge outside the foundation? Or should I dig down and find where the main discharge connects to the storm sewer lateral and connect to that? Any other suggestions? Thanks!
