I hooked my sump pump up to the storm sewer (with the village's assistance) years ago. Now, my neighbor wants to tap into my line. I am afraid this will overwhelm the pipe and cause problems for me. The pipe coming out of the house has an air gap, so I assume the first thing that would happen would be water pouring out next to the foundation. I am afraid that too much water in the pipe could burn our my pump and flood my basement. His landscapers are here now digging trenches and I have asked the village to send their inspector over ASAP. Any thoughts or suggestions?
