I am thinking of connecting the hose from the sump pump into the main sewage drain in the house. The man at home depot says I have to put in a trap. He says the line should go up to the basement ceiling height, drop down at least 3 feet then back up to 7' before going into the main drain pipe. He says the trap will keep "deadly gases" from leaking into the house. Is this plumbing thing as dangerouse as he made it sound and do I really have to put in a trap instead of going straight up and turn 90 degrees straight into the drain pipe. There is a back flow restrictor near the pump.

Yes, you need a trap to connect the pipe into the sewer line. Why you need a trap as big as he says, I don't know. I would think a standard trap would work.

No, you should not do this project. In my area this is forbidden by code and they are actaully inspecting houses to make sure that downspouts, sewers and sump pumps are not connected to the sanitary sewer system. The problem is that during heavy rains the sanitary sewer system overflows. Extend the sump pipe into the yard or street, not to the sanitary sewer.
