At first I thought the pump was supposed to dump water outside the house in a potential flooding situation.
This morning I called roto rooter and the guy came out to take a look. He wanted to talk half of the time, so I nudged him along. Eventually we figured out that the pipe going outside the house is just a vent. The pump inside the pit fed into that little pipe along the ground. There is a basement drain nearby. His best guess is that rainwater spills into the pit and then gets pumped into the sewer. (into the pipe leading to the drain.) So here are the questions.....
1) This house is 50 years old. There is no evidence of drain tiles. So what is feed the pit? 2) Has anybody seen a setup like this before? 3) Roto-man said that he doesn't see the floor drain holding water. He thinks there is no trap. Can I do something about sewer gasses without breaking up the floor?Thanks!
