Sounds like you have under ground sewers in your home, meaning the sewer pipes go down through the basement floor?My sewers here are"over head" sewers where the sewer pipes that come from the up stairs run just below the joists and then go out side through the side of the foundation about 5ft from grade, well below the frost line.

If that's the case then you won't need an ejector pump. If I were to put in a basement bathroom all of the sewage must be "ejected" through the ejector pump up and out to the city sewer system. That's another reason why I don't want a bathroom in my basement. If that pump ever fails............Someone has to pull it out and install a new one.[:'(]I have plenty of bathrooms upstairs, I don't need another.

But, the up side is overhead sewers keep waste from backing up through the floor drains in the event of flooding. The only drain in my floor is plumbed directly to the ejector and it's there in case my water heater fails.

I was talking about basements with my brother who lives in NC when I was down there for Thanksgiving. He was telling me that basements are not as common down there. He has one because being a transplant (19 years) he was always used to having one. He said it definitely reduced the number of prospective homes when he was looking to buy.
