    I recently purchased a house with a full bathroom in the basement. It is about 10 feet from the sewage pump so I always assumed that it went into that basis and then was pumped out. Today I was bored and let the water run in the bathtub for awhile and I never heard the pump go on.

    My main sewer line is about 3-4 feet below the first floor, so essentially at around head level in the basement. Is it possible that the bathroom in the basement goes directly to the sewer lower down or does it have to go to a basin to get pumped out?

    Thanks

    It probably goes to the sewer and the pump is just a groundwater receiver.

    I have a separate pump for rainwater. This sewer pump goes right to the sewage line.

    If the main sewer line is head height in the basement, how would the basement tub drain up to it?

    The only way would be the sewer pump but when the tub is on the pump doesn't go off.

    Depending on the size of the basin and the capacity of the pump, it might only run for 10 seconds for every 10-15 minutes the water is running.

    Missed that. I thought he said the sewer line was below the basement floor, not the first floor. In this case the only place it can drain is to the sewer pump.
