    I have a full basement with a full bathroom and a wet bar that empty into a septic sump basin with sewage pump that pumps up to to the main discharge drain which empties to my septic system.

    Due to some original install issues and piping location issues, I am re-doing the discharge pipe. I have found a couple of videos that suggest drilling a small hole (1/8-3/16) in the discharge pipe about level with the top of the pump. My pipe does NOT have one currently in it and I am curious about the need for this and it if helps, etc?

    If the bleed hole is required it will be specified in the pump installation instructions. Some pumps have it built into the discharge section of the housing.

    its purpose is the allow the pump to discharge an air bubble if the pump does not shut off in time and pumps the pit dry. Otherwise, the pump will "run dry", not pump the water, and damage the shaft seals.
