I have a full bathroom in the basement wich everything empties into a sewer ejection pump. I would like to install a laundry sink. Can I drain that sink into the sewer ejection pump from the top.the pump is about 15 feet away from the new sink.

Do you have a connection om top of there pit or do you plan on destroying the seal? I hope ypu weren't planing on tieing the drain into the pit vent. Let me know your plans.
You do realize that the sink will have to be vented don't you? Regards, Tom
