I am finishing a basement and want to install a shower in a basement. I need to be able to pump the water out of the basement, and do not want a sump type of arrangement to where I have to dig up the floor to install a pump. Is there any kind of a floor-level, 115v or 120v drain pump arrangement available for purchase? It would need to pump up at least 7 feet. Thank You.

Let me turn you on to Zoeller sewerage pumps. Also you can check out their holding tanks and check valves. Zoeller Sump and Sewage Pumps for every sewage and waste water need.
Good luck, tom
