I need to replace my 20 year old sink pump on a basement utility sink, I need to use the direct mount kind since there are no vent pipes in the basement. I see 3 manufacturers make these HARTELL LTA-1-ABC , Bur Cam Pump #300514W and Flotec Automatic Utility Sink Pump. Anyone have any experience with these manufacturers? the Burcam is about $150, while the other 2 are close to $250.
