Now most of you know I work for Basement Systems, so I know a thing or two about sump pumps for basements or crawl spaces. I'm not an expert on this subject matter of course, so I bring the expert to you.
Larry Janesky is the owner of Basement Systems and he is the EXPERT!!! So, here is a pump review by the industry leader :)
Check out the official sump pump comparison page at Basement Systems web site. We have one more video addition to the one above. That video talks about sump pump motors.
