Let’s see what some customers have said about the Liberty Sump Pump 237

I purchased and started using this device in 2014. 12 months later and it had already disappointed me. I purchased it as a result of the wonderful reviews I read on Amazon. I have used some other pumps in the past and none of them had disappointed me as quickly as this. It worked perfectly well throughout the 12 months it functioned but all that was in the past as I no longer enjoy using it. The rainstorm wasn’t as bad as that of previous years. I would contact the manufacturer to see if the warranty covers this issue.

This sump pump has done an outstanding job for me. I just purchased it recently to swap a pedestal pump which wasn’t carrying out its duties perfectly well. My basement was at a risk of flooding as a result of excessive water and inefficiency of my previous pump. I installed this pump in less than 5 minutes and I used it in a tiny pit of about 10.5” width. This pump is a perfect fit for my needs. It drains water two times faster than my previous pump and it is quite noiseless that it is difficult to hear it running. When I test ran it, I couldn’t believe my luck as I barely heard the sound of the pump.

This is a very impressive pump combined with the fact that it is manufactured in the USA. It is perfect for a 10” sump pit and still gives enough room to avoid switch movement interference. It boasts a special magnetic switch that isn’t prone to water. The switch shaft magnet uses a reed switch sealed in plastic and ensures durability. This pump isn’t prone to leakages either. I am very happy and satisfied with its design which is very much like Gould’s model. The Goulds model is quite costly but boasts a stainless steel exterior for its motor.
