Very professional and dependable.
Ron Monk was excellent. In hindsight it would have been nice to know why he recommended the M53 pump rather than the pump that is one level up (250,000 cycles vs. 500,000 cycles)...but we did not ask.
Based on internet research I determined that I wanted a Zoeller pump. Clarke Basement Systems advertised that they install Zoeller pumps.
Thank you very much!
