Review on Zoeller 004892 Effluent Pump with Switch for 53-0001: Reliable and Efficient Solution by Mario Portillo

My M53 runs every few minutes under normal conditions. It started working about a dozen short cycles after the first cycle, during which most of the water was pumped out. We replaced almost the entire pump. I thought it was because there was no drainage hole but it stayed after it was drilled. switch replaced. The problem is solved. Installation was easy. There is a video on youtube. The biggest piece of advice would be to take a photo of the old circuit breaker's wiring before you turn it off so you know where it all goes back to.
