In the main panel in my house I have a circuit breaker labeled sump pump. I looked inside the basement but there was no sump installed anywhere. I went outside of my house and found a round green lid (nothing to do with my septic) and when I unscrewed it, I found it down about ten feet (no water down there). Why would this sump pump be installed outdoors and how to I know if it is working or how will I know if it goes bad? Thanks
