I have a basement bathroom With a sump located under my cellar stairs (25' from the Bathrm) The sump pump stopped working about a week ago. I have disconnected the piping, sealing them off. I removed the cover and I am in the process of removing the water. I found lite tan matter (feces?) floating around, which I removed as well. My question is how do I check the pump out? The manufacture is FE Myers, Ashland, Ohio The model No. is MW50-1. It was installed in Sept 1999. It has a double cord on it, so I guess its an electric switch in the float, the cords are attached at the plug. I have checked the outlet and it has power. I had some back flow and the sump was over flowing. Should it not have been sealed?
