I need some help understanding the electicals on a sewage pump. I happened upon a used one from a friend and it should work as a replacement for my sump pump in the basement for the bathroom that I have added.
He had used this pump for an outdoor water garden and didn't use the switch. I confirmed that the pump works when plugged in directly. The switch is a seperate 110V line with a male/female plug. The pump plugs into this plug.
The switch itself is a black plastic, round can with holes on the bottom. It is fixed to the side of the pump by a bracket. There appears to be a diaphragm inside the can which does operate the pump when I push it by hand. I can also hear and feel a click.
My current pump has an enclosed float switch that likely has a mercury switch inside as the pump is triggered when the float rises and changes angle.
I assume the water pressure will push the diaphragm on the new pump but how much water? I have it in a wash tub but it's not deep enough. Is this entire pump really submersible? I'm concerned about the electrical feeds going into the pump and switch. Do I just need more water depth to trigger?
Any help appreciated!
