Is my float switch broken? It goes clunk...
A friend gave me a used battery backup sump pump. The float with the switch in it goes 'clunk' when you shake it, and only seems to go on if you jiggle it, not if it just rises with the water level. The float switch on my original pump doesn't clunk when you shake it. Is the other one broken?
I don't know what's inside there, maybe some kinds do go clunk. I'd just go buy a new one except the hardware store wants $50 for it and I'm not inclined to spend that unless it's really broken.
