Here are the pics of the slosh guard I had built. The float switches are reed style float switches. I drilled a hole through the top of it, just big enough for the reed to slide into it. I cut a piece of pipe that holds the reed at the level of the water I wanted to maintain. I drilled two holes in the bottom cap which allows the water to rise and fall inside the slosh guard. As the water rises and falls, so does the float ball that slides up and down the reed. That is what activates the float switch. This ball can be turned upside down so it can be configured for either Pump Up or Pump Down activation. The entire contraption hangs on the side/back of the tank where I need to monitor the water level. Could be a sump or the display tank. Doesn't matter. You can see how one is lower then the other. When the water level falls enough to set off the lower one, it starts the top off pump. When the water level rises enough to satisfy the
lower one, it turns off the top off pump. The higher switch was my safety switch. When the ball is down on it, it is active. If the water rises enough to set the higher one off, then the lower one must have failed to turn off the top off pump so the higher one shuts it off.
Here are the pics of everything.
