Undertank filter water level shut off switch
I am custom building an undertank filter for a 20G hex tank. The filter will built into a 5 gallon plastic file box, with a pond pump to return water to the tank and a over the back overflow to drain water to the filter. I am trying to (as much as possible) flood proof the system. I will have check valves on the pipes going in both directions from the filter but I would like to also add a sensor that can shut off the pump if the water level in the filter gets too low (which would indicate that the overflow is clogged and water is not draining out of my tank to the filter).
I have been looking at this
but do any of you have other suggestions?
This tank will be in my living room on a nice floor and directly above the house circut breaker panel so I do want to do what I can to prevent flood issues.
Thanks in advance!
