Drip float valve

[Charney]

I’m looking for recommendations for a float valve set up for my drips. In the very odd chance, the drain line gets clogged. I really rather not drill the tanks for this any suggestions?. to be clear this is to shut off the drip

I tried this once with a solenoid, a small float switch and a twelve volt power supply. It was total overkill, and difficult to maintain. I have never had much luck with solenoids, and would not recommend.

I simpler thing might be a simple stopcock, the mechanism that used to be in toilets. Very simple, the stopcock ball rises up and closes the valve. They are however quite big. I do not know where you would get a small discrete one.
