[quote=Brilliant;330523]I really do admire your work. This is just constructive criticism. I was going to ask what happens when the float valve sticks, where is the redundancy? I am adding calcium, magnesium & baking soda directly into my storage container. I was afraid of buildups and imagined a float valve malfunctioning.[/QUOTE0]
I have messed around with this float quite a bit to make sure it would not flood my fish room. I do not see how it could fail, it is all mechanical and no way to clog, all the moving parts are plastic and out of the water. Were you thinking something could get stuck in the moving pieces? Or deposits? I am pretty confident failure is remote. Here is a good pic of the system......DC
