Twice now I've turned on RO water to fill my kettle only to forget. Luckily our RO system only has enough storage to generate about 14 gallons of water in ~12 hours so I've not (yet) overflowed my 15 gallon kettle but it was time to do something. I previously tried an expensive electronic solution with a flowmeter that was wildly inaccurate. I thought about a simple float switch with a solenoid but after some thinking came up with this contraption using parts I had lying around that reuses the recirculation port I have in my lid. The bottom piece of tubing is hiding a straight-through John Guest-style fitting. It happens to work out that clamping the QD down squeezes the gasket into the 1/2" OD stainless tubing holding it snugly, but not so much I can't make adjustments, the small piece of tubing just keeps it from sliding around during installation. I just have to pop the blue tubing apart at the valve to install.
