1/4 inch float valve to RODI?

[PirateToast]

I'm looking for a solution to auto shutoff the supply to my RODI when my freshwater reservoir is full. I currently have a float valve AFTER my RODI, but that ends up wasting a lot of water, filter life, and electricity in my case.

Anyone have any ideas here? Kind of looking for a float valve that can continue running.

I discovered auto shut off valves are a thing. Fascinating.

Yup, you use a float in the tank and the ASOV to shut down the system.
