Do you just fill 1 bucket? I fill 5 gallon containers so there is no need for an auto-off unit. You can also invest in a water detection unit that will shutoff the water to the RO unit if you forget to turn off the unit and overflow the container.The thing about the Auto shut off valve (I got one today actually) is that you have to create a hole in the bucket for it. I'm still trying to figure out how I'm going to do that.
You have never said or posted a pic of your current setup. It might be a lot cheaper to just add to your current setup. My setup is over 25 years old and I've added and taken away from it over the years. Back then you were looking at 20gpd setups and there was no such thing as DI.
