LF well used RO system

[Ryanerickson]

Coming from a plumber hooking up ro waste to washing machine as far as I know is not easy most people use hot water to start with so that ends that idea right away but even with cold wash you would need a large expansion tank and a bunch of new plumbing installed even with that I doubt it would have the pressure and volume needed to operate properly . Other options are using in garden I know people that drink it but our water out of tap is 8-9 ppm so pretty clean.
