I have a typhoon 3 air water and ice RO/DO system. It has a built in ASOV which I connected to a float valve in my 55 gal barrel. The problem is even when it shuts off the RO/DI the system continues to make waste water. I called air water n ice and they said that there ASOV should also shut off waster water. They told me to flush system which I did but didn’t work. I read a thread on R2R about using solenoid valve in wAter input and avast marine pressure switch output. My question is can I just install these vss as lies with my present system? Any other suggestions will be greatly appreciated.
