For 15 yrs I've always manually filled my tank with the RODI water that I make. Then I came across this inexpensive 1/4 in valve that I could put at the end of my RODI line and not have to manually top off anymore. Do any of you use these? Too risky for failure, leaks, etc? Ok for my RODI unit to have that pressure continously? It's been hooked up for a day and everything is fine so far, and I have audible leak alarms... But I wonder if these shut off types have had issues? TIA!
