I opened my flush valve on my RO/DI the other day and completely forgot that it was open. Two days later, my fiance called me at work to tell me that my water purifier thingy is making a weird noise. I told her to go down and look at it and I could hear a kind of srceaching noise as she got close to it. I had her shut it off and when I got home I turned it back on and every thing seems fine. The water is still reading 0 on my tds meter. Did I do any harm to it by leaving the flush valve open for two days?
TIA,
