i have had my vyair 450gpd since january, only using it about once a month.
now i have used it every day last week for about 5 hours a day, and yesterday the auto flush valve started buzzing, and seems to kick in every few minuits flushing the system.

any one else have this system and had similar happenings, or ideas.
i am just about to email vyair and ask there advise. thanks
