I have a Viqua VH410M UV light which includes a UV sensor. There's a solenoid valve that will shut off if the sensor detects less than a certain UV intensity (I think 50%). Every so often the UV sensor trips but the UV light still functions so I do one 12-hour manual override and it keeps working. I've done multiple bacteria tests and never had an issue with that so far (we do have bacteria before the UV light).
I finally figured out that most/all of the times occur when the softener is regenerating. I have a 2-tank system so my best guess is that something in the new tank (regened the previous cycle) is affecting the UV light. Maybe the brine/salt/sodium concentration is too high until some clean water runs through? Any ideas what else may be causing this and how to resolve it? I have a Fleck SXT valve and have several cycle steps I can adjust: brine draw, brine fill, backwash, rapid rinse. Should I increase rapid rinse (currently 10 minutes) and/or decrease brine draw (currently 60 minutes) or something else? Thanks!
