This is my ATO res, and the hose you see connected to it, started off crystal clear. It turned milky-looking like that after about 2 weeks of use. No tank water ever siphoned back into it, the delivery end is suspended above the tanks waterline because the guy I bought this unit from didn’t include the siphon break piece, so I had to make sure it would never backfill the ATO res.
Should I be worried about this?
