Tunze osmolator problems

There are plenty of ways to test the sensor by simulating a decrease in water level. If you have an in sump skimmer just raise your water level in the skimmer that will decrease the level in the sump. As far as testing the sensor in another artificial way I wouldn't know. I know my first tunze ATO went nuts within a couple of months and they replaced it and I haven't had an issue with it for years.

Ya, I needed perhaps an electrical way to test, otherwise the return chamber level where the sensor sits would have been fine

I talked to Tunze's Canadian contact, a Phil Gilbert with Xenia North American INC, and he's sending me a new sensor. All I had to do was tell him I got it from J&L and he said he's putting it in the mail that day. Sweet customer support.

if u move the float switch (by hand) and don't hear the relay in the brain click it's probably dead.
