All systems working ok, but gray water reads empty all the time regardless of actual conditions.. Any suggestions for fix?

I can win any argument on any subject. People know this and steer away from me at parties. Often as a sign of their respect, they don't even invite me.

If you have a Micropulse system, they are notorious for this. My fresh water no longer registers, gray water is always empty below 50 degrees and black water works no matter what. I think they have to cut into the belly pan to get to the sending units.

Some have converted to the Sea Level system (expensive). You can use the search feature to search for threads on Micropulse. There are a multitude.

I fiddled with the Micropulse for 5 years. Finally figured out a good system for reprogramming, but it inevitably goes out of calibration at least twice a year.

The only true fix is replace with a SeeLevel system. I did that swap this spring. I now can rely on the readings.

Did it myself, so it wasn't too expensive...$250ish IIRC.
