Barbell,

You managed to wash the contaminate off one of your sensors, but don't get "used to" the correct reading. All it takes is one small bit of toilet paper or other "solid/semi-solid" material to lodge in the sensor contacts and you'll be right back where you were.

I don't know of anyone who has "conventional tank sensors" and maintains correct readings for any great length of time. We all pretty much learn to ignore the tank status monitor and just judge by time or the way the toilet sounds when flushed to tell when we're getting close to full.

There are a couple of "outside mount" sensor systems that eliminate the problem of "fouled sensors" but they cost more than most of us are willing to pay for a system that we've learned to ignore LOL

If you do a search for "tank sensor" on the forum, you'll get a pretty detailed accounting of what other people have faced and what they do to resolve (or live with) the issue.
