These gauges work accurately all the time: SeeLevel Gauges. I installed a system on my Jayco. These gauges read from the outside of the tanks, and detect a change in capacitance to measure the level of the fluid inside the tanks. But they ain't cheap.

There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.

The theory is sound for low iron content fresh water use. Since you are not likely to find that in your black and gray, forget about it. Fresh is more likely to be accurate as long as you are using softened, filtered water, also unlikely.

If you must... try non-formaldhyde additives for the black and gray. Ice cubes down the commode just before towing. Liberal flush king usage for black and gray. Calgon in the gray(s). Dawn in the gray(s). That should work for a day or two.

After you give up, and you will, try this... leave the gray cracked open. Flush the black 3 or 4 times after dumping so you know its empty and look down the pipe to determine when its full. Repeat till you sell it then start over the week after you get your new one.

The RV industry have been using these lousy sensors for years. Even though there has been technology to measure the fluid in the tanks without using the metal probes the companies have been slow to adopt. Same with led lighting. The last RV show I was at in Feb. this year, Open Range was the only trailer I went in that came with led lighting. It comes down to money and what they think the consumer will be willing to pay for. Did you notice how fast the industry adopted to the drawers that are able to fully pull out. They push this really hard as a selling feature but the upgrade cost to them was negligible. Probably had no choice. I truly think the roofing system could be made to better withstand the chance of having a leak after some time. But then would you ever have to buy another trailer.

X3 on the Horst probes. Know someone who had them installed, and never had another false reading. I will be putting these in sometime before the next camping season.
