Review on 💧 Valterra T21301VP Horst Miracle Probe - Black Water Tanks, Pack of 4: Optimal Cleaning Solution for Waste Management by Ickey Case

Once I removed the bottom cover and had access to my tanks, the actual process of removing the old sensors and installing the new ones took 15-20 minutes per tank. In some cases it was quite difficult to remove the old sensors so I just put them in the tank which was a lot easier. After installation, all tanks were empty for the first time since buying a motorhome. They were only installed for about a month and hardly used, so an accuracy report will follow later.
