This new improved product is the ultimate in detailed measurement and will measure 3 or 4 tanks up to 1 8.
Before we get started on how to restore rv tank level monitors in your rv s gray tank let s briefly discuss what is happening to make them malfunction.
The waste tanks are more prone to sensor issues simply because of the nature of the materials contained than fresh water tanks so we will focus on those.
When water inside the tank hits the metal nub it completes the electrical circuit and turns on the colored lights located in your rv monitoring panel.
Both tanks contain enough biological material to connect the sensors creating the inaccurate readings.
The sensors are external and will not affect your readings by sewage buildup.
The sensors are placed at equal intervals in the black water tank like 1 3 2 3 and full.
How it works.
