Tank sensors are a subject of much discussion among RVers. Tank sensors have been installed in RVs for many years, and RV owners have asked this question for years. Various factors, including toilet paper, human waste, grease, etc., can cause false readings on holding tank monitor panels. Sensors that are dirty are likely to give false readings. It is necessary to clean sensors in order for them to function properly.
RV tank sensors should be cleaned using the following methods:
Prepare a grease-dissolving solution of dish soap and water and let it sit for at least 24 hours before emptying the tanks. Sensors covered in grease and dirt can often be cleaned by soaking them in water. It is also possible to find dishwasher detergents that contain fabric softeners. The holding tanks can be cleaned by filling them half way with detergent and water and taking them to the destination where they need to be cleaned. By agitating the tanks, the detergent is activated and cleaned, just like in your dishwasher. Your sensors should be able to be read correctly at camp. It is possible to increase the effectiveness of both methods by using hot water.
The black holding tanks of some newer RVs are cleaned with rinsers after they’ve been emptied. An RV owner attaches a pressurized garden hose to a fitting on the side after it has been unloaded. Cleaning the black tank’s sensors is accomplished by spraying water around the interior. Your RV can be equipped with a flusher if it does not already have one. The handheld unit can be used to spray water directly on the sensor. Grey tanks may require rinsers if necessary, but black tanks are usually the ones that use them.
It is possible to soften the accumulated dirt with the first method, and then loosen it with the second method.
Taking action before problems arise is the best way to prevent them. Keep your sensors clean by following these steps rather than waiting until they get dirty. It is necessary to use a toilet chemical containing waste digestion enzymes before waste is allowed to collect on the sensors. When flushing your toilet, use plenty of water. Therefore, the chemical in the toilet can perform its function and the waste can be dispersed in the tank. Prior to rinsing, make sure that the container has enough water. Your black tank will have more even distribution of solids when water is suddenly rushed into it when you flush. The bottom of the toilet won’t form a pyramid as a result. Water and black tank flushing are not permitted as frequently for campers without full hookups.
