How to clean and maintain the RV holding tank sensors?



There is a lot of discussion among RVers about tank sensors. Owners of RVs have asked this question since tank sensors were first installed. Holding tank monitor panels may give false readings due to a variety of factors, such as toilet paper, human waste, grease, etc. False readings are likely to be caused by dirty sensors. In order to function properly, sensors need to be cleaned.

The following methods should be used to clean RV tank sensors:

First method is:

Let it sit for at least 24 hours before emptying the tanks after you’ve prepared a grease-dissolving solution of dish soap and water. False readings can often be resolved by soaking sensors covered in grease and dirt. A dishwasher detergent that contains fabric softeners is also an option. You can clean holding tanks by filling them about halfway with detergent and water, then going to the destination where they need to be cleaned. Similar to your dishwasher, agitation activates the detergent and cleans the tanks as you drive. At camp, you should be able to read your sensors correctly. The use of hot water can improve the effectiveness of both methods.

Second method is:

Some newer RVs come with rinsers that clean out the black holding tanks after they’ve been emptied. As soon as the RV is unloaded, the owner attaches a pressurized garden hose to a fitting on the sides. The black tank’s sensors are cleaned with water sprayed around the interior. You can install a flusher in your RV if it does not already have one. Water can be sprayed directly onto the sensor using the handheld unit. Usually, black tanks are the ones that use rinsers, but gray tanks may need them if necessary.

With the first method, you can soften the accumulated dirt, and then with the second method, you can loosen it.

Third method is:

Don’t wait for problems to arise to prevent them. By following these steps instead of waiting until your sensors get dirty, you can help keep them clean. To break down waste before it collects on the sensors, you must first use a toilet chemical with waste digestion enzymes. Use lots of water when you flush your toilet. This way the chemical in the toilet will be able to do its job and the waste will be dispersed in the tank. Make sure there is enough water in the container before rinsing. When water suddenly rushes into your black tank when you flush, the solids will be more evenly distributed. This will prevent them from forming a pyramid at the bottom of the toilet. Campers without full hookups are prohibited from using large amounts of water or flushing their black tanks as often as those with full hookups.
