RV Holding Tank Sensors Are The Bain of Many RVers Happy Journeys, Leaving Many Travelers Simply Not Using or Trusting Them.
There are many reasons why your RV holding tank sensors might not be working and we’re going to look at them all.
If you hate reading, here are your key takeaways from this post:
- Through-wall/probe sensors are the most common RV tank sensors and the most likely to fail. The probes extend into the tanks to measure the electrical conductivity between them and the water. The problem is, if anything gets between the water and the probe — you’re not going to get an accurate reading.
- What types of things prevent your sensor from reading correctly? The most common obstructions are; human waste, toilet paper, grease, oils and soap scum buildup.
- How do I know if my sensors need to be replaced? Traditional RV holding tank sensors have long been plagued by accuracy issues. Follow these simple steps to determine if your sensors need to be replaced;
- Rinse and clean tank.
- Clean Tank with chemical treatment to remove any buildup or soap scum.
- If issue is resolved, maintain your tank with a treatment to prevent buildup and enjoy your travels.
- If the issue is not resolved, it might be time to upgrade your holding tank sensors. (Don’t worry. It’s not as bad as it seems.)

Overview of RV Holding Tank Sensors
RV holding tank sensors are essential components of the RV’s waste management system, providing crucial information about the levels of fresh water, gray water, and black water tanks. Well, at least they should…
Accurate sensor readings are vital for effective maintenance and convenience during camping trips. However, these sensors are prone to various issues that can lead to failure and inaccurate readings, impacting the overall functionality of the RV holding system. Sensor issues are probably the most common annoyance that RVers face.
Understanding the common types of RV holding tank sensors and the reasons for their failure is essential for maintaining a trouble-free camping experience.
For instance, consider a scenario where an RV owner relies on the sensor readings to monitor the gray water tank levels. If the sensors are not functioning correctly due to build-up or malfunction, it can lead to unpleasant surprises, such as standing in gray water while showering. A situation like this highlights the significance of accurate sensor readings for ensuring a hygienic and comfortable camping experience.
If you’re dealing with sensor issues, this post will cover the different types of RV holding tank sensors and the factors contributing to their failure as well as how you can correct them.
Common Types of RV Holding Tank Sensors
Through-Wall/Probe Sensors
Through-wall/probe sensors are among the most prevalent types of RV holding tank sensors. They operate by using small metal nubs, or probes, that extend into the tanks to measure the electrical conductivity between them. While these sensors are cost-effective, they are susceptible to gunk build-up, leading to false readings and unreliable performance.
For instance, a study by TheRVGeeks highlights that through-wall/probe sensors are chosen by RV manufacturers based on cost, making them a common inclusion in many RV models. However, their susceptibility to gunk build-up and false readings underscores the need for RV owners to be aware of the potential issues associated with these sensors. By understanding the operational characteristics and limitations of through-wall/probe sensors, RV enthusiasts can make informed decisions regarding the maintenance and upkeep of their holding tank sensors.
External Electrical Resistance Sensors
External electrical resistance sensors offer an alternative to through-wall/probe sensors. These sensors are mounted on the exterior of the tanks and utilize electrical resistance to measure the tank levels. They present advantages over through-wall/probe sensors, as they are less prone to false readings, thanks to their placement outside the tank. However, they come with a higher price tag, making them a less common option in RVs.
Research from TheRVGeeks suggests that external electrical resistance sensors provide a more reliable solution for monitoring tank levels due to their reduced susceptibility to false readings. While their initial cost may be higher, the long-term benefits of accurate sensor readings and minimal maintenance requirements make them an attractive option for RV owners seeking dependable holding tank sensors. Understanding the operational mechanics and advantages of these sensors can help RV enthusiasts make informed choices when considering sensor upgrades or replacements.
External Acoustic Sensors
External acoustic sensors represent a more advanced type of RV holding tank sensors. These sensors utilize ultrasonic technology to provide precise percentage readings of the tank levels without direct contact with the tank contents. While they offer more accurate readings, they are also the most expensive option, making them less common in RVs.
Insights from TheRVGeeks shed light on the enhanced capabilities of external acoustic sensors, highlighting their ability to provide exact percentage readings and minimize the risk of false readings. Despite their higher cost, their superior accuracy and reliability make them an appealing choice for RV owners who prioritize precise monitoring of their holding tank levels.
Reasons for RV Holding Tank Sensor Failure
RV holding tank sensor failure can occur due to various factors, impacting the accuracy and reliability of the sensor readings. One common reason for sensor failure is the accumulation of sludge and the development of struvite crystals, which can interfere with the sensors’ ability to provide accurate readings. Additionally, the use of certain soaps and chemicals can significantly impact sensor performance, causing misreading due to obstructions. Therefore, understanding the reasons for sensor failure is essential for implementing effective maintenance strategies and preventing potential issues.
Research from AskKleenTank emphasizes that the build-up in black and gray holding tanks is caused by tank additives dissolving the tank’s contents into a thick, sticky slurry. This build-up can lead to sensor malfunction and inaccurate readings, highlighting the importance of using compatible tank additives and cleaning products to mitigate these issues. By addressing the common reasons for sensor failure, such as sludge build-up and chemical interference, RV owners can proactively maintain the integrity of their holding tank sensors, ensuring accurate and reliable performance.

Selecting the Right Soap for RV Holding Tanks
When it comes to maintaining RV holding tank sensors, selecting the right soaps and tank additives is crucial for preventing sensor problems and failure. Using the wrong products can lead to sensor issues, ultimately impacting the performance of the waste management system in the RV. Therefore, understanding the guidelines for selecting tank-safe products and the impact of using harmful additives on sensor failure is essential for RV enthusiasts.
Insights from Unique Camping + Marine emphasize the importance of choosing tank-safe products, such as biodegradable soaps and detergents specifically designed for RV holding tanks. These products are less likely to leave behind residues that could interfere with sensor readings, contributing to the longevity and reliability of the holding tank sensors. By making informed choices about the cleaning and maintenance products used in RV holding tanks, owners can significantly reduce the risk of sensor issues and ensure the proper functioning of their waste management system [3].
Additionally, these research sources provide valuable information about the impact of using harmful tank additives on sensor failure. For instance, AskKleenTank highlights that certain tank additives can lead to build-up and corrosion, causing erratic sensor behavior and inaccurate readings.
A huge RV no-no is using bar soap to wash your hands or body. Bar soap, unlike most liquid hand soaps, leave a thick layer of soap scum in your gray holding tank. One shower with a bar soap will impact your sensor readings!
You will find many posts online that recommend using a degreaser to remove bar soap scum, but you will find, like so many of our customers, that most enzyme based treatments and degreasers won’t remove bar soap scum. For this, you will need an actual soap scum remover — not a degreaser.
Therefore, by avoiding harmful tank additives and selecting compatible products, RV owners can proactively maintain the integrity of their holding tank sensors, minimizing the risk of sensor failure and ensuring the accuracy of the waste management system in their RVs. These insights underscore the significance of making informed decisions when choosing soaps and tank additives for maintaining RV holding tank sensors.
