What are RV Tank Sensors?
RV tank sensors are devices installed in your RV’s holding tanks to monitor the levels of waste or water. They are typically placed at different points along the tank walls to provide readings indicating whether the tank is empty, partially full, or full.
Most RVs have sensors for the fresh water, gray water, and black water tanks, allowing you to track usage and prevent overflows. These sensors are crucial for managing your resources efficiently while on the road, ensuring smooth operation and helping to avoid potential issues such as overfilling or system malfunctions.
Importance of Cleaning RV Tank Sensors
Keeping your RV tank sensors clean is vital for maintaining accurate readings and ensuring the proper functioning of your RV’s tank system. When residue, waste, or build-up accumulates on the sensors, it can interfere with their ability to provide precise measurements. This can lead to false readings, such as indicating that a tank is full when it’s actually empty, or vice versa. Such inaccuracies can disrupt your travel plans by causing premature emptying or unexpected overflows.
Regular cleaning helps to remove any debris or blockages, allowing the sensors to function as intended. Additionally, maintaining clean sensors can extend their lifespan, reducing the likelihood of costly repairs or replacements. By prioritizing the cleanliness of your RV tank sensors, you not only avoid unnecessary headaches but also ensure a more efficient and worry-free RVing experience.
10 Methods How to Clean Rv Tank Sensors
1. Use a Commercial Sensor Cleaner
One of the easiest and most effective ways to clean your RV tank sensors is to use a commercial tank sensor cleaner. These products are designed specifically to break down the residue, grease, and scale that can accumulate on the sensors over time. Commercial cleaners usually come in liquid form, and you can pour them directly into the tank through the appropriate inlet.
After adding the cleaner, fill the tank with water and let it sit for several hours or overnight, allowing the cleaner to dissolve the buildup. Afterward, empty and flush the tank thoroughly to remove any remaining cleaner and residue. This method is highly effective for both black and gray water tanks and is gentle on the sensors.
2. Clean with White Vinegar and Baking Soda
If you prefer a more natural cleaning solution, white vinegar and baking soda can work wonders to clean RV tank sensors. This combination is great for breaking down organic buildup, soap scum, and mineral deposits without the use of harsh chemicals. To clean the sensors, mix a cup of baking soda with a gallon of white vinegar and pour it into the tank.
Add a gallon or two of water and let the mixture sit for several hours. The chemical reaction between the vinegar and baking soda will help loosen buildup from the sensors and walls of the tank. After the waiting period, drain the tank and flush it with clean water to remove any leftover residue. This method is gentle yet effective and environmentally friendly.
3. Use a Tank Cleaning Wand
A tank cleaning wand is a handy tool that can help clean both the inside of the tank and the sensors. These wands typically have a rotating head and multiple nozzles designed to spray water in different directions.
By attaching the wand to your RV’s sewage outlet, you can direct high-pressure water into the tank to clean off any debris or buildup that may have accumulated on the sensors. The pressure from the wand is often enough to loosen and dislodge any substances that are causing inaccurate sensor readings. When using a cleaning wand, make sure to flush the tank thoroughly afterward to ensure no residue remains.
4. Run a Clean Water Flush
A simple and effective method to clean RV tank sensors is by performing a clean water flush. This method involves filling your black or gray water tank with fresh water and letting it slosh around for a while as you drive your RV or let it sit for a few hours. Afterward, drain the tank completely and repeat the process.
The movement of the water will help dislodge any buildup on the sensors, and flushing the tank multiple times will ensure that any residue is removed. This method may not be as effective for stubborn buildup, but it’s an easy way to clean the tanks without needing specialized products or equipment.
5. Use a Sensor-Specific Cleaning Solution
Many RV owners recommend using sensor-specific cleaning solutions that are formulated to remove buildup from the sensors without damaging the tank. These cleaners are typically more effective than general-purpose cleaners and may even help prevent future buildup.
To use a sensor-specific cleaning solution, add the recommended amount to your tank, followed by fresh water. Let the solution sit for the amount of time suggested by the manufacturer (usually a few hours or overnight). After the solution has had time to work, drain the tank and flush it thoroughly to remove any cleaner residue. This method is particularly useful for heavily fouled sensors and is widely available at RV supply stores.
6. Use a Tank Cleaner and Deodorizer Combination
Sometimes, buildup in the RV tanks can be accompanied by foul odors. Using a tank cleaner and deodorizer combination can help address both issues at once. These products are designed to remove the organic waste and debris that clog the sensors while also neutralizing odors inside the tank.
To use, pour the cleaner into the tank, add water, and allow it to sit for several hours. This product often works best when left overnight to break down stubborn waste and clean the sensors. After the waiting period, drain the tank and rinse it with fresh water. In addition to cleaning the sensors, this method will leave the tank smelling fresh.
7. Clean Using a Manual Scraping Tool
For a more hands-on approach, you can use a manual scraping tool to physically remove debris and buildup from the sensors. These tools typically consist of a long, flexible handle with a scraping head that allows you to manually clean the sensors through the sewage outlet.
This method requires some physical effort, but it can be highly effective in removing thick sludge or hard deposits that other cleaning methods might not reach. Once the buildup is removed, flush the tank thoroughly with clean water to wash away any leftover debris.
8. Check and Clean the Sensor Connections
While cleaning the sensors themselves is important, it’s also crucial to check the sensor connections. Sometimes, the issue may not be with the sensor but with the wiring or electrical connections that send the sensor readings to the monitor. Over time, these connections can corrode or accumulate dirt, leading to faulty readings.
Inspect the sensor connections for any visible signs of corrosion, rust, or dirt buildup. If necessary, clean the connections with a wire brush or contact cleaner. After cleaning, reconnect the wires, and test the sensor to ensure accurate readings.
9. Use a Tank Cleaner Additive
Tank cleaner additives can be added to the water in your RV’s tanks to help prevent future buildup and maintain the performance of the sensors. These additives break down waste and grime in the tank, keeping the sensors clean for longer periods. To use a tank cleaner additive, pour the recommended amount into the tank, then fill it with water.
Let the solution sit overnight to work its magic. After the waiting period, drain and flush the tank thoroughly. Using a cleaner additive regularly can help keep the sensors free from debris and prevent the need for more intensive cleaning methods.
10. Replace Faulty Sensors
If all else fails, and the tank sensors continue to provide inaccurate readings even after cleaning, it might be time to replace the faulty sensors. Over time, RV tank sensors can become worn or damaged, especially if they have been subjected to heavy buildup or misuse.
If you suspect that your sensors are beyond cleaning, consult your RV manufacturer or technician to find suitable replacements.
