How to Test RV Antifreeze Strength
Testing the strength of your RV antifreeze is a crucial step in ensuring the proper maintenance and functionality of your recreational vehicle’s plumbing system. Antifreeze not only prevents freezing in cold weather but also protects against corrosion and scale buildup. Here’s a step-by-step guide on how to test the strength of your RV antifreeze effectively.
1. Gather the Necessary Tools
Before you begin testing the antifreeze strength, make sure you have the following tools at hand:
– A hydrometer: This tool measures the specific gravity of the antifreeze, which indicates its concentration.
– A clean container: Use a container that can hold the antifreeze sample and is free from any chemicals or contaminants.
– A funnel: This will help you transfer the antifreeze sample from the RV system to the container without spilling.
2. Take a Sample
Locate the lowest point in your RV’s plumbing system, which is typically the water heater drain. Open the drain and allow a small amount of antifreeze to flow out. If your RV has a separate antifreeze reservoir, you can take a sample from there. Make sure the container is clean and dry before collecting the sample.
3. Measure the Specific Gravity
Using the hydrometer, carefully place it in the container filled with the antifreeze sample. Make sure the hydrometer is fully submerged and not touching the sides of the container. The specific gravity reading will be displayed on the hydrometer’s scale. Compare this reading to the manufacturer’s specifications for the antifreeze you are using.
4. Interpret the Results
The specific gravity of antifreeze typically ranges from 1.06 to 1.07. If your reading falls within this range, your antifreeze strength is adequate. However, if the reading is lower, it indicates that your antifreeze is diluted, and you may need to add more concentrated antifreeze to restore the proper strength. If the reading is higher, it suggests that your antifreeze is overconcentrated, which can be harmful to your RV’s plumbing system. In this case, you may need to dilute the antifreeze with water.
5. Maintain Proper Antifreeze Strength
To ensure your RV’s antifreeze remains at the correct strength throughout the winter, it’s essential to monitor it regularly. Add concentrated antifreeze as needed to maintain the specific gravity within the recommended range. Additionally, it’s a good practice to change your RV’s antifreeze every two to three years to prevent any potential issues caused by aging or contamination.
By following these steps, you can effectively test the strength of your RV antifreeze and ensure the longevity and reliability of your vehicle’s plumbing system. Remember, maintaining the proper antifreeze strength is key to a worry-free winter RVing experience.
