BUYER'S GUIDE

How do I know if my propane regulator is bad on my camper?

There are a few symptoms that indicate your regulator isn’t working properly. First, you may notice that the flame on burners has turned from blue to a lazy yellow. Burners also tend to be louder when the regulator isn't working properly. In extreme cases, you may also notice heavy soot or rust deposits on or around the burners themselves.

When should I replace my propane regulator?

Most regulators last between 15 and 20 years depending on how you mount and maintain them. Keeping your regulator covered from the elements is critical to ensuring a longer lifespan. You can also have an RV or propane service technician test your regulator once a year to check if it's still maintaining the correct pressure. If the pressure isn’t being maintained consistently, the regulator needs replacing.

Do I need a high or low-pressure propane regulator?

That depends on the RV accessories that run on propane for your camper, 5th wheel or RV. The bigger the system, the higher the BTUs/hour flow rate needs to be on your regulator. For example, most 100lb dual tank propane systems need a regulator with a minimum flow rate of 200,000 BTUs/hour.

What happens when the propane regulator fails?

Your primary tank will run out of propane and the regulator will fail to switch over to the reserve tank. All propane accessories in your RV or camper will shut down, and you will need to cut off the service valve, install a fresh primary tank, and turn the system back on.

Worst case scenario, your regulator may be leaking. Newer RVs come with a built-in sensor that detects propane leaks and irregularities in gas pressure. It’s usually linked to the propane service valve and cuts off immediately when it detects a leak. It also sounds an alarm so you know that there is a leak present.

CONCLUSION

After researching all of these regulators thoroughly, I find that Flame King KT12ACR6 is the best overall 2-stage automatic propane regulator. This model is built of high quality materials, has a weather resistant cover, and pushes out sufficient BTUs/hour to support most small to medium size RVs, campers and 5th-wheels.  If you need a replacement 2-stage regulator, get a Flame King KT12ACR6. I am confident it will keep your propane system running smoothly for many years to come.
