A system that hasn’t been used for a little while or appliances that don’t start may indicate that you need to purge your systems.
It may seem difficult to blow out air from your RV propane lines, but it is really a very simple procedure.
Now, let’s discuss how to purge RV propane lines with a complete guide.
How to Purge RV Propane Lines?
Purging air from the propane system of your RV is a simple and straightforward process. Let’s follow the below steps:
- The first thing you need to do is open your propane tank valve. You should be able to turn it counterclockwise as far as the valve will allow.
- Start your stove by lighting a burner. While the gas begins to flow and remove the air from the system, it may take some time for the burner to light. Turn on all the burners on your stovetop once you have lit the first.
- The flame of the burner should be kept in mind. After the propane lines have been purged, the flame will burn steadily and become blue. Disconnect the propane line.
- Last but not least, ensure that any other propane-powered appliances in your RV are functioning properly. Your stovetop may have been connected to a different gas line and needs to be purged.
How Does Air Get In RV Propane Lines?
A sealed and pressurized propane system is installed in your RV. If it’s sealed and pressurized, how can air possibly get inside?
There is a possibility that you will have trouble starting gas appliances if you completely empty your propane tank (or Hook Up an External Propane Tank to RV)and replace it. Your propane system may start to wear out as it ages, and the rubber propane hoses may be loose or the propane connection may be malfunctioning.
Your RV propane detector may not even pick up these leaks because they are so small. You will likely find that starting propane-powered appliances is difficult due to air in the lines if your propane leaks and is stored for a long time.
Your propane system should be checked by a certified RV technician if there is a constant problem with air in the lines.
When Should You Purge the RV Propane Lines?
Every time you leave your RV and plan to use your propane system, make sure that you purge your propane lines of air. You should also do this after just pulling out of storage. Replace your propane tanks after every replacement as well.
The following problems with your gas appliances may require bleeding your propane lines:
- Instead of blue flames, the stove-top flames are orange
- RV furnaces, refrigerators, and heaters cannot be ignited
It is easy and free to bleed propane lines if you are experiencing any of the above issues. Depending on whether the problem persists, you might have a bad RV propane regulator, the RV propane stopped flowing altogether, or you could have other issues.
What Happens if You Don’t Purge a Propane Tank?
When propane tanks are being shipped from one altitude to another, they are usually filled with some air to compensate for pressure changes.
If a propane tank isn’t purged of air, what happens? If your propane tank is rusted inside, or your regulator freezes up, it can be difficult to refill it.
A cylinder that has not been properly purged, on the other hand, makes it harder to detect a leak since you cannot smell it. It is essential that a licensed professional purges a brand new propane tank.
Do propane lines need to be purged?
Every time you plan to use your propane system while camping, you should purge your RV propane lines of air. You should particularly do this if you just removed it from storage. You should also do this after every propane tank replacement.
How long does it take to bleed propane lines?
In order to bleed propane lines, start the gas and let the air out from 0 to 10 minutes depending on the size of the lines.
