How to Bleed Air From Your RV’s Water Lines
Purging air from your RV’s water lines is a relatively straightforward process. You only need to find the source of the air pockets to continue and end the process as efficiently as possible.
Things You’ll Need
You don’t need any special materials to remove air from your RV’s water system. Additionally, you don’t need extensive mechanical experience.
After finding the source of the air pockets, you should fill your rig’s fresh water tank. In turn, the pump (once turned on) should allow proper circulation throughout the system. From that point, the following steps depend on certain specifics.
Step 1: The Straightforward Method
In many cases, turning on the water pump allows water to flow through the system. Allow the faucet to blow and sputter water, removing air pockets in the process.
At times, water won’t flow immediately upon turning on your RV’s faucet. It might sputter, but give it a few moments and it should start flowing normally. The next step is to simply turn off the faucet and most of the air should be out of the pipes.
Step 2: The Systematic Approach
After using the straightforward approach, some RV water systems might still sputter after every few minutes. If so, you need to proceed to a more efficient method of purging air from the vehicle’s water lines.
Start by connecting your RV’s water line to a pressurized location, such as a nearby faucet. Then, open all of the rig’s water outputs, which include the kitchen faucet, outside faucet, and bath or shower.
After a minute or two, the sputtering from the water system should stop. You’ll know when all of the air in the water lines is gone if the water flow returns to normal.
Step 3: Remove Air from the Water Pump
In some cases, air can still return to the water lines after purging the system using the systematic approach. If this instance happens, you should check your water pump for gaps and holes, and seal them.
Once sealed, disconnect the output pipe from the water pump. Next, attach a sufficiently long hose to the pump. Fill a reservoir with about 12 ounces of water while holding the other end of the hose to the water pump.
Cover the hose’s end with your finger and turn on the water pump. Water should hit your finger after a while, and doing so will help remove the air that’s still in the container. After this, turn off the pump and reconnect the outgoing water pipe.
Step 4: Remove Air from the Water Heater
If air bubbles are trapped in your RV’s water heater, the best method is to purge air from the tank as a maintenance operation. Although this process can take longer than the other techniques, it’s going to help lengthen the longevity of your rig’s water system.
Start by ensuring that the heater is off. Additionally, make sure that the water tank is cool or at room temperature (which might take about an hour).
Next, turn off the water mains, but open the faucets to help relieve pressure from the system.
Then, turn off all pressure release valves in and around the vehicle. Wait until the system drains the water completely. Close the faucets and valves once water is no longer coming out of them. This process should also remove the air pockets from the heater.
Step 5: Additional Notes
You can also clean the parts of your RV’s water system while you’re purging air from the water lines. That way, you can ensure that your rig’s water system is functioning at optimal efficiency.
How Does Air Enter an RV’s Water Line
Air can enter an RV’s water line from different areas. These locations include the following:
- Water pump: Cracks or gaps in the water pump will cause air pockets in the pipes.
- Freshwater hose: Small incisions or holes can allow air to enter the water line.
- Water heater: Another possible cause for air pockets in the water line is a loose water heater plug.
How to Prevent Air from Getting Into Water Lines
As the old saying goes, ‘Prevention is better than cure.’ Hopefully, you only need to bleed air from your RV’s water lines infrequently. With that said, here are some tips to help prevent this issue from returning to your rig’s water system.
- Do routine plumbing maintenance. Your camper or travel trailer’s water lines aren’t invulnerable to harm. Check the water system at least once a month to ensure no loose connections, leaks, or excess air exist.
- Install a water pressure regulating device. This device will help you monitor the amount of water pressure in the system. Also, you can use this tool to reduce the pressure if it gets too high.
- Check the water filter. If this part becomes dirty, air and other filthy substances can seep into the water reservoir.
- Drain the water from the fresh water tank. Consider draining the water from the container on a schedule. But refrain from removing all water. In turn, you won’t need to purge the water lines every time you operate the water pump.
