How Do You Blow Out An Rv Water Line With A Compressor?

Hey there fellow RV enthusiasts!

As the colder months approach, it’s important to prepare yourrecreational vehicle for winter storage. One key step in this process isblowing out your water lines to prevent any potential damage fromfreezing temperatures.

Using a compressor to blow out your RV water line may seemintimidating at first, but with the right tools and techniques, it canbe done easily and effectively.

In this article, we’ll go over the steps you need to take to safelyand efficiently blow out your RV water line using a compressor.

So grab a cup of coffee and let’s get started!

Preparation

Before blowing out an RV water line with a compressor, it isimportant to properly prepare the system. As an RV maintenancetechnician, I recommend starting by repairing any leaks and checking allconnections for tightness. This will ensure that air pressure can bemaintained throughout the entire system.

Next, drain all of the tanks in your RV to remove any residual waterthat may be left behind. It’s crucial to winterize your system beforetemperatures drop below freezing, as this can cause serious damage toyour pipes and fittings. By taking these steps, you’ll make sure thatthere’s no chance of frozen water causing issues down the road.

Once everything has been drained and checked, it’s time to beginmaintaining pressure and shutting off access points one at a time. Thisprocess ensures that each section of pipe receives adequate airflowduring the blowout process without wasting compressed air on areas whereit isn’t needed.

Shutting Off Water Access

Ok, let’s start with shutting off the water supply. I’ll walk youthrough the process of disconnecting the waterlines so you can blow outthe lines with a compressor.

Shutting Off Water Supply

When it comes to shutting off water access in your RV, one crucialstep is shutting off the water supply.

As a maintenance technician, I recommend turning off the main valvethat supplies water to your RV.

It’s also important to open all drainage valves and faucets torelease any remaining water pressure from the system.

This ensures that no residual water remains in the pipes during thewinterizing process, which could lead to freezing and damage down theline.

By taking these steps before blowing out your RV water lines with acompressor, you can ensure a thorough winterization and prevent costlyrepairs in the future.

Disconnecting Waterlines

Now that we’ve covered shutting off the water supply, let’s move onto disconnecting waterlines.

As a maintenance technician, I highly recommend doing this step as itensures all water is removed from the RV’s plumbing system.

First, locate and open all drainage systems in your RV to release anyremaining water pressure.

Next, find and close any bypass valves so that antifreeze can reachevery part of the plumbing system during the winterization process.

Once these steps are completed, you can safely disconnect allwaterlines and begin blowing out the rest of your RV’s water lines witha compressor.

By taking these precautions when disconnecting waterlines, you’llprevent costly repairs due to frozen pipes or residual water damage inthe future.

Connecting The Compressor

With water access successfully shut off, it’s time to gather suppliesand get ready for the next step.

As a seasoned RV maintenance technician, I always recommend choosingequipment that is specifically designed for this task. This includes anair compressor with enough pressure to clear out any remaining water inthe lines.

Before pressurizing the compressor, make sure all tanks are drainedcompletely. Any leftover water can cause damage when mixed withcompressed air.

Once everything is properly prepared, connect the compressor to theRV’s city water connection using a blowout plug or adapter. Double-checkall connections before beginning the process of blowing out the lines toensure safety and efficiency.

With all necessary steps complete, it’s finally time to begin blowingout the lines. While there isn’t necessarily a strict ‘step-by-step’guide to follow, there are some general guidelines that will help you doso effectively without causing damage to your RV’s plumbing system.

Blowing Out The Lines

Blowing Out the Lines

Before using a compressor to blow out your RV water lines, there areseveral steps that you need to take. The first step is securing fittingsand attachments properly so that they do not become loose during theprocess of blowing out the lines.

Next, drain all tanks from your RV including fresh water tanks, hotwater tank, and gray/black water tanks.

Once you have secured all fittings and drained your tanks thoroughly,it’s time to inspect all of your RV’s lines for any damage beforebeginning the winterizing process.

After inspection, set the pressure regulator on your compressor to30-40 PSI which is enough to force air through all pipes without causingany damage. To ensure that every line in your RV is blown clear ofwater, start at each tap one by one until no more water comes out.

After blowing out all of the lines in your RV with compressed air, besure to clean up afterwards.

Remove and disconnect any hoses or connections used in the processand store them safely away until next use. It’s also important todouble-check that everything has been put back where it belongs andsecure any tools or equipment used during maintenance tasks so theydon’t go missing later on.

By following these simple steps after winterizing systems properlyensures that your RV will stay safe throughout harsh weatherconditions!

Cleaning Up Afterwards

Now that you have successfully blown out the lines, it’s important totake a few additional steps to ensure your RV is properlywinterized.

First, prevent leaks by checking all faucets and connections fordamage or wear. Replace any faulty parts before storing your RV for thewinter.

Secondly, perform water heater maintenance by draining and flushingthe tank to remove sediment buildup. You can also use this time toinspect the anode rod and replace if necessary.

To further protect your RV from freezing temperatures, consideradding pipe insulation to exposed pipes in areas such as the underbellyof your RV. This will help keep them from freezing and potentiallybursting during cold weather.

Lastly, don’t forget to drain tanks completely before storage. Thisincludes both grey and black water tanks as well as fresh watertanks.

By following these winterizing techniques, you’ll be able to enjoyyour RV for years to come without worrying about costly repairs due tofrozen pipes or other issues caused by cold weather.

Conclusion

So, there you have it folks! You now know how to blow out an RV waterline with a compressor. It all starts with proper preparation andshutting off the water access to avoid any unwanted accidents.

As an experienced RV maintenance technician, I always recommend usinga high-quality air compressor with enough pressure to properly clean outthe lines. Connect this tool to your RV’s city water inlet and slowlywork your way through each faucet until clear water comes out ofthem.

Lastly, don’t forget about cleaning up afterwards! Properlydisconnecting and storing your equipment is essential for itslongevity.
