How Much Air Pressure To Blow Out Rv Water Lines -

If you own an RV, it’s crucial to properly winterize your vehicle to prevent damage to your water lines
during the colder months. One of the most important steps in this process is blowing out your RV water lines
using air pressure. In this article, we will discuss how much air pressure you should use to ensure the
water lines are fully cleared without causing any damage.

Determining the Right Air Pressure

When it comes to blowing out your RV water lines, it’s vital to find the right air pressure to avoid
potential damage. Using too much pressure can lead to bursting the pipes, while too little pressure won’t
effectively clear out the lines. The standard recommendation for blowing out RV water lines is around 30 PSI
(pounds per square inch).

However, it’s important to note that the ideal air pressure can vary depending on factors such as the length
and complexity of your RV’s plumbing system, as well as the manufacturer’s recommendations. Therefore, it’s
best to consult your RV’s owner’s manual or contact the manufacturer for more specific information regarding
the recommended air pressure for your particular model.

The Blowing Out Process

Before blowing out your RV water lines, ensure that all faucets, showerheads, and other water outlets in your
RV are turned off and closed. Here’s a step-by-step guide to properly blowing out your RV water lines:

Connect an air compressor to the city water inlet of your RV using a pressure regulator.
Gradually increase the air pressure to 30 PSI or the recommended pressure specified in your RV’s owner’s
manual.

Start by opening the furthest faucet from the city water inlet, and then move systematically through each
faucet, including both hot and cold faucets.
Flush the toilet several times to ensure that the water line is fully cleared.
Continue this process until no more water comes out of the faucets or toilet.

Once the blowing out process is complete, disconnect the air compressor and close all faucets and water
outlets.

By following these steps, you can effectively blow out your RV water lines and minimize the risk of damage
during winter storage.

Additional Tips

While knowing the right air pressure is crucial, there are a few more tips to keep in mind when blowing out RV
water lines:

Frequently Asked Questions Of How Much Air Pressure To Blow Out Rv Water Lines

How Much Air Pressure Should I Use To Blow Out Rv Water Lines?

To blow out RV water lines, you should use around 30-50 psi of air pressure. Too much pressure could damage the lines, while too little may not clear out the water properly.

What Happens If I Use Too Much Air Pressure To Blow Out Rv Water Lines?

Using too much air pressure can cause damage to the RV water lines, such as bursting or cracking. It is important to follow the recommended pressure range to prevent any costly repairs.

Can I Use An Air Compressor To Blow Out My Rv Water Lines?

Yes, an air compressor can be used to blow out RV water lines. Just ensure you regulate the air pressure to the recommended range and use the proper attachments to connect the compressor to the water lines.

How Do I Know If I’ve Successfully Blown Out My Rv Water Lines?

To check if you have successfully blown out your RV water lines, open all the faucets and valves inside the RV, and then use air pressure to blow out the lines. If no water comes out, it means the lines are clear.

Is Blowing Out Rv Water Lines The Only Method To Winterize An Rv?

Blowing out RV water lines is one of the methods to winterize an RV, but not the only one. Other methods like using antifreeze or a combination of both can also be used depending on the RV’s plumbing system and manufacturer recommendations.

Conclusion

Blowing out your RV water lines is an essential step in winterizing your vehicle. Finding the right air
pressure is crucial to prevent damage while effectively clearing out the lines. Remember to consult your RV’s
owner’s manual or contact the manufacturer for specific air pressure recommendations. By following the
recommended steps and tips outlined in this article, you can ensure that your RV is properly winterized and
ready for the colder months.
