How much air pressure should you use to winterize an RV?

Manuals recommended 40 psi max. Be sure to get the last drops out of the water pump and check the refrigerator solenoid for water depending on 3-way or residential option. I also put extra RV antifreeze into the P-traps to insure I had some lingering in the gray water tanks.

How much psi do I need to winterize my RV?

Is blowing out RV water lines vs antifreeze?

Is blowing out RV water lines enough?

My preferred way to winterize a travel trailer is by blowing out the lines with compressed air. Air pushed through pipes using an air compressor has the ability to push every drop of water out of the pipes, leaving them perfectly try before they have a chance to freeze. It’s clean and quick!

Will RV holding tanks freeze?

Having your holding tanks freeze can cause substantial damage that isn’t just a hassle to fix, it’s expensive too! The potential to freeze is largely dependent on your holding tank’s location within your rig. If they are above floor level, the ambient heat of your interior furnace will help to delay freezing.

How long does it have to be below freezing for RV pipes to freeze?

How long does it take for RV pipes to freeze? In general, the temperature has to dip below freezing (32 F) for approximately 24 hours for RV pipes to freeze.

Do you put RV antifreeze in the freshwater tank?

Do not pour antifreeze into your fresh water tank to run it through the pump into your water system. This will take a lot of antifreeze and is not very efficient. Even when the tank is drained there remains some water in the bottom of the tank which mixes with the antifreeze and lessens its protection level.

Is it safe to dump RV antifreeze on the ground?

Do I have to put antifreeze in my RV?

In most cases, 2 or 3 gallons is all you’ll need. You don’t need to fill your tanks with antifreeze. However, after you’ve emptied the tank, you should add a quart of RV antifreeze to the tanks to protect the seals and valves. What you need to do is remove the water from your plumbing so only antifreeze is left.

How do you drain RV lines?

Open the freshwater tank drain underneath the RV.

Turn it counterclockwise until fresh water begins flowing from it. Some RVs also have low drain point valves nearby. They will be close to the freshwater tank on the side or back end of the RV and labeled. Open them as well to help drain the lines.
