How can you winterize a travel trailer without antifreeze? The simplest answer is to blow out your water pipes thoroughly using an air compressor. This ensures there’s no water left in your travel trailer’s plumbing.
If you don’t have even one drop of water in your pipes, then nothing can freeze and burst your plumbing.
Follow our step by step guide below to learn how to winterize a travel trailer without antifreeze.
What Tools Will You Need?
For the most part, travel trailers and other RVs aren’t all that hard to maintain during the winter months. You’ll only need a few regular tools to winterize your travel trailer. It’s advisable to have a few other larger tools on hand to make winterization easier.
Tools You’ll Need
Standard Tool Kit
A standard set of common household or automobile tools can be purchased nearly anywhere. The toolset will include items like a socket set, screwdrivers and a standard sized wrench set.
NOTE: this is the most important tool you will need. You won’t be able to thoroughly rid your pipes of all water without one of these.
If you don’t own an air compressor, you can just rent a small one (at least 50 PSI) at any large local hardware store.
Often called a blowout plug, it connects to the air compressor. The adapter will then plug into the trailer’s water lines so you can blow out any liquids.They also come in various sets called RV Winterization Kits.
You’ll need this to flush out your waste tanks and connected plumbing lines, pipes and hoses.
NOTE: The hose will be connected to your WASTE TANKS. Please make sure the hose is dedicated ONLY for the purpose of cleaning out your waste tanks.
Do NOT attempt to use or connect the hose from your fresh water tanks to your waste tanks. This can lead to cross contamination and lead to all sorts of bacterial and health problems.
How To Winterize Without Using Antifreeze?
Dump That Waste Right Outta Your Tank
- The first thing you want to do is dump out and clean your waste tanks. It’s recommended that you head off to a local RV dump station for this.
- Once there it’s pretty simple to connect your tanks to the dump stations connectors. Everything will be well marked.
- Once connected, you’ll be starting with the black tank first, since this is connected to your toilet. Open the black tank petcock drain valve and drain your tank.
- Next, do the same for the gray water tank. We drain this after the black tank because the gray tank holds soapy water from your kitchen sink, shower, etc. Soapy water should take care of any remaining waste.
- TIP: Save yourself a huge amount of time (and disgust) by purchasing some chemical treatment for your black water tank. It’ll break down any nasty bits, make flushing out your tank a breeze and leave it smelling fresh.
- Flush the tanks with your dedicated hose.
- Lastly drain and clean the freshwater tanks.
Pump Some Fresh (Compressed) Air in There
- The next step is to set up your compressor and attach the blowout adapter to it. Then you’ll be connecting the blowout adapter to your trailer’s water inlet.
- Leave all water valves open to include sink, shower, etc.
- Set your air compressor to a range of 30-50 psi. Do NOT go above this range, as it might blow out your water system seals and cause lots of trouble.
- Use the compressor in 30 second increments until no more water comes out. Close all valves. It’s a good idea to put a bit of plumber’s teflon tape around the petcock valves to keep a good seal.
