Only thing is to tighten fittings so they don’t come apart while using adapter.

Makes wintering a breeze

Installs easily and quickly, and works well. Remember to keep your air pressure under or around 30 psi to protect your pluming.

Completed winterizing RV without the hassle of putting antifreeze in water lines. Will not have to deal with cleaning antifreeze prior to next use and allows me to use RV during winter and immediately winterize. Put around 20lbs air pressure into the lines and opened all faucets to clear lines of most of the water preventing freeze damage. Highly recommended.

Winterizing the camper is typically a pain, so I wanted to condense the process. If you know what it is, it is pretty self-explanatory. If you dont dont what it is, you dont need one. The material is solid and durable. Good size. Works exactly as described. No complaints here. Used it for thr 5th wheel this winter and had no issues.

Totally an easy way to winterize the water lines in your camper. Its super small so it fits easily in the toolbox so you can lose it and but another next year. Deducted a star because the 3 pieces its made from arent Teflon taped together. Add your own. 1. Drain the lines out the bottom of your camper. 2. Drain the water heater by pulling the anode. Replace it when done. 3. Check that your air system is set to 40psi or less. Install this into the water inlet. 4. From there run each cold water faucet until it only flows air. Then do the hot water faucets. 5. Run the potty and the showerheads inside 6. Run outdoor shower. 7. Check them all again and then disconnect the fresh water inlet. 8. Open some faucets and then pull anode on HWH again. 9. Not a bad idea to blow out the black wash system if you have one. 10. Antifreeze in the sinks for pea traps, potty for the seal and bath tub. Add some to each gray tank and your black too. 11. Dont forget to drain the fresh water tank too.

Worked as it should. It’s great to not have to use a weird “drinking safe” antifreeze in the lines of the rv this year. Or vodka in the lines. I’m not fond of flushing the lines for a half hour at the start of camping season to get them “clean”.

This comes in two pieces. You really need to add your own thread tape and tighten up for a leak-free fit. Or dont it doesnt really matter that it leaks a bit at the connection, its just air after all. I like this method of winterizing my trailer much better than putting weird antifreeze in the same lines you bathe and drink from. Also cheaper than buying antifreeze and I assume better for the environment too.

Fair price easy to use.

Works great!
