Hotop Winterize Blowout Connecting Winterizing Review

This device blows the water out of your motorhome. The valve is very convenient as it gives you complete control over how much air you use at the rate you want. This offers much more control than a Schrader valved device, and the quick connect simply attaches to the air line.

For the past several years I have used RV antifreeze to winterize my RV. This year I tried to blast the lines with this device. I could only do one line/faucet at a time. I quickly lost pressure in the tank. If you plan to use this make sure you have a LARGE tank as air pressure will drop quickly. This is cheaper than using antifreeze.

It's easy and helped clean out the fresh water lines in my caravan - much quicker and easier than pumping antifreeze into the system and then rinsing the spring stock was on Plumbing adapter end about 1/2" longer to connect and control the valve as the RV connector is recessed into the wall compartment - a little awkward to attach.

This simple garden hose adapter will winterize my RV without antifreeze and save water without having to flush the lines after using antifreeze. I set the outlet pressure on my air compressor to 40psi; then I screw this adapter into the water pipe; then I connect an air hose and slowly open the valve to allow the compressed air to push all the water out of the pipes; Open all faucets and drains at low point and cycle back and forth with the appropriate water valves to drain all relevant lines.

As the cold weather approached, I needed to unclog my RV's water lines to keep them from freezing and damaging my plumbing. to drain my lines (open drains at low point, open faucets, water pump on, etc.). went home and did it again. By hooking this up to my air compressor, I was able to drain a few more gallons of water from my lines - I was in shock. Worth the price to save on expensive repairs! You have to tighten the parts (easy to do) and I can add some teflon tape for a better airtight…

First I drained all the fresh water from my tank. I set the air compressor to 30psi, closed the valve on this unit, connected it to the city water line, opened the fresh water drain valve and SLIGHTLY opened the valve on this unit and waited. As soon as the water was being forced out by the air, I carefully opened the valve even further. When it stopped I closed the air valve and the fresh water drain valve. Then I opened all the pipes (sink, kitchen sink), slowly opening the air valve until…
