Changing fluid-filled tires - how to drain the stuff out?

[4570Man]

I don't think there is anything to patent It is just using the idea of having air in the tire to push the fluid out thru the small tubing..

Agreed, nothing to patent. I use the same method to drain water heaters to winterize the place. They would drain on their own, but it's a lot faster with air pressure. While that's draining I'll go open all of the valves 1 at a time. Since the lines are pressurized it'll blow most of the water out. Then I have a pressure tank with a water valve on it. Fill the tank with antifreezes and use a double female hose ( washing machine hose ) to hook that valve and another valve on the house together and blow antifreeze in the lines.

Looks like a liquid/air separator will be too expensive. I may try the $10 vacuum pump that hooks up to an air compressor. Otherwise it may be the $5 squeeze bulb with tubing. Still a pain.....

It doesn't have to be an elaborate separator. Something simple like this would work as long as you don't over fill the bucket. The biggest problem is something cheap like a 5 gallon bucket is likely to collapse under the vacuum pressure.

That may work. Won't be pulling much vacuum. Thanks for the tip.
