Paint stripping without a D/A

Iv actually considering this is it possible to hook two let's say 20 gallon ones together without back feeding into the other one?

I guess you could with some sort of check valve set up.
I haven't found the need for that.
I have the regulators at about the same setting and they come on when needed just by putting a tee between them feeding the line I'm using.
One hand helps the other.
I like it because it gives me a back up.
I don't want to start a project (like painting) and have an equipment failure.
20 gallon tank.
If you do it, you want a "dual voltage" motor so you can move the wires on it to 220 and not 115.
This cuts the current draw in half.
And get a cast iron pump.
I had one on a OLD "Sear" branded unit that lasted me for over 30 years of heavy use.
The two I have now are both branded "Cambell Hausfield".
One I bought at a store (grey) some years ago.
And the other is a blue one I got "new" on Craigslist from a guy.
The good thing in this set up is portable too.
If you got one big stationary unit it can be in the way sometimes.
