winterizing with compressed air
I have a 2004 Fleetwood Bounder which I have always winterized with anti-freeze in the lines. Last fall I was talked into having it done with compressed air and yesterday, when I hooked up the water ...

THere is no Venturi effect or any other effect with anti freeze. Just put it in.It's foolproof
You quite correct, as Mr. Bernoulli proved the drop in pressure that creates the Venturi effect requires, and is in relation to, an increase in velocity caused by restricting the flow.
Since the little 12 volt water pump has very little flow, and with a tap open VERY little pressure compared to a good supply of air being released into the system at ~50 psi there is almost no Venturi effect at all.
The result?
That water left in the dead end of the T shaped pipe has very little chance of being vacuumed out and replaced, or even mixed with, that pink stuff.
There’s an old saying about ‘fool-proof’ ......
Just when you think it’s fool-proof, along comes a better fool.......
