These quick connect air hose couplings are handy dandy connectors.
I had my plumber install one between the shut off valve and the outside faucets of my house, so I can connect my compressor to blow out the lines so I don't have a freezing issue. Like the pros blow out underground sprinkler systems.
I also cut the hose of my hand pump garden sprayer, and put a quick disconnect in it.
This way, I can connect the sprayer, (Filled with RV antifreeze) to the air purge connection to the outside faucets. Then I can pump the antifreeze into the line.
I calculated for a 40 foot run of half inch pipe, it would take about 52 ounces of fluid.
pi = 3.14
r squared = .25 x .25 inches
1 foot = 12 inches
3.14*.25*.25*12 = 2.355 cubic inches per foot of run
1 inch cubed = 0.554 liquid ounces
2.355 * 0.554 = 1.30 ounces per foot of run.
40 * 1.30 = 52 ounces.
