To be clear, the method I used to winterize my 318SAB was to put the pump intake hose into a gallon of antifreeze.
I would connect the outside shower hose to the Flush line and run antifreeze thru the shower and flush lines and into the black tank.
Then after I had winterized the entire system I would turn off the pump and bleed off most of the pressure in the lines, but leave just a little pressure. Only when the pressure was reduced would I activate the check valve manually to force antifreeze thru that line.
If you tried to activate the check valve at full pressure - first it would be hard to do, and you stand a good chance of ruining the check valve in the process.
Hope that helps.
