Winterizing Cougar 26SAB Problem

I also have the 26sab, Where is the check valve you refer to located?

Not sure about your exact situation, but I use this antifreeze pump for both the city water connection and black tank flush.

When using on the city water connection, I have the water pump turned off and a faucet open in the bathroom.

1) How do you make sure the street line from the hatch connection w/check valve to the connection to the main plumbing system gets antifreeze? I have the Polar Pack and can not see where that connection exists.
2) How do you winterize the No Fuss Flush line without using air blowout?

I may be a little dense, but what the heck is "the street line from the hatch connection w/check valve"??

I believe he means the "city connection" ???

Edited-

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.
