Antifreeze connection size four winds 24F

[Hickorybill]

Anyone know the connection size?

Looks like a half inch.

Also if I blow air through the Ciity water connection, can I avoid pumping anti freeze through the water lines?

Not sure what you’re asking about the antifreeze line. I think it may in fact be a half inch but it doesn’t “connect” to anything. You just stick it into a jug of pink RV antifreeze, turn the valve to “winterize” and let the pump push the stuff through each line and faucet. Don’t forget to bypass the water heater first.

Blowing out the lines as you suggest can work and it is one of the recommended ways to winterize. In my experience though you have to be pretty careful and run a LOT of air to be sure no water remains in the faucet assemblies. PEX water lines are somewhat freeze damage resistant but plastic faucets are doomed if there is any water lurking in them!

Some of the coaches do not have a flexible antifreeze line that you can stick into a jug. You have to make one yourself to connect to the "port" that Thor left for you.

The connection for "winterizing" aka pumping antifreeze thru the unit is 1/2 inch NPT, and is located behind a panel inside the long vertical door on the right, below the sink. There is also a shutoff valve and a male plug there as well. I got a a male fitting with a 1/2 inch tubing connector at our local hardware store. Just remove the plug, screw in the male fitting and tubing, shut off the valve to the fresh water tank, and start pumping.
