Winterizing 28RL

My 28RL has a winterizing station in the storage compartment. I know about the water heater bypass. However, I am not sure about the other switch. Do I switch to winterizing mode and stick the short hose in a jug of RV antifreeze ....then use the pump to fill the system? How many gallons of antifreeze?

If by 'switch' you mean valve, then yes you will put it to winterizing mode and suck the antifreeze from the bottle. Saves you from having to put it in the fresh water tank for the pump to be able to push the antifreeze through the system. You don't want to put antifreeze in the fresh tank... it takes forever to flush out in the spring.

As to how many gallons you'll need.... depends on how much plumbing you have (every rig is somewhat different) and whether you blow out the lines first with air. It will take less when blowing out with air because most all of the water will be evacuated from the lines and so when the pink stuff starts coming out, it will not be diluted.

Usually 2-4 gallons is sufficient.
