I've never had the need to winterize my '93 yet. But next year we're planning to leave it somewhere in the Pacific Northwest.
Looking at my plumbing I don't see anywhere to inject RV antifreeze. So I may have to install a 3-way valve. But, I'm a total newbie, so please tell me what is the proper way to winterize. I'm thinking to blow out the water with air (with all faucets open) then pump RV antifreeze until it flows out of each faucet. Or should I not blow out water and just pump antifreeze?
But, how do you get antifreeze through the hot water lines? Don't want to fill the water heater (plan to drain it).
