De-winterize 22c

Hi
Just bought a used 2018. It was winterized at the shop. What do I need to do to de-winterize. Something to do with a cartridge and so forth. Manual is not very clear.

Thanks

Welcome to the JOF! Somewhere inside a cabinet, or behind a removable panel, there'll be a "whole house" water filter. It may be already bypassed when it was winterized, or they just removed the filter cartridge. Find it in your coach and see what they did, so when you hook up a water hose to the outside to flush out the antifreeze from the system, that filter canister gets flushed out completely as well, if it's full of pink stuff.

Make sure all the low point drains are closed. With water hooked up to it, open all the faucets, the shower, flush the toilet, and the outside shower too. When the water runs clear, it's de-winterized. After you do that, you'll have to switch the water heater bypass valves so it will fill with water. Hopefully it was bypassed so there's no antifreeze in it. That would require draining and rinsing out if it wasn't.

You may want to sanitize the plumbing with a bleach solution. That should be covered in your manual.

Welcome - absolutely NOTHING to add to what JFlight posted. Do exactly that - then come back with more questions!


It's a little unnerving the first time, but rest assured its not difficult! There are usually just a few small things you'll have to get used to. For me, it was finding all of the low-point drains.


You can't hurt anything. Go for it!
