Actually, we think we are now complete and confident we got our 25FB ready for freezing weather while it sits in storage this winter. After our fourth effort.
- Our trailer has not been used yet. All the water that has been thru it was done by the dealer when they were delivery checking it.
- We drained everything we could read about and think of. We did not blow any of the lines out.
- For some reason, I initially thought draining was all that would be necessary but my (much) better half persistently read the owner's manual, determining there needed to be more protection.
- I can't quite recall but believe it was a 15/16" wrench (or was it 1"?) to remove the plastic nut/plug from the water heater via the outside access door.
- Now is your chance to shut off the inlet valve (that AS likes to call the "bypass") on the side of the water heater so you don't run any more water or antifreeze in the water heater.
- I dutifully poured RV antifreeze down the drains.
- I finally became convinced we needed to run antifreeze in the lines and pumps so set out to do that.
- The manual seems to insist that I needed to remove the water filter under the galley. After looking/feeling at least three times and after calling my salesperson for advice, I was finally able to determine that the filter had never been installed.
- Unlike me, be sure to close your low point drains on the underside of the trailer before running (okay, wasting) your first gallon of antifreeze.
- You can also waste more antifreeze by dutifully removing the outside shower head and inadvertently turning on one or both of the ultra-easy turning handles as you stuff the uncapped hose back in the storage door.
- It took me a half hour to determine how to find the hose access to the water pump which is behind the furnace ducting hose under the refrigerator and not accessible through the access under the wardrobe as the manual seems to indicate.
- Have a flashlight with you.
- We used a plastic bowl to pour the antifreeze in and stick the now-disconnected hose in. You can't stick the hose down into the gallon of AF because the hose end is too large to fit. Now you can run the pump, utilizing your partner to turn on (and off) each water device rotating the hot and cold positions until you see the oh-so-satisfying pink AF running out.
- I wasted quite a bit of AF with all my inadvertent open drains and faucets during my multiple efforts to complete the task so recommend saving one trip back to the store and buy (at least) two gallons when you start.
- When I stopped in to buy my fourth (!) gallon of antifreeze, I also purchased a 20" length of water supply hose and a male/male connector so I can simply stick it in the gallon container next time I want to run more on the ground.
Enjoy not making the same mistakes I did!
