We're in Illinois and not leaving for warmer weather until January, so I winterized our coach this weekend so we don't have to keep it open and heated for 6 more weeks.
It was a bit aggravating - the manual is PAINFULLY generic, showing nothing specific to the 377 RLBH as far as where the drains are and left out some key pieces. The method walked through in the manual didn't work (opening ALL drains and faucets at once), and it took me hours of in and out, back and forth to (hopefully) get all the water out.
Here's what I did - any feedback would be great, especially if I missed something:
- I opened the underbelly drains that I could see, which I believe are the fresh water tank and refrigerator.
- My tanks were already empty, but I opened the two grey water & black water valves to let out the remaining water that came out with the blow out.
- I let the last bit of water out of the water dispenser in the refer(residential), removed the water filter from the refrigerator, emptied the ice bin, shut the ice maker off.
- I removed the drain plug on the hot water heater and let it drain and replaced the plug.
- I removed the whole system filter and put the housing back on.
- I opened all faucets.
- Ran the pump for 20-30 seconds
- Set on City Water, I used a blowout adapter with an air compressor, opened all faucets and away we go...very little actually happened, even with the compressor at 40PSI.
- I thought the Low Point sticker by the basement was perhaps for overflow at first but decided to remove the panel and found the two drain lines and opened those. Some water came out, but still not much.
- I then started closing faucets and drains until it was only one open at a time and started to see some progress...some real water was finally coming out, so I then kept alternating between the shower, stool, vanity, kitchen sink, outside shower, and low point drain lines, opening them one at a time and closing the previous one so all air was being directed to one faucet at a time. I did this for at least an hour or more.
Spurts of water came out every time. I just kept alternating, moving from one to the next until finally the last couple rounds produced nothing but a drop or two.
- I then removed the hot water heater drain just to make sure water didn't somehow get back in the tank.
- Closed tank valves, turned off the refer, pulled the slides in and left. It's still plugged in to keep the battery charged but heat is off now.
I saw on another thread about additional valves being located under the stove and under the island, but I didn't see either on mine.
I would think there is a much easier/faster way to do this - perhaps a specific order of faucets to prevent water from going into other lines that were previously clear?
I don't know. It just took so long and I just found it to be a bit aggravating and with such poor instructions in the manual I'm very much hoping I did it correctly.
Any feedback? Did I miss something?
