Winterized the coach for the first time. Hopefully I did all water lines. First I drained the water heater, then blew out all the lines. Then moved the water heater bypass valve, then pumped the pink anti-freeze through the system and opened each faucet, ran the toilet, shower and outside sprayer then turned on the washer/dryer to fill a little and then spun it out to fill the drain. After that blew out the entire system again. After that poured some anti-freeze in each drain and the toilet. Now all the lines are clear and if there are any low spots that could accumulate liquid, it will be the anti-freeze. I blew out the water filter and ice machine lines separately, didn’t use any anti-freeze.

Should be good to go. We got below freezing last night.
