Could it really be this easy?

I just winterized my 2005 HR Admiral and it seemed ridiculously easy. My last MH took much longer. I am afraid that i might have missed something. Take a look at what I did and let me know if I missed anything.

Drained all holding tanks. Black, Grey and potable.

Drained the hot water tank.

Drained the 3 water lines in the wet bay area.

Put 5 gallons of RV anti freeze into the potable water tank via the ez poor filler on the side of the RV.

changed the hot water tank by-pass valve to by-bass the tank.

turned the pump on.

ran water (first hot then cold) through the faucets (kitchen, bathroom, outside shower) until pink was flowing freely. Ran the toilet until pink was flowing freely.

poured anti-freeze into each drain.

reopened the 3 wet bay drains until pink flowed freely.



The entire project took about 20 minutes and was super easy. Did I miss something? How could it have been that easy? My last MH was so much more a pain in the butt.

    Or live full-time !!!What is winterizing:h
  • Assuming you have no ice maker or clothes washer, you're set. It's not rocket surgery. (Also don't forget about the outside shower if you have one.)
  • Not sure what is in your wet bay but I would make sure the city water connection has antifreeze in it. To do this, make sure the pump is off. Open a tap in the bathroom, then push in the little button in the middle of the city water hook up connection. The reason you do not want the pump on, is because if there is a lot of pressure in the line, when you push the button in, the antifreeze will displace an o ring in the connection. (Ask me how I know) If there is only a little or no pressure, the o ring will remain in place.

    Also make sure you have anti freeze in your exterior shower/water hose.
  • Do you have a clothes washer? Ice maker? Black tank flush?
  • You did it OK. Just make sure next spring you rinse your fresh water tank good to get all the pink out of it. Your water will continue to be foamy from the faucets until it's all cleared out, even though it may look clear in a glass after filling. When the foam finally is gone with the faucet is open, it's all good then.

    It is even easier if you blow the lines out with compressed air. (Cheaper too) but yes. it's that easy.

    Many people pay upwards of 100 dollars for that service.

    I put 2 gallons of anti freeze in the blank tank. And you are right, things would dry out.
