Winterizing Newb - Forgive and answer?

OK folks, I'm sorry for this post. I can't help it I'm an all out newb and a worrier, asking some silly questions.

2005 Fleetwood Pioneer 18T6

It's going to be stored in Niagara Falls, ON. It's going to see some fairly cold temps (well below 0c).

So. I've flushed and flushed the black tank to where it runs clean water (ew.), using the wand to wash down the sides of the black tank.

I Drained the grey and white tanks.

I drained the water tank and bypassed it with the valves.

I drained the low point connections.

I then flushed all of the lines with RV antifreeze. Starting at the toilet (furthest from supply), then shower head, shower faucet, lowpoint connections, sink faucet, outdoor shower (dealer installed option), kitchen sink and let a little burp out of the city inlet.

I ran lots of fluid into the traps to ensure they're full of antifreeze as well.

The hot water tank, do I just install the plug and call it good or do I add some antifreeze into the drain and then install the plug?

The system is still under pressure, do I leave it this way or do I allow the pressure to drain off - maybe even let it drain into my water tank?

Should I leave the antifreeze in the bowl of the toilet or let it drain into the black tank - should the black and gray tanks be drained of antifreeze too (I'm thinking no).

Is there something I missed?

Again, sorry to ramble on with these simple questions.

  • I am at elevation 3200 feet in the high country of NC and we have lots of sub zero weather.
    You are right on, except you should put a spoonful of pink stuff in the city water inlet to protect the check valve. ( I learned the hard way)
    We always leave what ever pink stuff gets into the holding tanks there after we pump it through the various pipes

    By the way you have a great trailer. We had the Pioneer 18T for quite a few years before going to a 25 foot Pioneer which we now have.

  • Thanks Everyone for the input! It is very much appreciated!

    To flush the system I bought a 3' length of reinforced hose from Lowes and hooked it up to the pump, simply hung the other side into the bottom of the antifreeze jug. 3 jugs of antifreeze and the hose = $16 total cost involved. Supporting the jug is KEY.:S

    I wondered about the Atwood water heater not having a rod in it, the manual for this model is... vague at best. Good to hear it's not meant to have one!

    The outside shower was forgotten all year long (filthy in there!), but did get a/f run through it.

    Also noted the propane alarm went off a few times during the process (located directly next to pump compartment).
  • Only thing you might have forgotten is an outside shower. Beyond this you have done everything needed.
  • I'm in a cold area (MN), and I've settled on leaving some antifreeze in the black and grey tanks. As others have indicated, make sure the pump has anti-freeze run through hit, and depressurize the system.

    Sounds like you'll be OK.
  • Make sure there is antifreeze in the pump too. There should be assuming that you drew the antifreeze into the system using the pump.

    Do you have an ice maker in the fridge? Or a separate water faucet at the sink for drinking water that has its own water filter? if so remove the filter and replace it in the spring. Blow out the lines.

    By the way, there are no stupid questions on this forum except the ones you should have asked but didn't. There are however, sometimes stupid answers. You'll have to sort those out yourself! :h
  • You're good to go, Atwood WH's don't have andode rods!

  • Thanks Newman,

    The hot water heater is drained and bypassed, there is a little pressure left in the lines from flushing the system with antifreeze.

    The hot water heater is an Atwood G6A-8E
  • if you drained and bypassed hot water heater there should not be any pressure on it just put the plyg back in it
    If it is a suburban hwh replace the anodw at this time.
  • As far as the antifreeze in the toilet goes, always have some kind of liquid in the toilet, whether it is water or antifreeze. That way the gasket won't dry out and crack. I leave about 3" of water in my bowl at all times - I don't have to winterize, but if I did, I'd leave a couple of inches of antifreeze in the toilet.
