Winterizing your 320 TaB plumbing

About this time last year, I posted a tutorial on how to winterize our TaBs for the novice owner.  We just finished the task and I have updated the 2018 version.  It went much easier this year and I think I simplified the steps for ourselves and everyone:)  I will see if we can replace last year's version.  Hope this helps!

    Thanks for posting this. Clear & simple. It helps to have something like this to follow. I also put about a gallon of RV antifreeze into the fresh water tank. During our 1st winter in MN there must have been a little water at the bottom of the tank despite having been winterized at the factory. The nylon elbow behind the fresh water drain froze and cracked. In the spring the water tank gets rinsed and sterilized as a matter of course so it really isn’t any extra work.

    FYI, last year's version has already been replaced with this update.

    Thank you!  Newbie here and was a little anxious about getting it done correctly.

    Thanks for sharing (Sharoning?)...nice job.  Our first winter I did the pink stuff and it went OK; a little bit of a pain to drain the Alde then be sure it’s bypassed (and unbypassed next Spring).  Last 2 years I’ve blown the lines out with my small compressor...I just did it yesterday (freezing temps coming this weekend) and did it all in 20 minutes, including having to jockey the [email protected] to a level spot.  One small recommendation along those lines, I don’t strive for “level”, but slightly tilting to the left (portside) as all the lines and drains are left of center.

    Fresh water tank drains to starboard.  It went quickly for us this year, too.  @DurangoTaB, since you are now only blowing out the lines, do you bother with turning the Alde bypass valve at all?  We don’t.

    First time for me also as a new owner.  I just winterized mine this last weekend as well, hooked up the compressor and blew out all the lines.  Drained the fresh water tank, grey and black also fully, drained ALDE and bypassed it.  I put the antifreeze in the kitchen sink, shower drain and toilet and flushed a bit of it down also.  I quickly opened the grey and black gate valves and closed them to make sure the pink stuff got on them.  I also ran the 12v water pump dry for a min or two and emptied the filter basket of water.  The only thing I didn’t do was put the antifreeze in the fresh water tank.  What does everyone suggest on that?  I have heard it’s not necessary and some say it is.  I live in a colder climate in CT, I would appreciate any wisdom anyone can offer on this. I have a 2019 [email protected] 320S, thanks!  :)

    @dhauf, we are in Michigan. Plenty of snow, ice and ccccold. If you thoroughly blow the lines, even if there are a few ounces of water left in the tank, it freezes, expands with plenty of room in the tank, and does no harm. We leave the fresh tank valve open through the worst months and close it before critters become active as spring approaches. No pink stuff in the fresh tank for us. Have been through 2 Michigan winters, heading into the third and no freeze damage so far, but because of our proximity to the big lakes we can sometimes sneak in a camping weekend in December. Then again, it takes us longer to thaw in the spring.

    @dhauf, the purpose of bypassing the Alde is to be able to add antifreeze to the plumbing lines and avoid the hot water tank.  But, since you already bypassed it, you are in a perfect position for the springtime sanitizing with bleach - thus avoiding the Alde. Why didn’t I think of that!

    @Sharon_is_SAM...our 2014/15 FW tank drain is portside...changed with model years?  And we don’t open the Alde bypass, nor do we sanitize in the Spring (but maybe we should)...just flush the lines well.

    If portside is driver’s side, then that us the first I have heard of the tank draining on that side.

    IIRC somebody else with an older model (@jkjenn, maybe?) mentioned a driver's side FW drain.
    My 2015 (manufactured in Dec. 2014) has the drain on the passenger side under the step, so that suggests the change was made in the late 2014/early 2015 production runs.

    Ours is as @DurangoTaB's is. Front left corner FW drain valve. Note we only have the 5-6 gallon (interior) FW tank.

    Thanks @dragonsdofly and @Sharon_is_SAM appreciate the input, really did not want to put the pink stuff in the fresh water tank.  I will take @dragonsdofly suggestion of leaving the fresh water valve open on the holding tank during the winter months.  I appreciate everyones input on this.

    I've been working on this weatherization process for the first time.  We have a 2018 320 S Boondock with the newer 3020 ALDE heater.
    I just received the air compressor connection thingie (sorry, cannot recall the offical term) that screws into the city water connection, so I am now ready to actually do this.
    I've read though all the forum posts and the guides on this (at least all the ones that I've found here), and I'm pretty sure that I understand most of what I'm suppose to do . . . except for the ALDE part. I don't understand how to drain this into a 2.5 gallon bucket. When the hot and cold drain valves are open, where does this drain out?

    Under the driver side bench, look at the plumbing that goes through the floor of your TaB.  There is a Cold Water Drain Valve (on a blue pipe) and a Hot Water Drain Valve (on a red pipe).  They allow water to drain out of the corresponding TaB pipes and if you look underneath the TaB, you will see the drains protrude.  The Alde Hot Water Tank has it’s own valve that exits through the floor and also drains underneath the TaB.  There should be a flat, yellow, plastic tab resting on top of a blue pipe that also goes through the floor.  That yellow tab flips up and opens up the Alde Safety Pressure Relief Valve/Drain and the hot water tank then drains out underneath the TaB.  Place your bucket under the protruding drain.  All 3 of these drains are pretty close together.  To identify a drain, briefly open up the Cold Water Drain first and note which drain the water exits, then do the same with the hot water drain.  

    In the instructions I created, I noted that it was helpful to pressurize the plumbing system using the pump prior to emptying the Alde Hot Water Tank.  If you do this, you should get a more rapid emptying at least initially, then it will taper off.  Just be patient and let it drain.  Raising the tongue may speed things up, too.

    Sharon, Thank you so much for those excellent instructions!  I just got home after a late evening at work, so I'll have to wait until this week end, when I will be able to look at our [email protected] when it is daylight.  The weatherization process has been a bit overwhelming for me, as I've never done anything like this before.  But no, thanks to you, I'm pretty sure that I can handle it. 
    I live in the NH White Mountains, where it gets way below zero, so I really need to get this right.

    Once you do it, it makes sense.
