Winterized RV question.
« on: February 18, 2018, 06:22:38 AM »
Hi folks.  Ok so we bought a new 5th wheel last fall and when the season was over I winterized the rig.  No I'm not a complete newbie as we shared a Class A with my in-laws for years.  BUT as I was thinking about spring coming and getting ready for our first outing I couldn't remember if I actually drained the shower when I did all the rest.  I drained the fresh water, water heater and both facets in kitchen and bath but I think I forgot the shower plumbing.  My question is should I be worried about the lines getting frozen over the winter?  For sure a rookie mistake.

If you have Pex water pipe, you may be all right.  The fittings might crack before the pipe will. 
You did drain the gray water tank? 

Did you by chance leave the faucets open  if so the water would have not had anything to expand against and not caused a problem.

If you have some decent weather, why not water up the unit and check for leaks?

Used anti-freeze.  But like I said forgot to open shower head and run anti-freeze thru it.

Just wondering - if you raised the shower head with the pump turned off, and opened the spigots on the shower, would the water in the hose drain back into the fresh water tank?  Or is it better to pump antifreeze through the shower head ?
How about an outside shower?
just curious...

You should have pumped the pink antifreeze through the shower and also through the toilet.
 In other words through the entire system including all faucets.

No it would not because the pump has a built in check valve which would prevent this.

Thanks all for the responses.  I ran pink thru everything except the stupid shower head.  So that's the only plumbing I was concerned about.  Look's like we'll see in a few weeks now that the weather is changing.  Just wondering if anyone else may have a similar experience and what was the result?

If you have a conventional tub/shower faucet with the knob on the spigot you have to lift to get water through the shower, you might be ok.  Mostly when you turn off the water, that knob falls and the water drains back out of the hose, not into the tank, but down the drain.

On mine, the hose droops down then back up similar to a trap in a sink. That would be the only concern. Where the hose is open on both sides of the loop, it may allow for expansion when the water freezes. If that's all that breaks because of freezing, you're lucky. You can replace the flex hose.

Thanks Rene.  I think you're right.  The only water that might be trapped would have been in the hose itself.  I drained all tanks and ran water pump until air was being spurted out and then ran with anti freeze until it came out of taps.  So water in shower plumbing should have drained back down I hope.

It  is easy to remove the flex hose from the spigot assembly, which I do when winterizing. Hopefully you added some anti freeze to your black and gray tanks. I may get some disagreement here, but I feel that although you drained the tanks, there is still residual water in them that can drain down over time. It would puddle up against the closed valves and if a sufficient quantity, freeze and possibly cause damage to the valve area. May be overkill, but I add a good dose of AF to the tanks, "just in case". I also blow the  water lines out with compressed air and add AF, esp., in all of the "P" traps. Antifreeze is cheap compared to the trouble and expense of repairing cracked pipes.

It's way cheaper to just leave the gate valves open. ;D ;D ;D

Just as a point of reference, the cost to completely re-plumb a '00 Bounder 36S with PEX runs just about $9333.17.

Many just blow out with air, but one must be very diligent to get all the water out. Don't forget the little things, outside shower that you don't use, ice maker line if you have one, etc. With antifreeze, you still have to remember these things. The antifreeze just needs to be flushed out with a lot of water. A lot of folks sanitize their system right after the flush.

And so much depends on your rig, too. If you have a hydronic heating system such as Aqua Hot or Oasis, then you need the pink stuff, at least on the hot water side. The manual says that internally, it's so intricate that air cannot possibly get all the water out, and it doesn't take much to leave you with several thousand dollars in repair/replacement. On both my Beaver and my Ventana I've blown it out with air, then run pink stuff through the hot water side. So far so good...

Depends on how well you blow.
Winter 1: I used Pink Stuff. Spring 2 (got the RV Spring 1) I had a lot of "Fun" getting rid of all the pink stuff.

Winter 2 I blew the lines.. and blew, and blew and blew

Basically I opened all valves and blew till I ran out of air (Six gallon compressor 150 PSI max with a 50 PSI regulator) Then let it refil and blew again about 5-10 times till I no longer got any water coming out. Used pink in toilets and traps (Drains) where flushing it out is... Not required.

SPring 1 I had to re-assemble one fitting

Never again have I had to do that.

When doing this, I always open one faucet at a time and not all of them at the same time. Is that what you meant John?  I didn't want any newbie to get confused.

   Kemo,  Living in an area with temperatures similar to yours....I probably “overkill” a little bit. I blow it with air, but don’t spend a lot of time doing so. THEN...flush with the antifreeze. My thought....eliminate most of the water, minimizing dilution of the antifreeze. Once you get a good flow of antifreeze... you’ve taken care of the traps. I run antifreeze thru everything, shower hose, toilet (including the spray nozzle), and each and every faucet. “If” you have a washing machine....be sure to flush some antifreeze thru pump to displace any water. I’d rather spend a little more time “flushing-out” the antifreeze, than repairing damage!  Hopefully this will continue to work for us... it was -21 F yesterday morning. But today, the big inning of a heat wave....only a -18 F.

Wally,   That is an astounding number as PEX very cheap to buy the pipe and fittings themselves probably less than $100 for the whole coach.  I have plumbed 3 new houses for less than $200 each and that was running separate lines for each fixture.  It is super easy to run during new construction.   Through the bowels of a MH would be much more complicated, but not $9K more complicated. ;D ;D

My tongue in cheek comment was just that, as I live in very rural and dumping a little water on my lawn does not do as much as the grass roots reaching down to the septic fields in the yard.  Remember Erma Bombeck's book "The Grass is always greener over the septic tank" 8) 8)

Many thanks to all for your responses.  Exactly what I was looking for. Last question I hope...IF I have a leak in the shower plumbing how do I access it to fix it?  Or is this a dealership issue?

Here is another one of the "need more info" questions (no offense meant). But where is it leaking? And when? Behind the wall, from underneath the shower stall? When you run water? When a faucet is turned on?  More details may help you get a better answer.

It does not have a leak...that I know of.  As I have said all the pumbing was winterized with the exception (I think) of the shower.  I can't remember if I ran anti-freeze thru it when I did the rest.  Looks like an early spring so I'll get the chance to test it soon.  Fingers crossed.

     I’m not familiar with the construction of your unit. It may be an easy access or a real “bugger”. And, could be dependent upon how good you are at “do it yourself “ repairs.

     On my unit, everything is reasonably accessible... if you are a 130 pound contortionist. 😉

I posted this before but here is my opinion.

AIR is the way to go.  Anti-freeze they say won't hurt you - remember when they thought SMOKING was OK?
The point is it might take 40 years before the effects show up in large enough numbers to say it's RV related -
are you willing to take that chance?  I'll pass.

Lot's of people think the anti-freeze method is fine and maybe there right - but I doubt that the AIR method will be bad for you
in comparison.

But since you asked - that's my 2 cents worth of advice and what I plan on doing if I need to Winterize.

It's a good thing you don't have Aqua Hot or equivalent then. Air won't do the job on the hot water side for those. Expensive.....
