Winterizing Questions

I have a 2016 Surveyor 32 BHDS.. the model is likely not important for this conversation but I thought I would give it anyway.

I am ready to winterize the trailer; however, I have conflicting information and I am trying to decide how to proceed. The manual for the 2015 year (2016 is not posted but they seem generic so not for sure it matters) says to dump RV antifreeze in the fresh tank and use the on-board water pump to circulate it to each faucet.

HOWEVER, the dealer told me when I did my walk through that I would need to access the pump (which is behind/under the bathroom sink vanity cabinet) and use the suction side 3-way valve and attached suction hose to pull antifreeze from the jug to circulate through the system. I found the pump and the valve and hose are already installed. It came that way from FR so I feel like FR planned for it to be done this way.

Question - If I use this suction hose on the pump what happens to the suction line coming from the fresh water tank. I did use the fresh water tank this year. I have drained it but can I assume the suction line from the tank to the pump drains back to the tank? That seems risky since the fresh tank is in the front of the trailer and the pump is mid-way back.... sure seems like a long run of suction hose to leave potential water sitting in.

I would like to avoid putting the antifreeze in the fresh tank because it will take a lot more effort to flush the tank out in the Spring. If I need too though to make sure I don't have a suction line to replace I will.

Once I figure this out the rest I have no issues completing.. ie draining HW tank, etc.

If you have an air compressor set it to about 40 psi and then blow air back through that line to the tank and also open up the valve at the bottom of the fresh water tank too allow the air to go straight through, you will have to disconnect the suction at that "3 way valve" to accomplish this..I'd say that valve is actually a 2 way valve as per say..in open its straight through from the tank and in bypass it's suction from your antifreeze bottle..make sense?

Yes that makes sense and you are correct.. its a two-way valve.. I misspoke. I did think about doing just what you said but of course the hose is crimped on the end of the valve so I can't just take the hose off. I could remove the crimp.. pull the hose off and then hose clamp it or put a new crimp ring on.. but wow what a pain.

If you do as you mentioned you will be good to go. Forget about the freshwater tank. Do not add antifreeze to it. Later RJD

When I do my winterizing I let the pump run with the fresh water tank empty. I found this got the water out of the line. I would open the low point drain and then run the pump for a few minutes.

Don't know how yours is set up, but on Berkshires there is a hose that attaches to a two way valve at the fresh water tank and pump. I turn the valve off to the fresh water tank which opens to the hose and then turning on the pump pulls the antifreeze from the jug and circulates it through the plumbing system. I then open each valve in the system until the pink stuff goes through. Make sure you turn the valve off to the water heater to bypass it and drain the hot water heater. Hope this helps. I've got to believe that most set ups are similar.

I think the OP is more concerned about what happens to any water sitting in the line between the freshwater tank and the pump. My setup is like yours...turn the valve and it pulls from the antifreeze jug. I have never concerned myself with any water sitting in the line from the fresh tank and the pump, and now this post has me concerned. I have never had a problem though, so I am thinking the line from the pump to the tank just drains itself back to the tank??? Unless the low point drain takes care of that?

Happy Vibe - I like this approach. If the pump will pull fluid out of a jug then it should pull any water out of the suction line if you let it run for a few seconds.... just have to be careful not to run it too long dry... I am sure the pump is not designed to run dry for very long.

I will think about this approach and see if I am comfortable with it. I don't like the idea of cutting the crimp ring off just to blow the line back to the tank.

WFD - the concerns you are having now is exactly why I posted. I am thinking though most RVs are setup this way so either the water in that line drains back to the tank or like Happy Vibe said if you run the pump for a little bit with the fresh tank empty it will pull any water out of that suction line and push it forward.

I have a 2016 Class-C by Coachmen. Our 2008 Freelander had what I thought was a great set-up from the factory with suction or fill tank or city water selected in a "water box) and three valve handles.
The 2016 now requires me to empty my basement storage and after climbing in I have to remove a wood panel that is 5' long then try amd move multiple electric cables to get to see the water pump.
The FR instructions wants me to disconnect the inlet side of the water pump and then make a suction line to suck antifreeze into some of the water lines.
I know I could install a special valve but I still am concerned about having many feet of water line that is not protected.
Here is what you system seems to be. Note I believe there is a check valve between the pump and the line that goes from the city water inlet to the various sinks etc.

My concern is that line A & B which are maybe 8' long will have no antifreeze protection. Also Line C at about 4' has no antifreeze protection. I really don't want to have to somehow get antifreeze into the Fresh Water tank. This isn't mentioned in the instructions from FR.
