Winterization

[Locknut]

I am winterizing my Vegas 25.3 for the first time and have a question.

I cannot find a low point drain other than the one for the fresh water holding tank. In all the other RVs that I've owned, there was also a low point drain for the rest of the water system.

I've done the following:

1. Drained the waste water tanks
2. Bypassed and drained the water heater
3. Used compressed air to flush the fresh water lines and the outside shower
4. Added RV antifreeze to all the sewer traps and tanks

I've looked at the Thor website, the Thor owner's manual, and in Ed's manual, and I can not find any information on a low point drain other than the one for the fresh water holding tank. I've searched in every outside compartment and no luck.

First...is there a Valve? And second, where the heck is it?

In the 24.1 there is only one drain line and valve right next to the fresh water tank. The only other way to drain the system is to turn on the outside shower or drain into the waste tanks and then drain them. The plumbing system was pretty simple when they started with the 24.1 and there was no real need for an additional drain point. With the numerous models now available, that may no longer be the case,

Even with opening all the valves and blowing out the lines, I still hear a gurgle in the shower pipes, like there may be water in a low point that is allowing the air through, but the water itself is not being pushed through. I guess I am just being paranoid, but I'd hate to fix frozen pipes in about 60 days. And I am reluctant to pump antifreeze into the water pipes...I know a lot of people do, but I've never liked doing that.

If all you are hearing is a little gurgling I wouldn't worry. If the water was to freeze it has room to expand and won't cause a problem. Temps have to be very low and stay that way for a while before any residual water to freeze, daytime sun helps keep just enough warmth unless it's really cold.

Our 24.1 has low-point drains for both the hot and cold water lines right behind the pump/tank area. Unfortunately I don't have a good pic of it.

Locknut: I'd suggest you ask Thor for the fresh water diagram for your coach. It will detail where all the valves are.

Here is the best pic I have of it:

My two low point drains are off the pic below the bottom. The one valve you see is the tank drain, and the half of the valve you see at the bottom is the feed turnoff from the tank to the pump (which is turned off when pumping antifreeze through the water system).
