Another winterize ?

[2007dura]

I was putting on wheel covers today and noticed 2 low point drains directly behind the wheels on entry door side. They were full of pink stuff, but wondered if I needed to drain anyway? I drained fresh water tank, but hadn't noticed these 2 drains.

I also have 2 water lines in my vanity in bedroom besides the 2 to sink. I can't find a way to get pink stuff in them, but they look dry. Also have a 3rd line that runs near outside shower, same thing, no pink stuff but looks dry. Have I winterized wrong, or are these lines there for a purpose, but not hooked up?

I never winterize but I'm gonna take a shot at answering these questions.

These low point drains are for your hot and cold water lines and should be drained.

I also have 2 water lines in my vanity in bedroom besides the 2 to sink. I can't find a way to get pink stuff in them, but they look dry.
These are vent lines and yes they are dry.

Also have a 3rd line that runs near outside shower, same thing, no pink stuff but looks dry.
This is your black tank flush line and it also should be dry. You could put antifreeze in it but it would just gravity feed into your black tank.

I am sure someone will correct me but I think I got your questions answered.

Glen hit the nail on the head. The others are the black tank flush. If You open the other 2 lines "with pink stuff" in them some antifreeze will run out but it's no big deal. If the lines are filled with antifreeze then drained they will still be protected.

The rv antifreeze does not freeze solid and expand like water but it does turn slushy when it gets cold.

1. It's a good idea to drain the low point drains but since they already are full of antifreeze I probably would not drain them. If you do, you'll need to run antifreeze through the system again.

2. As Glenn said, those lines under the vanity are dry. They are black tank flush lines. No need to drain them or get antifreeze into them. At least I never did.

3. Glenn may be right but I suspect that single line under the coach near the outside shower may be the drain for the fresh water tank. It should be drained to make sure there's no significant amount of water in the fresh water tank. No need to put antifreeze in the fresh water tank although it doesn't hurt anything if you do.

As Glenn said, if I messed this up, someone jump in.

Steve, When 2002dura says "have a 3rd line that runs near outside shower" I am taking for granted the lines he is refering to are in the basement. On the 2955RL the lines for the outside shower and the flush line run side by side in the basement.
The freshwater tank is at the back of the 2955 and so is the freshwater tank low point drain.

As far as the 2 low point drains with pink stuff I would suggest draining them. As they were never drained before the antifreeze was added there was still water trapped in these lines. The antifreeze was probably diluted with this remaining water thus raising the freezing point of the antifreeze.

Glenn, you're likely right. I don't know anything about that model outside of the floorplan.

By the way, we're a 'go' on that thing I emailed you about.
