Scamp 13' w/o bathroom winterization

[RogueIT]

We have a new 13’ Scamp w/o a bathroom, and have only had water in the lines from the city water hooks ups. We are looking to winterize but as we have never used the fresh water tank, we are wondering what we should be doing to clear out the lines. Trying to avoid using the RV antifreeze, but don’t know what we need to do to winterize the city water lines and the sink to gray tank exhaust.

Thanks,
Scott

I am looking for a boler or scamp in Montana. Hope to find a 13ft

Scott, if all you have is a city water line to the sink, and a single faucet, I believe all you would need to do to drain that line would be to remove the hose, open the faucet and leave it open. Go outside to the port where your hose screws on and examine it. Remove the gasket and inlet screen, and you'll see a pin in the center. Move aside and push the pin in. A small amount of water may shoot out under pressure. Hold it open until fully drained.

If you look in your kitchen cabinet below your sink, you'll see a clear vinyl tube connecting your sink drain to your gray water tank. It will have water sitting in the lowest part of the line. If you can see the entire line; just push up the sag in the line, and let it drain into the gray water tank. If I was you, I would buy a gallon of RV antifreeze and pour some (a quart?) down the sink drain just to be sure. It is cheap insurance and won't hurt a thing. Finally drain the gray water tank.

I would make absolutely sure the fresh water tank has no water in it or the feed line to the sink. You said "new", Scamp, so I'm assuming the tank was never filled? Scamp uses air pressure to test the plumbing system, so you would know if the tank was ever filled.

Hopefully if someone thinks of anything I missed, they'll weigh in.
