    Newbie Question - 2" hose for fresh water drain

    I store my trailer in a covered area but will need to take it to my house to flush the freshwater tank before trips. Instead of dumping antifreeze down the street when de-winterizing and/or dumping a bunch of water down the curb when santizing/flushing for freshwater, is there a hose that connects to the freshwater drain so I can divert to my property instead of the street. Neighbors can be picky.

    I tried searching for 2" fresh water drain hose but only found for smaller fittings not found on GD trailers.

    Thanks in advance.

    EDIT: OK, I know you don't put antifreeze in the freshwater tank.

    I'm not aware of a "fresh water drain hose." The outlet is smooth 2" PVC and there would be no way to attach a hose of any kind unless you glued some type of PVC fitting and/or step-down adapter to the outlet. Stepping it down to something smaller would dramatically increase the drain time, too.

    You could put a 2" to 3" PVC adapter on the output pipe then attach a RV sewer adapter to it. Using some RV sewer hose (preferably new and only used for this purpose) you would be able to route the fresh water drain to your desired location. Good way to water your lawn!

    Your antifreeze would go into you gray and black tanks. So you can leave it there until you hit a sani station or hookup site. You could empty them in a bucket and flush down your toilet at home or hookup to your septic system if you have one. It wouldnt be that much. As for the fresh, if you don't want to dump in your driveway, one could use a bucket, or one of those sani buggies, or you could use the exterior hose along with your fresh water pump.

    I adapted the fresh outlet to a garden hose male, 3/4" IIRC. It's kind slow but convenient. Hose runs to a tree in corner of my backyard.

    Neighbors would be picky about sanitizing the fresh tank? I could see the pink antifreeze getting the stinkeye from uniformed, but water with a very low concentration of bleach isn't going to harm things. Oh well, you can easily adapt to the drain. Easiest would be to use sump pump hose and threaded to barb adapter. They on the mouth of the valve, you will need the slip to threaded adapter.

    From another GD owner, I got the idea of putting a 2" rubber connection with a hose clamp. I then fitted a 2" PVC to 3/4" threaded connection so i can connect my garden hose. It will be slower but may keep the neighbors from complaining. I can then run the hose back onto my property and to the backyard.

    Thanks for everyone's input.

    This is the answer. You don't need to "dewinterize", it is done by simply flushing the lines until you have water and letting it collect in your grey and black tanks until you flush at the end of your first trip. Don't make it harder than it needs to be.
