fresh water drain

We have a 2017 Bighorn 3160. The water tank drain had been working. Now when I open the drain nothing comes out. I ran a wire up it and the wire hits something solid. Any ideas? I know I can use my pump. Repair guy says would have to take bottom covering of 5th wheel off and possibly take tank down.

just up inside of colplast is a 90 degree. thats probily what the wire hit. you will have to drop the colplast to access the drain tubing. what ever side the drain is on you may be able to drop that side down far enough to get access. on our old bighorn 2017 you could on the off door side.

The fresh tank drain PEX tees into the tubing that runs between fresh tank and pump. So pushing a wire in would hit the top of that horizontal tubing run.

If you're not getting any water out, maybe the tank is empty.
