Knucklehead Noob Mistake

I got a 2011 International Serenity FB 25' last summer in Arizona, drove it home to WV last fall. My wife got cancer in November, and I was so distracted that I don't think I did anything to winterize except drain the gray and black tanks.
It got below freezing maybe twice this winter, for about a day each time.

Problems so far.

- Toilet value popped at supply line hookup. Fixed.
- Water pump sprung a leak near the input side. New pump ordered.
- A 2" pex tub (hot water I think) in a rat's nest of tubes near the water pump drips pretty freely.
- When I fill fresh water tank, it only takes about 2 gallons. But status was 3/4 full. So I blew some air (former trombone player) into the fill tube, now status is full. Slow drip coming from belly pan.

> I can probably swap out the pex tubing.
> Does the belly pan hold up the water tank, or is the water tank separately attached? If I'm lying under the belly pan when I drop it, is a 300 pound water tank going to land on me?

> Where else might I expect to find problems from a lack of winterization?

My wife's plumbing is fine now, but the Airstream's is kinda screwed.

Sorry to hear of your troubles and your wife's health challenges. I can't imagine how challenging that would be. Best wishes for good health going forward.

The pan and tank sort of coexist together. The tank is strictly held by metal straps so you remove the pan, it drops a bit an reveals the straps you remove those screws and it all sort of drops out. The other tanks are a bit more challenging so I hope they are fine.

If the tanks did not have more than 50% water there is a good chance the tank is not actually damaged rather a tube that extends from it. So remove the little access plate and look at the drain and drain valve area first. Also the water could be coming from a leak in the outlet tubing above the tank. You may be able to see this from the space where the water pump is.

Edit: If you have an outside shower, that could be another problem area.

Thanks Brian. I think I'm going to install a new water pump, and replace the leaky pex piping, then turn on the pump and see what leaks.
