Water in basement

[jeremywatco]

So I took a boondocking trip a few weeks ago to our favorite beach campground. While preparing for the trip I had to make sure our fresh water tank was totally topped off.

Once I arrive I found that everything in the same basement compartment as the water tanks was a little damp. Not soaked, just damp. I poked around at the time and couldnt find any leaks and water tanks were full still.

When we got back I had to rush into work and one thing led to another and I forgot all about the dampness and the water leak.

Fast forward to yesterday, I open the basement to get something and it smells pretty musty and mildewy. Whats my best course of action? This basement has doors on both sides, should I open both up and put a fan in there?

I'm sick of dealing with the dealership so I'd rather not take it back in.

Some freshwater tanks have an overflow valve (pressure release) up on top of the tanks if the tank is in danger of overfilling. My Winnebago has a valve like this but the water is designed to leak out of the basement. If you have a indoor/outdoor carpet in your basement flooring just wash them as usual. If you have a wet vac use that also. To get wet and smell out leave all compartment doors open and use a fan!

If the water tanks are right above the bay that you noticed moisture I have 2 thoughts, both have happened to me. You might have to remove a panel to expose the tank.
1. The fitting that is drilled and glued into the tank for the supply line to connect to has a problem. We tried everything to correct it but to no avail and had to have a new tank and fitting installed. We believe the problem was caused by the tank shifting a bit and that caused the seal to leak.
2. The sensors that monitor the water fill level leak. All the sensors are drilled into the tank at different levels and the middle one started leaking. All I had to do was tighten the fitting and that secured the fitting.
Hope this helps and good luck. And I would check all fittings that connect the tanks together and any fittings that have water lines connected to them. All have the possibility of leaking.

Is it normal to have two fresh water tanks joined together by one of those ribbed fill style hoses? That scares me! Thats how mine is, and I know from experience that those ribbed hoses dont always last forever.

If I understand you correctly those hoses won't be subject to continual flexing, bending, twisting, etc. so I wouldn't worry about them.

Yep leave the doors open to get air flow going...no need for a fan unless you want to speed up the process. The mildew smell will stay and eventually go away, but you can help eliminate it by going over all the surfaces with a pine scented cleaner like Pinesol or Simple Green.

X2 on the fill valve leaking. May need to clean gunk out of it. Another possibility is if you overfilled the tank and water was forced out and leaked down into the basement.

My fill valve developed a leak. When I switched from fill to using the pump, the valve would still leak. I installed one of the garden hose brass shut off valves while I ordered a new fill valve from the manufacturer.
Check to see if you have water dripping out of the place where you hook up the hose to fill your tank.
