Water tank overflow?

[wayne Dwyer]

Just bought a 2019 Nitro XLR, started to fill the water tank but can’t find an overflow, how do you know when it’s full?
I don’t want to burst the tank and I never trust the level meters, any help would be appreciated.

Should look something like this.

When you see it pouring out from underneath TT.....it's full. Nowadays a lot of the overflow vents are just a tube on a fitting on the side of the tank and it points down from bottom of trailer.

Some water tanks will expand and burst with too much water. Measure the flow of your hose with a bucket and then time how long you have the water on. I don't usually fill the tank on shorter trips.

I have nothing out of the bottom other than the Hot and Cold low point drains, I have burst a tank in the past and I don't want to do it again

The overflow tubes will usually be right at the tank...

Not in the filler tube, which is the fill vent to allow air out of the tank while it is filling up.

Lots of trailers now have a little plastic elbow pointing down on each side of the trailer...usually somewhere near the axle(s).
