Fresh water overflow?
Hi everyone, I’ve got I think a 48 gallon fresh tank, but it’s not a gravity fill. My question is, Does it have an overflow valve somewhere? I’d hate to find out the hard way that it doesn’t. I know...

Thank you everyone. I was just leary of overfill after hearing stories of damaging RV’s. Now I know and I found them dangling by my drain plug as stated above. Also it makes sense that the displaced air needs to go somewhere, just never thought of it. Prefer gravity fill but we’re learning.
One modification for you to consider. If you travel with a full water tank, you'll likely find that you will arrive at your destination about 2/3 full as the water tends to siphon out the overflow while travelling. Many install a ball valve on the overflow(s) that remain closed ONLY while travelling so that you dont lose water. Just have to make sure they remain open all the rest of the time so that you dont blow the tank up, or collapse it with vacuum.
I did this on my Cardinal, as I always travel to my local camping destinations that are not full hookup with a full tank. I despise sitting at the dump station filling at arrival.
