So here is one for you...
I left the Cameo today about 4 pm city water connected, 1/2 tank of fresh water and about 1/3 in the grey tank. DW and I returned 8 hrs later to a small puddle under the rig. I opened the service door to find the fresh water overflow outlet putting out water. I opened the fresh water fill cap and water gushed out until the pressure was released. I checked the tank levels and found the fresh water was completely full and the grey tank was 2/3 full. I drainD off 1/3 of the fresh tank and turned off the city water to be sure we didn't have further issues.
I also looked into the plumbing area to find water on the floor. It looked as though the water was dripping from the fresh water overflow line.
So how did all this happen? Is this some campground prank?
I cleaned the tanks earlierumm the day and used the black tank wash feature, but I am so confused.
Every time we leave the RV, we turn off the water at the city water connection. We also never leave the pump on. We have read too many instances of things happening when the water is left on. It is a thing to turn the water back on, but gives us peace of mind while we are away from the RV. I cannot imagine how you ended up with all the water in the tanks unless you had some sort of malfunction or a valve in the wrong position.

the anti back-flow feature on your pump may have failed .... if so, it allowed city water to flow from the water lines, back through the pump and into the fresh water tank ... as to how it got into the gray tank, the only thing I can think of is the water level in that tank may have been right on the edge of activating the second sensor .... if so, it would only take a little additional gray water added while you were testing to activate the light

My freshwater pump has an integrated check valve that can & has leaked. When we first got the trailer I noticed a slow drip from the open drain valve on the fresh water tank. There was some construction debris in the check valve & once flushed out, it was fine. This would be the first place I would look.
Some rigs have a "Fresh water fill" valve. This is used to fill the freshwater tank when hooked to city water. My valve is near the water pump. If left "ON", it could/would create the situation you described. Check to see if you have that valve.

The check valve in your fresh water pump is defective. The tank is just a coincidence.
A good habit to get into is shutting off the fresh water when the rig is being left for any period of time. My wife calls me paranoid but I've read too many "waterfall from the camper" stories for me to care about her teasing.

X3 We never leave the campsite for that long and leave the water on , we always turn the water off at the water supply and also turn off the water pump if we are dry camping as well as the water heater. check your check valve on your city supply. You may want to look into battery operated leak dectors I have them under each sink and at the water pump in case something leaks and we are around the trailer we will know before we damage the wood floor or carpet. You could also leave your fresh water tank drain open when connected to city water if you see it draining you know you have a problem, good luck and safe travels
