I came back to my trailer to find my shower and bathroom sink overflowing with water. There were no valves on the kitchen sink the bathroom sink or the shower. The water was connected to the trailer and pressurized. How is it possible for my Gray tank to have filled up without water going in ithe great tank directly from Either sink or the shower being turned on?

Hi and welcome, it would help to know what trailer you are in and water system you have. KantLeak (which can) or the Nautilus water control board ?
This is a tough lesson to learn about turning off pressurized water sources when you leave for a long period of time.

What is the water pressure at the site and do you have a regulator?

I have no idea how this could happen without leaving a faucet on. My recommendation to start looking for the source of the problem would be to put water in your holding tank, not hook up city water and run off your on board water pump. If there is a water leak the pump will run all the time. If the system holds pressure and the pump shuts off you need to look for another source of the problem.

Yes, excellent advice. This is something I have always been paranoid about

X3 - I need to get better at doing this myself.

I have the grand design 349M with a nautilus system.
This may have been a tough lesson to learn but I was gone for about 45 minutes. I don’t understand how my freshwater with the Fed directly into my gray water tank without any sinks for showers turn on

I do have a regular year

As soon as I return to the trailer and found the problem we turn the water off and dump the gray tank cleaned up the mess. And then proceeded to try to duplicate the problem and have been unable to. I’m stumped

[Dfanelli]

Yes I probably should shut off my water more often however this wasn’t a water leak. This was where my freshwater fed directly into my gray water tank while I was gone. I don’t understand how this happened
