Were you on city water? [not positive about "water/hydro site"]
We always try to turn the hose bib off before retiring for the night, and use the fresh water tank for toilet water during the night. Noisier yes, but it prevents things like this, as one hears the pump come on when it shouldn't. Also prevents major problems on the rare occasion that a plumbing fitting lets go in the middle of the night. Also endeavor to turn off city water when leaving the trailer empty.
Glad the damage was limited!

As we started to wake in the morning my wife said" do you hear water dripping ?" I jumped out of bed to see the shower base full and just started running over base. Ran outside and drained off a bit of the gray water . Lucky we were just a bit nose high as the W/R is in the back so the little bit of overflow was contained .
I guess life is full of learning... Thought I would share this . We had a great trip overall !
