We had the same thing happen - came home from a 2-week trip and heard what sounded like a shower running in our foyer - which is atypical

.
It turned out a pipe in our steam shower upstairs burst, and water was pouring through the ceiling. Very little water was on the floor considering how fast it was flowing, so it must have just happen minutes before we got home. Felt very fortunate also, despite the hassle of getting everything fixed. Can’t imagine what it would be like if it was pouring for 2 weeks.
Since then, we shut off the main water valve any time we are gone for more than a day. Bringing this back to refrigerators, we found out it’s important to shut off the ice maker when we cut the water, otherwise our GE refrigerator ice maker leaks water constantly. Shut off the ice maker switch for half a day, then It stops. Probably unique to our GE.
