I make a habit of just turning off the water to the whole house if I'm going to be gone for a few days. The shut off is right next to the washing machine. Not only does that give me peace of mind but its a good idea to work those shut off valves periodically anyway.
:thumbsup: I lived in a house once that was on city water. One day a washing machine hose burst when I was at home. I saw the water flooding the utility room and kitchen not very many minutes after it happened, but by the time I closed the valve that was feeding the hose, there was at least 1/2" or more water in the utility room, kitchen, and dining room. It happens !
I built the house that I now live in and it has 8" of cellulose insulation between the floor joists. If the house flooded, I think what a horror of a situation it would be to have to remove all that insulation, replace all the lower area of drywall on all walls,etc.,etc,etc., not to mention the probability of extensive mold.
So my preventative insurance is the following (and it takes only a few seconds):
The waterline from my submersible well pump comes underground via a pitless adapter to my water room/pantry where the pressure tank and water softener are located. Just downstream of the pressure tank is a brass ball valve that shuts water off to the entire house including the water softener.
I also power the pump (120V) through a dedicated outlet in the wall.
This is to protect the pump from transients and lightning damage during storms by simply unplugging it, thus completely isolating power, neutral & ground to the pump.
So, to protect the house from potential water damage due to such possibilities as a failed pex connection, a hose rupture on water heater, toilet, sinks, dishwasher, shower, etc., we (wife and I) simply shut the ball valve and unplug the pump whenever we both are not home.
Additionally, for peace of mind, I also close the ball valve just before we go to bed in case something failed during the night.
Once you do it a few times, remembering is not a problem; it just becomes part of your routine and takes all of 5 seconds.
Not high tech by any means, but completely effective and costs $0.
