I would suggest buying some First Alert water alarms to place under toilets, in the water heater drain pan, and near the washer. They will sound an alarm if water gets on the floor. You can get a pack of three alarms for $30 on Amazon. Cheap insurance.

This won’t help OP much as there will be no one in the house to hear the alarm, he’s planing on going away.
There are a lot of smart system nowadays that bolt right on top of your main shutoff instead of the manual handle, they can automatically close the water main if they sense excessive flow or if one of the wireless water alarms go off. On most you can also remotely shut the valve right from your smartphone. And the once with flow sensor you can monitor any flow during your time away.
