Most expensive water damage is not dramatic - it is a $6 supply line dripping for three months. Once a month, spend fifteen minutes: look under every sink, behind the toilets, at the water heater base, and at the washer hoses. Feel for dampness; look for mineral crust and rust blooms that mark slow weeps.
In Georgetown, the hidden leaks checklist questions are read against a local fact first: Georgetown sits in Williamson County where the North and South Forks of the San Gabriel River meet, with Blue Hole, the swimming hole on the South Fork, as its emblem of the river that organizes the town. That fact is what changes the order of the steps below for a Georgetown household: what gets documented first, what can wait a day, and which call is the first call. The sequence itself is the standing one for this work; the local detail is what makes it this city's version of it.
Meter trick: note your water meter reading last thing at night with everything off, then check it first thing in the morning. A changed reading with no use means water is going somewhere it should not.
Replace rubber washer hoses on a schedule, not after a failure - braided stainless lines are cheap insurance. And know where your main shutoff is before you need it at 3 a.m.; finding it is a daylight job.
