Find it first. Then fix only what's broken.
A hidden leak is the only plumbing problem that gaslights you. The water bill jumps and you blame the landscaping. A warm spot shows up on the floor and you blame the weather. A faint mustiness comes and goes and you blame the dog. Meanwhile, somewhere you can't see, under the slab, inside a wall, water is running nonstop and keeping its own schedule. The bill is usually the first honest witness. If it climbed and your habits didn't change, something changed anyway.
Here's the part that should lower your blood pressure. Finding a leak is not the guessing game it used to be. Detection equipment listens through slabs, reads temperature through walls, and traces lines without opening anything, and the whole point of the visit is to mark the exact spot before a single thing gets touched. No exploratory holes, no tearing into drywall on a hunch. Find first, then decide. That's the order, always.
Sometimes, the equipment finds nothing. It happens, and it's genuinely one of the better outcomes, because now the biggest fear is crossed off the list and the bill mystery gets chased somewhere cheaper. Either way you stop wondering, and wondering is the worst part of a hidden leak. One call starts the search. What happens after it gets decided by you, with the facts on the table.
"You called, a person answered, and the problem got handled. That should be normal. With us, it is."
