Check the Water Meter
With all water fixtures off, note the reading on your water meter, then check it again after two hours without using any water. If the reading changed, water is moving somewhere in the system even though nothing is turned on — a strong indication of a leak. This applies across the Phoenix-area neighborhoods we serve, not just one part of the city. You can learn more about our Phoenix water damage restoration company and how we help Phoenix homeowners recover quickly.
Inspect the Usual Suspects
Walk through and check under sinks, behind toilets, around the water heater, and near washing machine hoses for any dampness, discoloration, or mineral buildup. These fixtures and connections account for a large share of household leaks and are the easiest to catch early with a visual check. If you want to go deeper on this, our guide on What to Do in the First Hour After Water Damage in Phoenix covers it well. We also break this down further in Smart Water Sensors for Phoenix Homeowners: Are They Worth It?.
Watch for Indirect Signs
A water bill that's noticeably higher than usual, a musty smell in one part of the house, a warm spot on the floor near a hot water line, or a small area of grass that's greener than the rest of the yard can all point to a hidden leak even when there's no visible water. See our guide on signs of hidden water damage for a more complete list. For background from an independent source, see the IICRC S500 restoration standard. the Insurance Information Institute's claims overview has useful guidance on this if you want to read further.
When to Stop DIY and Call a Professional
If the water meter test shows movement but you can't find an obvious source after checking accessible areas, that's the point to bring in a leak detection specialist. Trying to track a hidden leak further on your own often means guessing where to cut into drywall or concrete — exactly the kind of unnecessary demolition professional detection tools are meant to avoid. You can also review FEMA's National Flood Insurance Program for an outside perspective on this.
