You’re sitting at home and suddenly notice a strange sound—running water. But when you check the sinks, toilets, and appliances… you realized that everything’s off.
So what’s going on?
Hearing running water with no visible source is one of the most common signs of a hidden leak. Here’s how to troubleshoot it—and when to call an expert.
🔍 Step 1: Check for Obvious Causes
Start by eliminating the basics:
- Toilets: Lift the tank lids and listen for a hiss or refill sound. Silent leaks are often caused by a worn flapper or faulty fill valve.
- Irrigation systems: Make sure sprinklers or drip systems aren’t running (especially if set on a timer).
- Appliances: Check dishwashers, washing machines, and water softeners for leaks, drips, or odd sounds.
📉 Step 2: Turn Off the Main Water Supply
Here’s a quick test:
- Turn off your main water valve.
- Wait a few minutes and listen.
- If the sound stops, you’re dealing with a pressurized plumbing leak.
- If the sound continues, the problem might be external (irrigation, well system, or sewer line).
🧪 Step 3: Check the Water Meter
Use your meter to confirm a hidden leak:
- Turn off all water-using devices.
- Locate your water meter and note the reading.
- Wait 30–60 minutes (no water usage).
- Check the meter again.
If the numbers change, you’ve got a leak somewhere on your property.
