Leak Detection in Silver Spring, MD
Quick answer: Turn off every faucet and appliance, then check your water meter. If the dial or low-flow indicator still moves, you have a leak. Running toilets are the most common cause of a sudden jump in your WSSC Water bill. Put a few drops of food coloring in the tank. If color shows up in the bowl without flushing, the flapper is leaking.
DIY leak checks
- Meter test: no water use for 30 minutes, then compare meter readings.
- Toilet dye test as above.
- Look for stains on ceilings under bathrooms and around the water heater base and the washer box.
When to call for professional leak detection
- Meter moves but you can't find water, which points to a leak in the service line or under the slab.
- Warm spots on the floor (hot-water line under slab).
- Persistent musty smell or a bubbling wall.
