Most of the time, inspecting a water line leak is entirely free of charge. A person can identify it by themselves if the leak is somewhere inside the garbage disposal unit or any other device. However, identifying leaks can become challenging if the leaks happen underground.
The only way homeowners can detect underground leaks is to get a higher monthly water and utility bill. Also, when there is a leak, the water meter will constantly blink a red light. Hence when this happens, it is prudent to call an expert plumber who can inspect the exact cause of the leak.
Apart from this, the cost of detecting the leak depends on a few circumstances, like the location and accessibility. However, the average cost to detect a water leak can range between $150 to $400.
