Best Swimming Pool Leak Detection in Columbus OH

My condo had a rare leakage, without any physical sign of water damages inside and out of my condo. City water shut my water off due to the low pressure of my water service line. With about 200 foot long water line and don't know where is the leak makes me very frustrated, and the cost to replace the whole line is over $10000.
Called 4 companies for checking the leak, American Leak Detection is super professional and responsive. They detected the leak within 30 min and it was underneath my bathroom of the condo unit. ALD is also giving me the best bid for repair. I was warned by other companies that replacing the underground water service line could potential damage the sewer system, and only ALD explained in details about how they would approach and make me less worried. Finally ALD replaced the water service line underneath my condo unit without any damages. Hooray!
Special thanks to the field expert for detection and supervision the repair. I truly appreciate your professionality!
