Fire Protection Leak detection at Sharonville Hotel

We were called out to perform a leak detection service on a fire protection line at rear of hotel near parking/landscaped island. The line was 4″PVC plastic feeding a fire hydrant which was within ten feet of the leak. I started at the hydrant and worked back towards the leak. The pressure at the hotel is fairly low, which made listening more challenging. There was a substantial wet spot where it appeared that someone had already begun to dig. The leak was actually right at that point, which is usually not the case. The client was pleased to have the leak solved so that they could get it repaired.
