I was called to a home to perform a WH flush and radon test. The client had noticed a musty smell in the house and wanted to ensure that there were no issues with the plumbing or radon levels. I used a specialized tool to flush the WH system and collect samples for testing. The radon levels were within the recommended range, but I recommended installing a radon mitigation system to further reduce the risk of radon exposure. The client was grateful for the thoroughness of the inspection and the peace of mind it provided.
