* Client had us out for plumbing inspection today. * Client wished for us to just flush the water heater, he didn't want us to inspect anything and the utility room. I noticed the gas line was a mixture of galvanized and black iron. This is highly dangerous. * Galvanized is not meant for pressurized gas. It is meant for water and drain line. * Client was unaware of this situation. I immediately brought it up to him once I noticed it was galvanized. * Client wishes for us to send over an estimate to properly install it with black iron.
