I was called out to a local hospital to inspect and locate some probable defects in the main trunkline, which originated in the boiler/mechanical plant, then through the kitchen and cafeteria, followed branches to four wards, then out to the street. Using the 4550 locator and the color mini w/in-line transmitter, I couldn't get a strong enough signal to locate the sonde. When pulled out of the pipe and tested above ground, the signal peaked. I had to tape a flushable 512Hz transmitter around the spring and run them both to get a locatable signal. I had my local Rigid Rep. meet me on the job. He told me that it was the tempature of the hot water flowing in the line that caused the problem. Is this so?
