On the way home from dinner with friends tonight, I heard on the radio (KYW in Philadelphia) that an heating oil company accidentally delivered heating oil to a home that had converted from oil to gas heating. As a result, the oil flooded the basement of this home. The home's occupants were not there at the time. The news story said another company made the same mistake a few weeks ago.
This got me wondering about something. I might be wrong, but I seem to remember that when my parents converted their oil heating to gas, they had the plumber weld the gas pipe shut on the outside end so no one could take the cap off and make the same mistake. My parents were also concerned that pranksters could not pour anything down the pipe into the basement. This took the plumber only a few minutes to do and I assumed everyone who got rid of oil heating did the same thing, but apparently not. My parents' gas heater conversion was done by a close family friend so maybe their got special treatment, but I am curious why all people do not have the cap welded shut on their oil pipe or just remove the pipe entirely.
