While replacing their water heater, the first-time homeowners found something unexpected behind a curtain in the laundry room. They discovered a loose wire that seemed to run from the washing machine outlet to a nearby pipe.
Here's what to know
While describing the situation on r/AskElectricians, the original poster said, "We are first time homeowners and our home was built in 1940," and explained that a laundry-room inspection behind a previous owner's curtain turned up an outlet with "this strange wire connected to it" beside washer connections that appeared "very worn."
Most replies interpreted the wire as an attempt to create a ground by attaching the outlet setup to plumbing. "Looks like somebody hooked up a makeshift ground," one commenter wrote. Another concurred, saying, "Looks like they used the pipe as a grounding point."
Rather than treating it as accidental damage, commenters said it looked like a deliberate, if imperfect, safety measure. One commenter explained, "This way if the hot hits the box it will ground out and trip," and added, "It is not ideal." Another commenter also suspected the three-prong washer plug might be connected through a two-prong adapter, pointing to a broader grounding issue common in older homes.
More background
The outlet came to light only because the homeowners were already in the middle of a water-heater replacement and decided to examine the utilities concealed in the laundry area.
They also said the washer supply connections appeared worn, were "not currently leaking," and were positioned close to the outlet, leaving older electrical equipment and aging plumbing crowded together in a room where water is regularly used.

Money was part of the discussion, too. One commenter warned that the ideal fix "could get expensive." At the same time, another commenter said, "Hell, you don't even need to replace the metal box," suggesting the eventual correction may be more limited than a full overhaul.
What can be done?
For the near term, commenters focused on reducing risk until a full repair is possible. "Until I could afford the ideal solution I would secure these wires," one commenter wrote.
They also said that if a temporary bond stays in place, it should use a sturdier conductor instead of a thin, loose wire hanging near the receptacle and washer hookups. That would still fall short of a proper repair, but it could make the installation less sloppy in the meantime.
Overall, the thread pointed to a properly grounded receptacle as the real solution rather than depending on a water pipe for grounding. Commenters said that if the washer is connected through a two-prong adapter, that needs to be fixed as part of addressing the outlet.
In older houses, routine projects can expose hidden fixes, especially in a laundry room where aging supply lines, a metal box, and an older circuit come together.
What first looked mysterious turned out to have a more specific explanation. As one commenter put it, "It is not ideal, but it was someone's way to make it safer."
