When Should You Call an Emergency Plumber?
Sewage entering a basement, a burst pipe, uncontrolled water, or moisture around electrical or heating equipment may be urgent. Public manhole overflow or a suspected city-main problem should be reported through the appropriate municipal channel rather than treated only as private plumbing.
What Should You Do Before Plumbing Help Arrives?
Stop water use if it increases a backup, avoid direct contact with sewage, and close a safe shutoff for a supply leak. Do not enter a flooded basement with energized equipment. Note exterior cleanout and manhole conditions without opening or entering them.
