Forecasters warn of several inches of rain in western Washington from Nov. 10 to 12, and sewage typically surfaces in the lowest openings of a house first.
BREMERTON, WA, UNITED STATES, November 11, 2026 /EINPresswire.com/ — Sewage backups usually show up in a home’s lowest openings, not in the yard, and that is where a storm-week homeowner should look first.
Forecasters warned that an atmospheric river would reach western Washington and the Cascades from Tuesday through Thursday, Nov. 10 to 12, and that several inches of rain are possible in some areas, which could lead to flooding, according to the National Weather Service as reported by the Everett Post on Nov. 5.
Heavy rain can overload shared sewer lines. When the water has nowhere to go, it rises first through the floor drain, the basement toilet or the bathtub.
WHY IT MATTERS
Sewage is treated as contaminated water, not clean water, because it can carry bacteria, viruses and parasites. Porous materials such as carpet pad, insulation and drywall usually have to be removed rather than dried in place. Many standard homeowners policies exclude sewer and water backup unless an endorsement is added, so homeowners should ask their agent about it now.
The volume is large even at small depths. One inch of rain on 1,000 square feet is about 623 gallons, or roughly 2.6 tons (HelpMeNow calculation: 83.3 cubic feet of water at 8.34 pounds per gallon).
WHAT HOMEOWNERS CAN DO NOW
1. Keep fats and oils out of the kitchen drain and never flush wipes labeled flushable.
2. Ask a plumber whether the home has a backwater valve, a one-way flap in the sewer line that lets sewage leave the house but not enter it.
3. Find the outdoor cleanout, the capped pipe on the sewer line, before a backup starts.
4. Cover unused floor drains and keep a little water in each trap.
5. Photograph the water line, damaged items and drain before touching anything.
THE FIRST 10 MINUTES
Stop the flow by not running water, flushing or starting the washing machine. Keep children and pets out of the room, and if water reaches outlets or the electrical panel, stay out and call the utility to cut power to that area. Mold can begin growing within 24 to 48 hours in damp materials, so the drying clock starts at once.
