sewage coming up through drains, tubs, or toilets is an emergency. It’s unsanitary, it gets worse fast, and every flush sends more water into the backup. Here’s exactly what to do — in order.
Step 1: Stop Using Water Immediately
Don’t flush, don’t run faucets, don’t start the dishwasher or laundry. Every gallon you send down goes straight into the backup. Tell everyone in the house: no water use until this is fixed.
Step 2: Keep People and Pets Away
Sewage carries bacteria and viruses. Keep kids and pets out of affected rooms. If you must walk through it, wear boots and gloves — and don’t track it through the house.
Step 3: Check Whether It’s Just Your Home
Ask a neighbor if their drains are acting up too. If multiple homes are affected, the blockage may be in the city main — call your water/sewer district first. If it’s just you, it’s your lateral line, and that’s on you to fix.
Step 4: Don’t Pour Chemicals Down the Drain
Drain cleaner won’t clear a sewer backup — it just sits in the standing sewage, creating a chemical hazard for whoever eventually opens the line. Skip it.
Step 5: Call for Emergency Service
A sewer backup needs a professional with a camera and the right clearing equipment — usually same-day. The camera inspection shows exactly where the blockage is: roots, grease, a collapsed section, or a belly in the line. Then you get options, not guesses.
What Causes Sewer Backups?
- Tree roots — the #1 cause in Southern California; roots hunt for moisture and crush into pipe joints.
- Grease buildup — poured-down-the-drain grease hardens into a concrete-like blockage.
- Collapsed or bellied pipe — old clay or Orangeburg pipe fails with age and soil movement.
- Flushed wipes — “flushable” wipes don’t break down. They’re a leading cause of residential backups.
