Why it comes up in the shower first

In a single-story Buena Park home on a concrete slab, every drain in the house connects to one main line that leaves the house and runs to the city sewer in the street. When that line is blocked, wastewater has nowhere to go and rises at the lowest opening, which is usually a shower, tub or floor drain.

That is why flushing a toilet or running the washer makes the problem worse. Each gallon you send down a drain ends up on the floor somewhere else.

What to do right now

  1. Stop all water use.No flushing, no showers, no dishwasher or washing machine. Tell everyone in the house.
  2. Close the main water shutoff if needed.If someone might forget, or an appliance could start on its own, closing the main stops new water from entering the drains.
  3. Find the cleanout if you can.Many homes have a sewer cleanout, a capped pipe outside near the foundation or in the front yard. Do not open it yourself if sewage is backed up; the pressure can push waste out. Just note where it is for the plumber.
  4. Protect belongings.Move items away from the affected room if you can do so without touching sewage.
  5. Call a licensed plumber and your insurer.Describe which drains backed up and what you were using at the time. Take photos.

Is it your line or the city's?

  • IfOnly your house is backing upThe blockage is most likely in your lateral, between the house and the street.
  • IfNeighbors on the same street are having the same problemContact the City of Buena Park, since the city sewer main may be involved.
  • IfYou are not sure where your responsibility endsAsk the city which part of the lateral is the property owner's to maintain.

After the line is cleared

  • Ask for a camera inspection so you know whether roots, a break or a belly caused the blockage.
  • Ask for a copy of the camera footage or still images.
  • Have the affected area cleaned and disinfected properly, or ask your insurer about sewage cleanup services.
  • Throw out porous items that soaked up sewage, such as rugs and padding.
  • Ask whether a backwater valve or a better cleanout would help your house.

Common questions

Can I use a chemical drain opener on a sewer backup?
No. Chemicals rarely clear a main line blockage and leave caustic water sitting in the pipe and on the floor, which is dangerous for you and for whoever clears the line.
How long until I can use the drains again?
Once a plumber has cleared the line and run water to confirm it flows. If the camera shows damage, they may advise light use until the repair is done.
Will it happen again?
If roots or a damaged pipe caused it, likely yes unless the underlying problem is fixed. That is why a camera inspection after clearing is worth asking for.
