Sewer backup: what to do first
Protect the house while the line is blocked
Raw sewage is a health hazard and a fast-moving flood. Treat any backup as wastewater, not clean water, and take these steps in order.
- Stop using water everywhere, including toilets, showers and the washing machine.
- If wastewater is on the floor, shut off power to that area only if you can reach the panel without standing in water.
- Take photos of the damage and the affected drain for your insurance claim.
- Call the 24/7 line and tell the dispatcher which drain is overflowing and whether it is a toilet or a floor drain.
Do not run a shop vacuum on sewage. It spreads contamination and ruins the motor.
Why main lines stop, and what a cleaning actually does
A main sewer line carries everything from the house to the municipal connection. Five things block it most often: roots entering a joint, grease collected over years, wipes sold as flushable, a pipe belly that holds water, and a broken section that collapses inward.
Cleaning clears the line with a drum machine or a jetter, fed through a cleanout outside the house or through a pulled toilet if there is no cleanout. A cutting head chops roots, a spinning chain scrubs the walls, and a jetter flushes what remains. A plumber who cleans the line without a camera pass leaves the cause unknown.
Signs the problem is the main line, not one fixture
- More than one drain is slow or backing up at the same time.
- A toilet flush makes a tub or floor drain bubble.
- Sewage rises in the lowest fixture when the washing machine empties.
- A sewage smell appears near the cleanout, the yard or a floor drain.
- The problem got worse during or after heavy rain.
The backwater valve rule in El Reno
El Reno's city code adopts the International Plumbing Code (IPC) with local amendments. One amendment requires a backwater valve on every building sewer that connects to the public sewer. The valve is a flap that lets wastewater flow out but closes if it tries to flow back in.
If your house has one, it needs occasional maintenance, because debris can hold the flap open or stick it closed. If it does not, and the house backs up when the city line is under heavy flow, a plumber can tell you whether adding a valve makes sense. Ask the El Reno Community Development office at 405-262-2000 about permit requirements for that work.
Main line backing up?
Call the 24/7 line. A licensed plumber can be scheduled the same day when one is free.
Common causes and what usually fixes them
| Cause | Clue | Usual fix |
|---|---|---|
| Roots in a joint | Backups return every few months | Cut the roots, jet, then repair or reline the joint if it keeps recurring |
| Grease buildup | Slow kitchen drain first, then the whole line | Hydro jetting, then change what goes down the sink |
| Wipes and paper | Sudden stop after a family gathering | Cable machine and removal of the plug |
| Pipe belly | Water sits in the line, repeat clogs at the same distance | Camera to confirm, then repair the low section |
| Collapsed pipe | Cable stops at the same spot every time | Sewer line repair after a camera pass |
What affects the cost of sewer line cleaning
Many homeowner policies exclude damage from sewer backup unless an endorsement is attached. Check yours so you know before the plumber leaves.
Sewer line cleaning questions
Yes. The line is open 24/7, including holidays. A licensed plumber is scheduled the same day when one is available. A sewage backup is treated as urgent, so say so when you call.
Most homes have a cleanout, a capped pipe outside near the foundation or the property line. If none exists, the plumber may pull a toilet or use a roof vent, and may recommend installing a cleanout so future visits are simpler.
No. A main line backup is too far from the drain opening for chemicals to help, and the caustic water becomes a hazard. Stop water use and wait for a plumber.
The line from your house to the connection with the city sewer is generally the property owner's responsibility. The city handles its own main. Call the City of El Reno at 405-262-4070 if you suspect the problem is in the public line.
Repeat clogs every few months, especially in an older house with mature trees, point toward roots. A camera shows them clearly, and the plumber can show you the footage.
No. If the line is cracked, collapsed or sagging, cleaning only clears the symptom. A camera pass tells you which it is, so you do not pay for repeat cleanings.
Next steps after a cleaning
If it keeps happening
Hydro jetting cleans the pipe wall, so a repeat clog is less likely.
If the pipe is damaged
Sewer line repair replaces a broken or sagging section, which a cleaning cannot fix.
