Common causes
Main line clog
Grease, wipes, and paper build up where all drains join.
Tree roots
Roots enter older clay or cast-iron sewer joints.
Pipe belly or break
Dallas clay soil movement can sag or crack the line.
City-side issue
Less common, but the city line can back up too.
What you can check yourself
- Stop using water immediately: no flushing, laundry, or showers.
- Note which fixtures are affected; tubs and showers often show it first.
- If you have an outdoor cleanout, see whether water is standing in it (do not open it if it is under pressure).
- Call Dallas 311 if neighbors report the same problem.
When to call a plumber
This is a call-now problem. Sewage backing into the home is a health hazard.
How a plumber diagnoses it
A plumber clears the main line from a cleanout and recommends a camera inspection to find the cause.
