In the City of Falls Church, a toilet that runs, leaks or clogs usually needs a tank part, a new wax seal or a cleared trap, and in the city's older homes the flange and shutoff often need work too. Call the number on this page to be connected with a local plumber in Falls Church.

Falls Church is a small independent city just inside the Beltway, and its typical home was built in 1971, with about half built before then. Fairfax Water supplies the city; it bought the former City water utility in 2014. The City's Department of Public Works runs the sewer system, and part of the city's wastewater is treated at Arlington County's plant while the rest flows through Fairfax County to the Alexandria plant. The Falls Church mailing area also spreads into Fairfax and Arlington counties, where those counties provide sewer and permits. In the city's older houses, the toilet may be newer than the flange, bolts and shutoff it connects to, so a repair often includes those parts.
What to do now
- Stop the water. Close the valve behind the toilet. If the valve is old and stiff, close the main instead.
- Don't flush again. Let the bowl level settle first.
- Protect the floor and ceiling. Towels at the base, and check the room below an upstairs bath.
- Try a sink. If the toilet gurgles or the bowl rises, the clog is beyond the toilet.
- Check the basement. Water at a floor drain points to the main line or lateral, which the owner is responsible for.
- Ask about sewer backflow protection. If sewage has backed up before, the City's Backflow Prevention Program reimburses homeowners for a sewer backflow prevention device installed by a plumber under a permit.
