In McLean, a burst pipe or a backed-up drain means closing the main water valve first, and any gas smell means everyone goes outside before calling 911 and Washington Gas. Then call the number on this page to be connected with a local plumber in McLean.

The local setup
McLean is an unincorporated part of Fairfax County, about 9 miles from downtown Washington between the Capital Beltway, Georgetown Pike and the George Washington Memorial Parkway. Fairfax Water supplies the water and has an after-hours emergency line at 703-698-5613. Fairfax County's Wastewater Management program owns the public sewer and takes backup and overflow calls at any hour at 703-323-1211; the owner maintains the private lateral from the house to the county main. Washington Gas provides natural gas.
Neighborhoods such as Langley, Lewinsville and West McLean mix older ramblers with large rebuilt houses. The median house here was built in 1976, and many larger homes have more than one water heater, long supply runs and finished lower levels. That raises the stakes when a fitting fails at night.
Whose problem is it?
| Situation | Who to call |
|---|---|
| Water flowing in the street or from a hydrant | Fairfax Water, 703-698-5613 after hours |
| Sewage backing up with no fixtures running | Fairfax County, 703-323-1211, then a plumber if the main is clear |
| Burst pipe or failed water heater inside | A plumber, once the main is off |
| Gas odor | Leave, then 911 and Washington Gas |
| Irrigation backflow device leaking | A plumber or a county-authorized tester |
Warning signs
- Water running down a basement wall or through a ceiling light
- Gurgling toilets and a sewage smell from a lower-level drain
- Rust-colored water or a puddle under a water heater
- The water meter moving while every fixture is off
For gas, Washington Gas's leak line is 844-WASHGAS (844-927-4427), option 1. Call it and 911 from outside the house, never from inside.
Timing and paperwork
January cold snaps are the classic time for pipes in exterior walls, garages and outdoor spigots to freeze and split, and summer downpours test sump pits and basement drains. Fairfax County requires a permit even for a direct water heater replacement, so an emergency swap carries a permit step. Lawn irrigation systems need a testable backflow assembly that a county-authorized tester checks every year, worth scheduling once the urgent repair is done. After-hours rates usually run higher, and no arrival time is promised.
