Oakton is unincorporated Fairfax County, so most commercial properties are on Fairfax Water and Fairfax County sewer, though some addresses near Vienna are on the Town of Vienna's system. Fairfax County Land Development Services handles permits, including for like-for-like gas appliance replacements. Call the number on this page to be connected with a local plumber in Oakton.
How the call works
Describe the building, the problem and how much it's disrupting the business. You'll be connected with an independent local plumber who handles commercial work in Oakton, such as offices along Route 123, schools like Flint Hill, and retail near I-66. Ask what the first visit includes and how the work will be priced before it starts, and mention if you need it done before opening or after hours.
What affects cost
- The number of restrooms, kitchens or fixtures involved
- Permits for water heater and gas appliance replacements
- Backflow repair parts and the required retest
- Locating hidden leaks under slabs or in walls
- Scheduling around classes, office hours or customers
Oakton's utilities and rules
Fairfax County lists Fairfax Water for its residents, with water drawn from the Occoquan Reservoir and the Potomac River. The Town of Vienna's system, though, serves about a third of its customers outside town limits, so some Oakton addresses close to Vienna are Vienna water customers (703-255-6385) and may be on Vienna sewer. The water bill settles it. Fairfax Water uses chloramine most of the year and free chlorine roughly April through June, and its water runs moderately hard to hard, near 7.5 grains per gallon on average from its Potomac plant.
Fairfax Water owns the meter and its setting; every pipe on the property, including the service line from the street meter or valve to the building's main shutoff, belongs to the owner. The Fairfax Water Cross-Connection Control and Backflow Prevention Program, run with Fairfax County Land Development Services, calls for irrigation backflow assemblies to be tested at installation, every year, and whenever they're repaired or replaced. The program's line is 571-722-7653.
Permits go through PLUS. The County requires a Household Appliance permit to replace a gas water heater or furnace even with the same model, and a Residential Plumbing permit when new gas piping is added. Washington Gas serves most of the county; for a gas smell, leave the building first, then call 911 and 844-WASHGAS (844-927-4427), option 1. Sewer backups that might involve the County main go to 703-323-1211.
