Fairfax drains at a glance

The City of Fairfax is the historic county seat, with an Old Town core and surrounding neighborhoods whose median home dates to 1967. Houses that age often have cast iron stacks and older building sewers, where scale and shifted joints catch grease, paper and roots. The City's Department of Public Works handles wastewater inside city limits; unincorporated areas with Fairfax addresses are on Fairfax County sewer.

Clearing a clog is service work. If drain pipe has to be replaced inside the city, plumbing permit applications go to the City's Code Administration; in the County they go to Fairfax County Land Development Services. When you call, you are connected with an independent plumber who works in Fairfax. In older City homes, ask the plumber to note the condition of the cast iron near the cleanout while the line is open; heavy scale or thin spots there are a hint about the rest of the system and worth knowing before the next clog.

Drain Cleaning questions in Fairfax

Who handles sewage overflowing from a manhole in the street?

Inside the City of Fairfax, call City wastewater services at 703-385-7810, or 703-385-7924 after hours. For Fairfax-addressed homes in the County, call 703-323-1211.

Are older cast iron and clay drain lines harder to clean?

Usually, yes. With a median build year of 1967, many City of Fairfax homes have cast iron with heavy scale and older laterals that admit roots, so a cutting head or jetter is common.

Should the line be checked with a camera after a main line backup?

In an older Fairfax home, a camera look after a main line backup is worth it. It shows roots, offsets or broken pipe that a cable alone will not fix.

Why does a basement drain we rarely use smell like sewer gas?

The trap in a seldom-used basement drain can dry out and let sewer gas through. Pour a bucket of water in every few weeks.
