In the Town of Clifton, public sewer is available only to existing buildings that meet Fairfax County's guidelines, so many homes are not on municipal sewer. A plumber can still clear the drains and building line inside your property. Call the number on this page to be connected with a local plumber in Clifton.

Signs your drains need attention
- Several fixtures slow down at once, starting at the lowest level
- Toilets gurgle when a tub or washer drains
- Water stands in the shower or tub for minutes
- Sewage odor indoors or near the building line in the yard
- Soggy ground over the line between the house and the onsite system or street
A single slow drain is usually a local clog. When the whole house slows, the building drain is likely blocked, or, on a private onsite wastewater system, the system itself may need attention. Cut back on water use until a plumber has looked.
Local conditions in Clifton
Clifton is a tiny historic village in southwestern Fairfax County, a National Historic District since 1984, with wooded single-family lots and equestrian land to the north. Its median home dates to 1940, so cast iron and clay drain pipe, older joints and roots from mature trees are all common. The Town has no water system and homes rely on private wells. Public sewer is available only to existing buildings that meet Fairfax County's administrative guidelines and needs County approval to connect; new homes on vacant lots must have room for an onsite wastewater field.
For homes on Fairfax County sewer, the County's 24-hour backup line is 703-323-1211, and the owner maintains the private lateral. For homes on an onsite system, the plumber clears the drains and the line toward the tank; pumping or repairing the system is separate work.
What affects the cost
- Pipe age: old cast iron and clay may need cutting heads or careful jetting
- Distance: long runs on larger lots take more cable
- Roots: a common issue under Clifton's mature trees
- Camera work: useful to judge whether old pipe can be saved
- Timing: nights and weekends usually cost more
When you call
You are connected with an independent plumber who serves Clifton. Let the plumber know whether you are on County sewer or an onsite system, how old the house is and which drains are affected. Clearing a clog needs no permit. If a drain repair is needed, building permits come from Fairfax County Land Development Services, but the Town's Mayor or a designee signs the application first; for interior-only work, the Town clerk can provide a letter to the County.
