Hydro jetting cleans a Great Falls building drain or sewer line by scouring it with pressurized water, removing grease, debris and roots. Because many homes here are not on municipal sewer, the plumber will want to know where your line goes before choosing how to clean it. Call the number on this page to be connected with a local plumber in Great Falls.

What happens when you call
The number on this page connects you with an independent plumber who works in Great Falls. The first questions are about your setup: is the house on Fairfax County public sewer or a private onsite wastewater system, and is the water from a well or Fairfax Water? Then come the usual ones: which drains are slow, how long it's been building and where the cleanout is. On site, the plumber locates the blockage, often with a camera, and decides whether a cable, a jetter or both make sense.
Cost factors
- Access to the line and how far it runs on a large lot
- Whether the line goes to a public sewer or an onsite system
- Roots, grease or debris
- Camera inspection and line locating
- Off-hours scheduling
Great Falls conditions
Great Falls is a largely residential community on the Potomac with big lots, and about a fifth of it is still rural. Many homes here rely on private wells, and many are not on public sewer, using private onsite wastewater systems that need routine pumping and inspection. Some neighborhoods are on Fairfax Water and Fairfax County sewer. The median home was built around 1985.
That split matters for jetting. On a public sewer, the plumber cleans the lateral toward the County main; Fairfax County runs the main and the owner maintains the lateral, and the County's 24-hour line for backups is 703-323-1211. On an onsite system, the plumber can clean the building drain and the line toward the tank, but a jetter sends water downstream, so the volume used and the timing relative to your next pumping are worth discussing. If the tank or field itself is the problem, cleaning the house drain won't fix it. Jetters also draw a fair amount of water; on a private well, tell the plumber so the supply isn't run low. Gas or plumbing repairs go through Fairfax County Land Development Services.
Checklist before the plumber arrives
- Know whether you're on public sewer or an onsite system
- Find the date of the last tank pumping, if it applies
- Stop running water in the house
- Locate the cleanout and clear a path to it
- Have any site plan or as-built drawing handy
