In Silver Spring, where many houses date from the 1950s and 1960s, hydro jetting is how a plumber scrubs a main drain or sewer lateral back to full width, cutting roots and washing out scale and grease that a cable leaves behind. A camera check usually comes first on older pipe. Call the number on this page to be connected with a local plumber in Silver Spring.

Older drain lines inside the Beltway
The median home in Silver Spring was built in 1964, and the older residential neighborhoods ringing the downtown, such as Woodside Park and Long Branch, have decades of mature trees above their sewer laterals. Pipes from that period are often cast iron inside the house and clay or iron underground, with joints that roots can find. WSSC Water provides public water and sewer here. Keep in mind that the Silver Spring mailing area is much larger than the census-defined community and stretches to places like Wheaton and Four Corners, but WSSC serves that wider area too.
What to do right now
- Stop using water in the house: no laundry, dishwasher or showers until the line is open.
- Check whether the lowest drain, usually a basement floor drain or laundry tub, is holding water. That points to the main line rather than a single fixture.
- Ask a neighbor if their drains are slow. If several houses are affected, call WSSC Water's emergency line at 301-206-4002 because the public sewer may be blocked.
- If only your house is affected, find the cleanout if you can, often a capped pipe in the basement or near the front foundation.
- Call a plumber and mention the age of the house and any earlier sewer work.
Signs and what they usually mean
| Symptom | Likely cause |
|---|---|
| Basement floor drain fills when the washer empties | Restriction in the main line past the laundry connection |
| Toilet bubbles when a sink drains | Partial blockage forcing air back through the fixtures |
| Line clears with a cable, then clogs again within months | Roots or a thick coating left on the pipe wall |
| Cable comes back with fine root hairs | Roots growing in through a joint in the lateral |
| Sewer smell near the cleanout or floor drain | Standing waste behind a partial clog |
What affects the cost
- Cleanout access, including whether a finished basement hides it
- Length of the lateral out to the street
- Roots versus grease and paper
- Camera inspection before and after jetting
- Night or weekend timing
If the camera finds a cracked or separated section, the job becomes a repair, which WSSC Water requires to be done by a plumber registered with WSSC under a WSSC permit.
