Hydro jetting clears an Upper Marlboro drain or sewer line with high-pressure water that strips away grease, sludge and roots, giving a longer-lasting result than snaking. Because the Upper Marlboro area mixes public sewer with rural properties, the plumber will want to know where your line goes. Call the number on this page to be connected with a local plumber in Upper Marlboro.

The Town of Upper Marlboro is tiny, with about 650 residents around the county courthouse, but the Upper Marlboro mailing area covers about 77 square miles, from horse-farm countryside to growing developments like Westphalia. The median home there dates to 1982. WSSC Water runs water mains serving the Upper Marlboro area, and its Western Branch wastewater treatment plant is in Upper Marlboro, but sewer and water service in outlying rural parts varies by address. Some properties may use private wells or private onsite wastewater systems, so check your bill for a WSSC sewer charge.
What to do now
- Stop using water in the house until the line is cleared.
- Check the lowest drain. If it's filling, the main line is the problem.
- If you're on WSSC sewer and a manhole is overflowing or neighbors are backing up, call WSSC Water at 301-206-4002.
- If your home isn't on municipal sewer, don't run extra water trying to flush the clog.
- Call a plumber and say whether you're on public sewer and where the cleanout is.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Several drains slow at once | A blockage in the main building drain |
| Clogs that keep returning | Grease or roots left in the pipe after cabling |
| Gurgling as the washer drains | A partly blocked main or a venting problem |
| Soggy ground along the line in the yard | A break or a backed-up line to a private system |
| Only one sink slow | A branch clog, often fixed without jetting |
What affects the cost
- The length of the line, which can be long on rural lots
- Whether the home is on public sewer or a private onsite system
- Cleanout access
- Roots versus grease
- A camera inspection and the time of day
Jetting is cleaning, not new plumbing. If a repair turns up, Prince George's County sends all plumbing permits to WSSC Water, and the town links to the county's DPIE for building permits. Sewer service line repairs need a plumber holding a WSSC license. Large-lot homes near the Western Branch of the Patuxent and out toward Brock Hall often have long service lines, so jetting there may take more hose and more time than in a compact subdivision.
