About Upper Marlboro addresses
The incorporated Town of Upper Marlboro is tiny and dominated by county government, but the Upper Marlboro postal area covers about 77 square miles of subdivisions, horse farms and countryside. Most calls with an Upper Marlboro address come from outside the town. WSSC Water runs mains serving customers in the area and its emergency line for breaks in the street or at the meter is 301-206-4002. In outlying rural parts of the postal area, water service varies by address, so check your bill; if you get no water bill, your home likely has a private well. The median home in the area was built in 1982.
What to do in the first minutes
- Stop the water. Close the main valve, or for a well, switch off the pump breaker and close the valve at the pressure tank.
- Turn off electricity to any wet room at the breaker panel.
- Drain the pipes by opening the lowest faucet in the house.
- Protect the water heater by switching it off or to pilot.
- Get belongings out of the water and start drying.
- Take photos for your insurer.
- If you smell gas or propane, leave the house first, then call 911 and your gas utility or propane supplier from outside.
What you see and what it usually means
| Symptom | Likely cause |
|---|---|
| Water through a basement ceiling | Split supply pipe or failed fitting above |
| Well pump running with no taps open | Leak somewhere on the pressurized side |
| Barn or outbuilding line spraying after a freeze | Unheated pipe that froze and cracked |
| Wet lawn along the water line route | Break in the buried line to the house |
| Outdoor faucet leaking inside the wall | Hose bib that froze with a hose attached |
What drives the cost
Expect the price to depend on access, the amount of pipe involved and timing. A crack in exposed basement pipe is quick; a break inside a finished wall or along a long buried line on a large lot takes more work. Well homes may need the pump, switch or tank checked after a leak. Plumbing permits in Prince George's County come from WSSC Water, and water heater replacements require one; service line and gas work must be done by a plumber or gasfitter holding a WSSC license. Night and weekend visits cost more.
