In an Olney plumbing emergency, close the main shutoff to stop the water and get everyone outside if you smell gas, then call 911 and your gas utility from a safe spot. After that, call the number on this page to be connected with a local plumber in Olney.

Olney's water, sewer and housing
Olney grew up around the crossroads of Georgia Avenue and Olney-Laytonsville Road, and most of it was farmland until the 1960s. The core is on WSSC Water for both water and sewer, and the Triadelphia and T. Howard Duckett reservoirs on the Patuxent River, part of WSSC's supply, lie along the area's northern edge. The outskirts differ: public water was extended to Mt. Zion to relieve well problems there, and some outlying properties sit outside the planned sewer envelope or can't be served by gravity sewer, so they depend on private onsite wastewater systems.
The median Olney home was built in 1986, and many houses from that period still have their original shutoff valves while running on their second or third water heater. WSSC reports that water from its Patuxent plant averages about 64 mg/L of hardness and Potomac plant water about 140 mg/L, and which plant feeds a given street varies. Harder water builds scale in tanks faster.
Which number fits the problem
| Problem | Call |
|---|---|
| Main break or flooding at the curb | WSSC Water Emergency Service Center, 301-206-4002 |
| Burst pipe or leaking tank inside | A plumber, after the main is closed |
| Backup in a home on public sewer | A plumber to clear the house line |
| Backup in a home with an onsite system | A plumber who works on private systems |
| Gas odor | Leave, then 911 and the gas utility on your bill |
Signs to act on now
- A ceiling stain that is growing or dripping
- Sewage odor with gurgling from a basement shower or floor drain
- A sump pit filling while the pump stays silent
- Water spreading from under the water heater or washer
Timing through the year
Hard freezes are the busiest stretch, especially for hose bibs, garage lines and pipes in exterior walls. Spring brings irrigation start-ups, and WSSC requires testable irrigation backflow assemblies to be tested each year at start-up by a certified cross-connection technician; a device that froze over the winter often reveals itself then. Summer storms put sump pumps to the test. Expect higher charges at night and on weekends, and ask about them before the visit is set.
