The Town of Brookeville is on WSSC Water, which requires every testable backflow assembly, such as those on irrigation and fire sprinkler systems, to be tested each year and after installation, repair or relocation by a WSSC-certified cross-connection technician. Call the number on this page to be connected with a local plumber in Brookeville.

Signs you need a plumber for backflow
- A sprinkler or fire line device hasn't been tested in over a year
- Water leaks from the device or its test cocks
- A device split over the winter
- You are adding irrigation to an older property
- A hose-fed fountain, pond or tank has no protection
Local conditions in Brookeville
Brookeville is a tiny historic town, incorporated in 1808, and its housing is old even by Montgomery County standards: the median home was built around 1940. Montgomery County's Water and Sewer Plan lists WSSC Water for both water and sewer in the town. Beyond the town limits, the wider 20833 ZIP area may include homes on private wells, so outside the town confirm your water service before assuming WSSC rules apply.
The town sits close to the Triadelphia Reservoir on the Patuxent River, one of the reservoirs WSSC Water draws on for drinking water. That is a good reminder of why backflow protection exists: it keeps water from a yard, a fountain or a chemical line from flowing back into a public supply.
WSSC's Plumbing and Fuel Gas Code calls for a yearly test of every testable assembly and a test after installation, repair or relocation. Only plumbers registered with WSSC who are also certified cross-connection technicians may do that work. Homeowners are allowed to rebuild or replace non-testable devices only, such as a hose bibb vacuum breaker. The Town has its own planning and zoning authority, so a larger project may need a town approval alongside WSSC's plumbing permit.
What affects cost
