Brandywine combines a newer commercial center along US 301 and MD 5 with rural-tier land, so some properties are on WSSC Water and public sewer while others rely on private wells and onsite systems; it varies by address. WSSC issues plumbing and gas permits, and DPIE handles building permits. Call the number on this page to be connected with a local plumber in Brandywine.

What happens when you call
Tell us what kind of property it is, what stopped working and whether it is on public water or its own well. You'll be connected with an independent local plumber who takes commercial calls in Brandywine and nearby Cedarville and Baden. On a newer retail building the visit is often about fixtures, water heaters or backflow; on a rural parcel it may start with the pump, pressure tank or the drain line out to the onsite system. Ask how the first visit is priced and when the plumber can come.
Cost factors
- Whether the property is on WSSC or a private system
- The number of suites, restrooms or outbuildings involved
- Diagnostics such as camera inspection or pump testing
- Trenching distance on large lots
- Off-hours scheduling around store hours
- WSSC permits and inspections
Local conditions in Brandywine
Brandywine grew quickly after 2000, with Brandywine Crossing and new subdivisions; more than half of local housing units were built since 2010, alongside a pocket of 1950s and 1960s homes. New buildings rarely have pipe-material problems, but they do raise questions about warranty work, start-up adjustments and making sure backflow assemblies are registered and tested.
Prince George's County's water and sewer plan says WSSC supplies water from the Potomac and Patuxent rivers and that rural areas use individual wells. The 20613 ZIP code also reaches into Charles County, which is outside WSSC, so check who bills the property. Where WSSC serves the site, it is responsible for the line from the main to the property line and the owner takes over from there. Testable assemblies, such as fire sprinkler double checks and irrigation devices, must be tested every year and after installation or repair by a plumber holding a WSSC license who is a certified cross-connection technician, and dual check valves must be rebuilt or replaced every five years.
WSSC issues permits for and inspects plumbing and all natural gas and LP gas installations in the county, so gas or propane water heater replacements need a plumber or gasfitter with a WSSC license (Permit Services 301-206-4003). Washington Gas serves much of the county, but rural properties may have no gas mains. If anyone smells gas, leave first, then call 911 and Washington Gas at 844-WASHGAS (844-927-4427), option 1, or your propane supplier.
Before the plumber arrives
- Find the water bill or note that the property has its own well
- Locate the main shutoff, pressure tank or meter
- Gather backflow test records and installation paperwork
- Clear access to mechanical rooms and cleanouts
