Hyattsville is on WSSC Water's sewer, and its housing is among the older stock in Prince George's County, with a median home built in 1963 and about half the homes older than that. Old cast iron and clay drain lines make main line backups and root problems a regular call here. Call the number on this page to be connected with a local plumber in Hyattsville.

Signs your Hyattsville drains need attention
- A basement floor drain or laundry tub fills with gray water
- The toilet rocks the water level or gurgles when the tub drains
- Bathroom sinks on the upper floor drain slower each month
- Black flakes or rusty grit come up when a drain is plunged
- Sewer odor near the base of an old cast iron stack
Rust-colored debris from a plunged drain is a clue that cast iron is scaling inside. Any backup at the lowest drain in the house means stop using water until the main is opened.
What makes Hyattsville drains different
The city's National Register historic district holds Victorian houses from the late 1880s alongside interwar Sears kit homes and Arts and Crafts bungalows. Homes of that age often still have original cast iron stacks inside and clay sewer laterals outside, and decades of tree growth along the older streets give roots a head start. Clay joints let roots in; cast iron rusts and scales until the pipe's inside diameter shrinks. Both trap grease and paper, so a cable that clears a clog today may not keep it clear for long.
WSSC Water provides water and sewer service here. Hyattsville has no city permits office: building permits go through Prince George's County, while plumbing permits and inspections come from WSSC. If sewage is coming up from a manhole or the street, call WSSC's Emergency Service Center at 301-206-4002.
Cost drivers
- Location: a single fixture trap versus the main line to the street.
- Pipe condition: old cast iron and clay may need a descaling head or jetting, and more care.
- Access: older houses often lack an outdoor cleanout, so the plumber may work through a basement cleanout plug or a pulled toilet.
- Diagnosis: a camera inspection adds cost but shows whether the line needs repair.
- Hour of the call: nights and weekends cost more.
