Mount Rainier is an early-1900s streetcar suburb on the DC line, and its older basements often need a sump pump, or a better one, to stay dry after heavy storms. A plumber can repair a failing pump, replace it, add a backup or install a pit where there is none. Call the number on this page to be connected with a local plumber in Mount Rainier.
Mount Rainier conditions
Mount Rainier borders the District's Woodridge neighborhood, and much of the city is a National Register historic district filled with Sears kit houses and Craftsman homes. The median home was built in 1952. Basements from that era were rarely designed with drain tile and a pit, so water management here is usually a retrofit: a basin cut into the floor years later, sometimes with a small pump and a discharge pipe that empties just outside the wall.
WSSC Water provides water and sewer service in Mount Rainier; the City does not run its own system. For sewage overflowing from a public manhole or the street, call WSSC at 301-206-4002. Permits involve more than one office. WSSC Water issues plumbing permits and inspects the work, while the City's Code Compliance Department issues City building permits and notes that some permits come from Prince George's County. Cutting a new pit in a basement floor is the kind of project to ask about first.
Options for an older basement
| Option | Best for | Notes |
|---|---|---|
| Repair the existing pump | A failed float, switch or check valve | Only worth it if the motor is in good shape |
| Replace the pump | A weak, loud or seized motor | Often paired with a new check valve |
| Deepen or replace the basin | Small, cracked retrofit pits | Gives the pump room to work properly |
| Install a new pit | Basements with no pit that flood each storm | Larger job; may involve permits |
| Battery backup | Finished space, frequent outages | No tie to the water supply |
Signs worth a call
- Water around the pit lid or across the floor after a storm
- The pump only works after you jiggle the float or cord
- A sewer smell near the pit or a floor drain
- Peeling paint or white crust at the base of the walls
Timing
Old houses tend to show their weak spots during late-winter thaws and long spring rains, so test the pump before then. Summer thunderstorms bring fast, heavy water and power outages at the same time, which is when a backup earns its place. In January and February, check the outdoor end of the discharge for ice.
