The City of Falls Church gets its water from Fairfax Water, as does most of the wider Falls Church mailing area, so a home here almost never has a private well pump. Pressure problems usually come from an aging regulator, a valve or the line into the house, while some homes have sump or booster pumps. Call the number on this page to be connected with a local plumber in Falls Church.
A quick local picture
Falls Church is a small independent city just inside the Beltway where Route 29 and Route 7 meet, with a median build year of 1971. Fairfax Water provides the water; the City runs its own sewer system. The Falls Church mailing area spreads well past the city into Fairfax and Arlington counties, including places like Seven Corners, so utilities and permit offices depend on the address. Whatever the address, the water arrives pressurized from a public system. The pumps that do turn up in Falls Church homes are basement sump pumps, the occasional ejector for a lower-level bathroom, and a few boosters in taller additions or homes at the top of a slope.
What to do now
- Test faucets on each floor to see whether the drop is house-wide.
- Check with a neighbor; if they are low too, call Fairfax Water at 703-698-5800.
- Make sure the main shutoff is fully open; older valves can stick partway.
- If you have a sump or booster pump, check its breaker and listen for it running.
- Turn off a pump that runs nonstop or trips its breaker until a plumber can check it.
| Symptom | Likely cause |
|---|---|
| Weak pressure everywhere, neighbors normal | Regulator, main valve or a leak on the owner's line |
| Weak flow at one tap | Clogged aerator or cartridge |
| Pressure spikes and banging pipes | Regulator that has failed open |
| Booster pump cycles rapidly | Waterlogged pressure tank |
| Sump pump hums, pit stays full | Jammed impeller or stuck float |
Cost factors
- Regulator or valve replacement compared with pump work
- Locating a leak on the buried line from the meter
- Access in older basements and crawlspaces
- Permits from the City's Code Administration office, or the county office for addresses outside the city
Fairfax Water's hardness runs roughly 70 to 185 mg/L depending on the plant and season. After fifty years in an older Falls Church house, mineral buildup in a regulator or in fixture cartridges is a far more likely explanation for weak flow than a pump. If the house has its original pipe inside the walls, narrowing from corrosion can also play a part, and a plumber can check for that during the same visit.
