In Alexandria, a leaking or temperamental shower usually traces back to a cartridge, washer or seal inside the valve, and many of the city's older bathrooms have valves that are decades old. A plumber can often rebuild the valve from the front; a corroded or unsupported body gets replaced. Call the number on this page to be connected with a local plumber in Alexandria.
Alexandria homes and their shower valves
Inside city limits, Virginia American Water supplies the taps, buying treated water from Fairfax Water's Potomac and Occoquan plants. The company's annual report puts total hardness between about 78 and 191 ppm, so scale can build on cartridges and diverters at a pace that varies through the year. Water is disinfected with chloramine, with a switch to free chlorine during spring flushing.
The city's median home dates to about 1974, and that average hides a wide spread: historic Old Town houses, prewar Del Ray streets, and newer towers in Potomac Yard and the West End. Older bathrooms may still have three-handle tub-and-shower valves or early single-lever designs whose makers no longer stock parts. Condo buildings add a wrinkle, since shutting water to one unit sometimes means coordinating with building staff.
Many addresses with an Alexandria mailing label are actually unincorporated Fairfax County, served by Fairfax Water and permitted by the County rather than the City's Code Administration. Check your bill and tax record if you're unsure.
Rebuild or replace?
| What you see | Typical fix | What to know |
|---|---|---|
| Drip from the head after shutoff | New cartridge, washer or seat | Done through the trim in most cases |
| Sudden hot or cold bursts | Pressure-balancing cartridge | Scale is a common cause |
| Three-handle valve leaking at stems | Stem and seat rebuild, or a new valve | Depends on whether parts still exist |
| Green corrosion or a cracked body | Valve replacement | The wall or tile has to open |
| Spout and head running together | Diverter or spout replacement | Often a quick repair |
Signs to watch
- A handle that creeps or won't hold its position
- Hot water that fades sooner at the shower than at the sink
- A musty smell or soft drywall behind the shower wall
- Mineral rings around the trim plate that return after cleaning
Timing and seasonal notes
In winter, a shower on an exterior wall of an older Alexandria house can see its supply lines get cold enough to freeze on the worst nights, which may split a fitting at the valve. Keeping the bathroom door open and heat on helps. In spring, a stronger chlorine smell during the flushing period is normal and doesn't mean the valve is failing. For permit questions on in-city work, the City's Department of Code Administration runs the Permit Center.
