Lorton's housing is mostly from recent decades, so shower trouble here usually comes from a worn cartridge, diverter or seal in a pressure-balancing valve rather than an old corroded body. Those parts normally come out through the trim. Call the number on this page to be connected with a local plumber in Lorton.
Lorton in short
Lorton sits along I-95 and Route 1 between Fort Belvoir and the Occoquan River. In ZIP 22079, fewer than one in five homes were built before 1980, and the 2000s were the biggest building decade, much of it around Laurel Hill. That makes most bathrooms here fairly modern, with single-handle pressure-balancing valves from mainstream brands. Fairfax Water's Griffith plant, which treats Occoquan Reservoir water using ozone and granular activated carbon, is just outside Lorton, and Fairfax Water also draws on the Potomac. Its water is moderate to hard, with Griffith samples running about 77 to 147 mg/L of hardness, so scale on cartridges builds slowly but steadily.
Steps to take right away
- If water keeps running, close the house's main shutoff. Newer homes often have it in the basement or a utility closet near the water heater.
- If only the head drips, it can usually wait for a scheduled visit; put a bucket under it if it's heavy.
- Check the ceiling below. Many Lorton bathrooms sit above living space, and stains there point to a leak behind the wall.
- Photograph the trim. A picture of the handle and plate helps identify the brand and cartridge.
- Don't over-tighten. Cranking the handle closed harder wears the cartridge faster.
Common symptoms
| What happens | Usual cause |
|---|---|
| Head drips after shutoff | Cartridge seals worn |
| Water goes cold when the dishwasher runs | Pressure-balancing spool sticking |
| Handheld or rain head won't switch | Diverter cartridge worn |
| Stiff or gritty handle | Scale on the cartridge |
| Hot water runs short at the shower only | Limit stop set too low |
Cost factors
- Cartridge or diverter replacement versus a new valve
- Multi-outlet showers that need brand-specific parts
- Access from a closet or through tile
- Repairing a ceiling or wall if a leak went unnoticed
- Permits through Fairfax County Land Development Services, which issues building and trade permits for unincorporated Lorton, if the job calls for one
