When a pipe bursts in Annandale, shut the main water valve immediately and keep clear of outlets the water has reached. A plumber can find the split, replace the damaged length and look over the older pipe around it. Call the number on this page to be connected with a local plumber in Annandale.
Why Annandale homes see bursts
Annandale grew fast after World War II, and the median home here was built in 1968. Around Lake Barcroft, Ravensworth and the streets off Little River Turnpike, many houses still have original copper or steel supply lines, sometimes joined to newer pipe from later remodels. Older pipe and mixed materials mean more joints that can let go when water freezes inside them, and basements and crawlspaces along exterior walls get cold fast.
Fairfax Water supplies Annandale, drawing from the Potomac River and the Occoquan Reservoir. It owns the meter; the underground line from the meter or street valve to the shutoff inside the house belongs to the homeowner. Some houses built between 1971 and 1980 have the meter indoors. For a break in the street or at the meter, call Fairfax Water customer service at 703-698-5800. Fairfax Water keeps an online map of service line materials and asks owners to report what their side is made of.
Patch or replace?
| Finding | Common repair | Things to weigh |
|---|---|---|
| One freeze crack in otherwise sound copper | Replace a short piece | Usually the end of it if the rest is healthy |
| Galvanized steel that rusted through | Replace to the next solid joint | Steel near the break is often thin as well |
| A joint between old and new pipe gave way | Rebuild the transition | Proper transition fittings matter between metals |
| Third or fourth leak in a few years | Price a branch or whole-house repipe | Patches add up and walls get opened repeatedly |
Signs to watch
- A brown ring forming on the ceiling below a bathroom
- Rust-colored water after the main is turned back on
- A musty basement wall that stays damp
- Faucets that lose pressure one by one
Timing and the seasons
The riskiest stretch is the morning after the first deep freeze of winter, and again during a thaw, when ice in a cracked pipe melts and water starts to flow. Disconnect hoses in the fall and close any inside valve that feeds an outdoor faucet. Fairfax County Land Development Services issues permits for new, repaired or relocated plumbing; a short like-for-like patch generally falls outside that, while a repipe will not.
