Gainesville is served by Prince William Water, which owns the meter and makes owners responsible for lines and connections on private property. A leak between the meter and your house is a job for a plumber, who can repair the damaged section or install a new line. Call the number on this page to be connected with a local plumber in Gainesville.
Gainesville conditions
Gainesville grew from a railroad and farm crossroads at I-66 and Route 29 into a fast-growing area of newer subdivisions and big shopping centers, mostly since the mid-1990s. Only about 4% of homes in ZIP 20155 were built before 1980, and the 2000s were the biggest building decade. That means service lines are generally young, and when they leak, the cause is usually a fitting, a joint disturbed by settling soil or damage from irrigation, fencing or landscaping.
Prince William Water notes that most of its demand in the county's rural area falls within Gainesville-Wellington. It buys most of its water from Fairfax Water, and some western-county customers receive water treated at the City of Manassas plant from Lake Manassas. For outlying properties, service varies by address, so check your bill. Prince William Water's customer service line is (703) 335-7950, and its Emergency Dispatch for main breaks and after-hours problems is (703) 335-7990. Plumbing permits for unincorporated Gainesville come from Prince William County Development Services' Building Development Division.
Repair or replace
| Situation | Section repair | New line |
|---|---|---|
| A nicked pipe from a fence or irrigation dig | Usually the answer | Rarely needed |
| Joint that separated as soil settled | Good fit | Only if several joints are failing |
| Repeat leaks on the same run | Short-term | Worth pricing |
| Poor pressure throughout | May not help | Can fix an undersized or damaged line |
Signs to look for
- A wet patch that stays after the sprinklers are switched off
- The meter's leak indicator spinning with everything closed
- Pressure loss in every bathroom at once
- Water near the main valve in the garage or utility room
Timing and seasons
Summer irrigation can hide a service line leak, and winter freezes can split a line where it runs shallow near a garage or porch. Prince William Water switches to free chlorine for a period each spring, which can change taste briefly and isn't a pipe problem. Plumber Washington DC Pros is a referral service, not a plumbing company; your call reaches an independent local plumber who serves Gainesville. A slow yard leak can usually wait for a scheduled visit, but water entering the house calls for the main valve and a same-day call.
