Springfield homes on Fairfax Water fall under its cross-connection program, which requires backflow assemblies on underground lawn irrigation to be tested at installation and every year after, and again after any repair or replacement. To book a test, fix a leak or replace a damaged device, call the number on this page to be connected with a local plumber in Springfield.
What happens when you call
You are connected with an independent plumber who serves Springfield, North Springfield, West Springfield and Newington Forest. Describe the device, what it protects and any notice you received, and ask whether the plumber holds the state backflow certification and is on Fairfax County's authorized list. If it is leaking hard, close the irrigation shutoff first.
The plumber tests the assembly with a calibrated gauge, records the readings and either reports a pass or explains the repair. Fairfax Water's cross-connection staff, at 571-722-7653, can answer questions about your device's status.
What affects the cost
- Result of the first test. Failures add rebuild parts and a retest.
- Device type. A reduced pressure assembly takes more time than a vacuum breaker or double check.
- Age and parts. Older models can be hard to find parts for, which tips the job toward replacement.
- Permits. New or replacement irrigation assemblies need a County plumbing permit.
Local conditions in Springfield
Springfield grew from about 1,000 residents in 1950 to more than 25,000 by 1970, and the median home was built in 1974. Most of these houses were not built with sprinkler systems; irrigation was added later, sometimes more than once, by different contractors. That history explains a lot of what plumbers find: assemblies in awkward spots, devices of mixed ages, and a few systems with no protection at all. Around the Springfield Interchange and Springfield Town Center, businesses can have their own assemblies on service lines and equipment.
Water here comes from Fairfax Water, drawing on the Potomac River and the Occoquan Reservoir, with some Fairfax Water customers receiving Washington Aqueduct water. The utility reports moderately hard to hard water, and over the years that leaves deposits on check seats. Unincorporated Springfield is permitted by Fairfax County Land Development Services, reached at 703-222-0801 or online through PLUS.
Before the plumber arrives
- Turn the sprinkler controller off
- Find the irrigation shutoff in the basement or utility room
- Clear plants and leaves around the assembly
- Pull out any previous test report or tag information
- Note any pool, hot tub or fountain tied into the water line
