The Town of Leesburg requires every testable backflow device on its water system to be tested once a year by a DPOR-certified tester, and results for home irrigation devices are due to the Town by June 1. If your test is due, a device failed or you need a new one, call the number on this page to be connected with a local plumber in Leesburg.
What happens when you call
The call reaches an independent plumber who works in Leesburg. Have the Town letter or your last report nearby, say whether the device protects a sprinkler system, a pool or a business, and ask the plumber to confirm their DPOR backflow certification. If the device is leaking, shut the irrigation supply or the main valve before the visit.
On site, the tester connects a gauge to the test cocks and checks each check valve and relief valve against the required readings. A passing result goes on the Town's Backflow Test Report Form. A failing device is repaired or replaced and tested again.
What affects the cost
- Pass on the first try or not. A rebuild kit, labor and a retest add to the visit.
- Assembly type. A reduced pressure unit costs more to service than a pressure vacuum breaker.
- Replacement. New work brings parts and permits.
- Timing. Booking in late May, right before the deadline, leaves little room for a repair.
Local conditions in Leesburg
Leesburg runs its own water and sewer utility, separate from Loudoun Water, and its Cross Connection Control Program exists because Virginia Department of Health waterworks regulations call for one. The rules are specific: all testable devices are tested yearly, results go to the Town on its form, home irrigation results are due by June 1, and a device that fails needs a passing report within 15 days. Non-residential sites are inspected based on their hazard level.
Town water is drawn mainly from the Potomac River and treated at the Kenneth B. Rollins plant, and it runs moderately hard, typically 100 to 150 ppm. Most homes date from the growth around the historic downtown, with a median year built of 1993, so sprinkler assemblies installed with those subdivisions are reaching the age where checks and seals wear. The Town also serves some customers outside its limits, and service near the edges varies by address; if your bill comes from Loudoun Water, follow Loudoun Water's program instead. A new or relocated assembly needs a Town of Leesburg Zoning Permit first, then a permit from Loudoun County Building and Development.
Before the plumber arrives
- Clear plants and mulch away from the device
- Find the irrigation shutoff inside the house
- Have the Town letter, account number or last report ready
- Turn off the sprinkler controller so zones do not start mid-test
- Know whether a pool or fountain also ties into the water line
