Superior Sprinkler Systems installs and repairs irrigation systems in Purcellville, VA, and the surrounding western Loudoun County countryside. We design systems for larger lots and homes on private wells, repair aging ones, test backflow preventers, and handle spring start-ups and winterizations. Family-owned in Loudoun County since 1991.
Purcellville is a different kind of irrigation job than eastern Loudoun County. Lots are larger, yards often roll with the foothills of the Blue Ridge, and many homes just outside town limits draw their water from a private well instead of a public utility. A system that works well here has to be designed around the water source first and the lawn second.
Our shop is on Azalea Lane in Dulles, and western Loudoun has been part of our service area since 1991. We schedule Purcellville work in efficient routes so you get the same family-owned crew and the same response you would get closer to our shop.
A well can only deliver so many gallons per minute, and that number sets the limits of the whole system. Before we design anything, we measure the flow and pressure your well and pressure tank can actually sustain. Zones are then sized so the pump is not short-cycling and the house still has water while the sprinklers run. In some cases that means more, smaller zones or drip in the beds instead of spray.
We also look at water quality. Iron and sediment can clog nozzles and stain walks and siding, so we choose heads and filtration accordingly. Even on a well, a backflow device is good practice to protect your drinking water from anything pulled back from the yard.
Purcellville properties often run an acre or more, with long frontages, slopes and open turf. We use long-throw rotors for open areas, separate zones for slopes so water has time to soak in instead of running off, and cycle-and-soak programming on the controller. Many homeowners choose to irrigate the front lawn and main living areas rather than every square foot, which keeps both installation cost and water use in check.
Homes inside town limits are generally served by the Town of Purcellville water system. Irrigation connected to public water needs an approved backflow assembly, and it has to be tested by a certified tester. Our DPOR certified backflow testers perform the test and handle the paperwork, and we confirm the filing requirements for your address. Our backflow testing and certification page explains the process.
We work throughout Purcellville, from the neighborhoods near Main Street and the W&OD Trail to the newer subdivisions around town, along with rural properties outside town limits. We also serve nearby Round Hill, Hamilton and the farm and estate properties along Route 7 and Route 9. Whether your yard is a quarter acre in town or several acres in the country, we design the system around how you actually use the property.
The water source. We measure flow and pressure from the town connection or your well and pressure tank before designing a single zone.
Backflow prevention. Required on irrigation connected to public water and good practice on a well. We install it where it is easy to test and easy to drain for winter.
Controller. Garage wall, barn or an outdoor-rated enclosure. WiFi and weather-based scheduling let you manage a large property from your phone.
Parts. Rain Bird, Irritrol and Hunter equipment, WaterSense certified, with rigid PVC in the ground, long-throw rotors for open turf, sprays for tight areas, and drip through beds.
Design. Drawn by a licensed irrigator after utilities are located, with head-to-head coverage and any dry spot corrected under warranty.
Warranty. Three years against defects, with first year winterization, spring start-up and backflow test included.
Site visit and quote. We check your water source, measure the property, look at grade, sun and planting, and talk through which areas matter most. You get a written, itemized estimate within 24 hours.
Permits and marking. We pull any permits and arrange utility locating. Head positions and trench lines are flagged before anything is cut.
Install days. Trenching, pipe, valves, heads, wiring and controller. Larger Purcellville properties usually take two days or more, depending on acreage and zones.
Start-up and handover. Zone-by-zone testing, arc and nozzle adjustment, seasonal run times, backflow test filed where required, warranty activated, and a walkthrough of the controller.
Superior Sprinkler Systems is a family-owned irrigation company. Chris is our owner and founder, Brian is our general manager, and Dylan leads irrigation design and installation. Our own crews do the work, every layout is drawn by a licensed irrigator, our backflow testers are DPOR certified, and we carry full insurance. You can read more about our team or see what our customers say.
Along with Purcellville, we install and service irrigation systems in nearby Leesburg, Aldie and Lansdowne, and across Loudoun County.





Three years of cover against defects, and your first year of winterization, spring start-up and backflow testing comes with it.
Buried utilities are located and marked first. A licensed irrigator then draws your layout around the actual run lengths and the grade on your lot, so pressure holds from the tap out to the far boundary. Head-to-head coverage is guaranteed and any dry spot is a warranty item.
Moisture sensing, weather-based control and zoning, including WiFi-enabled options. The system waters when the lawn needs it rather than on a fixed timer, which keeps consumption down and keeps you inside any conservation advisory the Town of Purcellville has in effect.
Decades of installations behind every job, carried out with the care that keeps water going where it should and keeps disruption to your Purcellville property to a minimum.
Connected inside or outside the house to suit your plumbing, with a master shut-off valve placed somewhere you can actually reach in a hurry.
Fitted to every system, keeping water that has stood in a buried lateral away from your drinking supply. Installed to the standard the Town of Purcellville accepts, then tested and filed by our DPOR-certified staff.
The garage is the usual spot. If that does not suit your layout, a basement, a shed or a protected outdoor enclosure does the job just as well.
Rain Bird, Hunter and Irritrol components throughout. Rigid PVC in the ground rather than flexible tubing, because PVC is what survives decades of freeze and thaw in Virginia clay. Rotors for open turf, sprays for tight geometry, drip through beds.
We stay on the account. Adjustments, seasonal work, repairs and upgrades all come from the same crew that built the system.
We walk the property with you, test pressure and flow at the tap, and look at grade, soil and what you actually want watered. Your written estimate follows within 24 hours.
Permits pulled in our name, utilities located and marked, and the layout flagged so you can see where every head and trench falls before we start. Trenches closed, surface restored, every zone tested.
Every zone run, arcs set, the schedule programmed for the season, your backflow test filed and the warranty started. Then we show you how to run it.
Q: Can I run a sprinkler system off my well?
A:Yes, if the system is designed around what the well can deliver. We measure flow and pressure from your well and pressure tank, then size the zones so the pump is not overworked and the house still has water while the system runs.
Q: Do you serve homes outside Purcellville town limits?
A:Yes. We work throughout western Loudoun County, including rural properties around Purcellville, Round Hill and Hamilton.
Q: Do I need a backflow preventer in Purcellville?
A:Irrigation connected to public water needs an approved backflow assembly that is tested by a certified tester. On a private well, a backflow device is still good practice to protect your drinking water. We install and test both.
Q: Should I irrigate my whole property?
A:Not necessarily. On larger lots, many homeowners irrigate the front lawn and main living areas and leave pasture or outer areas natural. We help you decide where irrigation adds the most value.
Q: How long does an installation take on a larger lot?
A:Most Purcellville installations take two days or more, depending on the size of the area, the number of zones and the terrain.
Q: When should I winterize in western Loudoun?
A:Western Loudoun often sees its first hard freeze a little earlier than the eastern county, so we recommend scheduling in late October or early November.
