Set zones, head type, turf and pipe. Counts and a parts band update as you type.

The backflow band spans four listed Febco 765 assemblies. At a glance 1. Contractors price by the zone, not by the lawn. One zone is a valve, a box, a lateral run and a controller station. 2. Head type sets the head count. A rotor holds about 900 sq ft, a fixed spray 225. 3. The backflow device class is set by local code, and a licensed tester signs it off. ## Irrigation system cost is a zone count, not a lawn size Two yards of the same square footage can price hundreds apart. Sun, shade, beds and turf want different run times, so each area becomes its own zone. A zone is whatever one valve turns on: a valve, a box, a lateral run and a controller station. ## What one zone costs in parts | Part | Named product | Low | High | | --- | --- | --- | --- | | Zone valve | Rain Bird 100-DV 1 in. | $17.05 | $27.72 | | Valve box | NDS 111BC 10 in. | $20.95 | $26.18 | | Lateral pipe, a foot | Blu-Lock 1 in. 300 ft | $0.57 | $0.75 | | Fixed spray head | 1804 body plus 15Q nozzle | $2.92 | $4.30 | | Rotor head | 5004-PC, standard nozzles | $10.15 | $16.75 | | Rotary nozzle head | 1804 body plus R-VAN14 | $6.50 | $10.88 | Low is Sprinkler Warehouse, high SiteOne, read September 11, 2026. No publisher states an installed price a zone, so this page prints none. ## Head type sets the head count Rain Bird rates each nozzle at a spacing of half its diameter of throw, the radius. Each head holds one square of that spacing, with part circle arcs on the edges. | Head | Radius | Precip | Turf a square | | --- | --- | --- | --- | | 15Q fixed spray, 30 psi | 15 ft | 1.58 in. an hour | 225 sq ft | | 5000-MPR-30 rotor, 45 psi | 30 ft | 0.62 in. an hour | 900 sq ft | | R-VAN14, 45 to 270 degrees | 8 ft to 14 ft | matched 0.6 | 196 sq ft | Four times the heads on a spray zone, and the reason you never mix the two on a valve. Rain Bird prints a matched 0.6 in. an hour across 5000 rotors and R-VAN nozzles, so they share a zone, on MPR nozzles bought separately. ## Turn the zone count into a priced job SimplyWise Cost Estimator turns a photo into an itemized estimate in about 6 seconds, with material and labor lines. Pricing is $29.99/mo or $239.99/yr, about $20/mo on annual, with a 7-day free trial. ## The spine you buy once, and the code that prices it Point of connection, main line, backflow and controller get bought once. The controller steps in jumps: a Rain Bird ESP-TM2 runs $108.85 to $175.74 at 6 stations and $268.85 to $392.04 at 12. Zone seven is the expensive one. The backflow assembly is the code line, and its class is not your pick. Model plumbing code accepts an atmospheric vacuum breaker, a pressure vacuum breaker assembly or a reduced pressure principle assembly. Louisiana amended that section: once a system has separate zones, only a pressure vacuum breaker or a reduced pressure assembly passes. Texas writes the hazard test into rule. Under 30 TAC 344.51(d)(2) a property on an on site sewage facility makes the system a health hazard, so only a reduced pressure assembly qualifies. A pressure vacuum breaker sits 12 inches above all downstream piping under 344.50(b)(3)(B) and the highest opening. Under 344.50(e) a licensed tester checks it on installation, then annually on a health hazard system. Price the class your inspector accepts. Four listed 1 in. Febco 765 assemblies ran $221.62 to $508.09 that day, and the spread is configuration. ## What the labor side pays Irrigation falls under Landscaping and Groundskeeping Workers, whose federal job definition names sprinkler installation outright. Its May 2025 national hourly median was $18.82, the 90th $27.28. If the point of connection goes to a licensed plumber, that occupation median is $30.67. Both are employee wages, and OEWS skips the self-employed. ## What pushes irrigation system cost up A vibratory plow slices a slot and pulls pipe behind the blade. A trencher opens a real ditch, which roots, shallow utilities and hardscape force, plus spoil and backfill hours. No maker publishes an hours a foot figure, so the calculator asks for yours. Slope forces check valves so low heads stop draining the lateral. The quiet one is meter size, which caps gallons a minute, then heads a zone, then zone count. ## Price a sprinkler system in four steps 1. Split the yard into zones Group turf with turf, beds with beds, then read the meter. 2. Pick the head type, then count Turf area over the radius squared gives heads per zone, rounded up. 3. Price the spine separately Point of connection, main line, backflow and controller are one line. 4. Put labor on your own sheet Set crew hours off the method and site, then apply your rate. ## Keep reading - Construction Calculators (https://www.simplywise.com/blog/construction-calculators/) - Landscaping Cost (https://www.simplywise.com/blog/landscaping-cost/) - Plumber Cost (https://www.simplywise.com/blog/how-much-does-a-plumber-cost/) ## Sources ### Manufacturer charts - Rain Bird MPR nozzle chart (https://www.rainbird.com/sites/default/files/media/documents/2018-02/ts_MPRNozzles.pdf) (15Q; 2026-09-11). - Rain Bird 5000 Series MPR chart (https://www.rainbird.com/sites/default/files/media/documents/2020-09/5000-series-mpr-nozzle-performance-chart.pdf) (2026-09-11). ### Prices read live - Sprinkler Warehouse (https://www.sprinklerwarehouse.com/rain-bird-dv-inline-valve-1-in-fpt-100-dv-npt) (2026-09-11). - SiteOne Landscape Supply (https://www.siteone.com/en/100dv-rain-bird-dv-globe-valve-plastic-1-in-fipt-x-fipt/p/27385) (2026-09-11). ### Code and wages - TCEQ RG-478 (https://www.tceq.texas.gov/goto/rg-478) (30 TAC 344.50, 344.51; 2026-09-11). - IPC 2015 as adopted, unamended (https://up.codes/viewer/virginia/ipc-2015/chapter/6/water-supply-and-distribution) (608.16.5; 2026-09-11). - Louisiana Health, IPC as amended (https://ldh.la.gov/assets/oph/Center-EH/engineering/CCC/2015_IPC_CCC_Requirements_Amended.pdf) (608.16.5; 2026-09-11). - BLS OEWS flat file (OEUN000000000000037301108; 2026-09-11). ### Product - SimplyWise Cost Estimator, App Store (https://apps.apple.com/us/app/simplywise-cost-estimator/id6670619664) (4.8; 2026-09-09). ## Common questions about irrigation system cost ### Zones and heads **How is an irrigation system priced?** By the zone. Each zone buys a valve, a box, a lateral run, a controller station and its heads. **How many sprinkler heads does one zone need?** Divide the turf by the radius squared. A 15 ft spray square is 225 sq ft, a 30 ft rotor square 900. **Can I put spray heads and rotors on the same zone?** No. A 15Q lays down 1.58 in. an hour and a 5000 rotor 0.62, so half the zone floods and the rest stays dry. ### Backflow, code and labor **Why does a sprinkler system installation cost include a backflow preventer?** The system is a direct cross connection to drinking water. Model code accepts an atmospheric vacuum breaker, a pressure vacuum breaker or a reduced pressure assembly, and local code narrows that. **Does the backflow assembly have to be tested?** In Texas, yes. Rule 344.50(e) has a licensed tester check it on installation, then annually on a health hazard system. **Can SimplyWise price an irrigation job from a photo?** Yes.
