Irrigation System Installation: What’s Included in a Professional Scope?

Professional irrigation system installation includes site assessment, zone planning, trenching, pipe and valve installation, sprinkler head placement, controller setup, backflow prevention, system testing, and full documentation.

A complete scope covers every step from water source to final calibration. For single-family rentals, expect 3-6 zones, 40-80 PSI water pressure requirements, and 2-5 days of installation work depending on property size.

At Breasy, we focus on single-family rental maintenance across 12 markets in 7 states. We’re not a nationwide service or commercial contractor, but within our markets, we’ve completed over 100K jobs, including irrigation installs that hold up season after season.

What Professional Irrigation Installation Includes #

The scope should list every component going into the ground, every test performed, and every document you’ll receive at completion. If a quote skips any of these, you’re not comparing apples to apples.

The Difference Between Professional Installation and DIY #

DIY irrigation kits run $200-$800 and look simple enough. The problem isn’t the parts—it’s what happens underground.

Professional installation includes pressure testing before a single trench is dug. Across our job history, we’ve found that DIY installs regularly fail within the first 18 months because of pressure mismatch: a system designed for 60 PSI won’t work on a property running 35 PSI at the spigot.

Professionals also pull permits where required, locate utility lines, and design zones based on actual GPM (gallons per minute) capacity. DIY systems skip all of this. The result: dry spots, flooded areas, and code violations that cost more to fix than professional irrigation services cost upfront.

Why Scope of Work Matters for Property Managers #

When you manage 20, 50, or 100 properties, a detailed scope of work becomes your quality control. It tells you:

• What components were installed
• Where each zone covers
• What warranty applies
• What baseline performance looks like

As GPS Renting noted, “Working with Breasy has been a game-changer for our properties”—confidence that comes from knowing exactly what was installed and having documentation to reference when questions arise.

Pre-Installation Assessment and Site Evaluation #

Before any trenching begins, a professional installation starts with three assessments. Skip these, and you’re guessing.

Water Pressure and Flow Rate Testing #

Every irrigation design depends on two numbers: PSI (pounds per square inch) and GPM (gallons per minute).

PSI measures the force pushing water through the system. Most residential systems need 40-80 PSI. Too low, and sprinkler heads won’t pop up or throw water far enough. Too high, and you’ll blow seals and waste water.

GPM measures volume. A system that needs 15 GPM to run a zone won’t work if your water meter only delivers 10 GPM. We test both at the point of connection before designing anything.

In our Phoenix market, we see 45-55 PSI on residential properties. Texas properties often run higher at 60-75 PSI, which affects head selection and zone design. These regional differences matter when specifying components.

Property Layout and Zone Planning #

Zone planning divides the property into irrigation zones based on:

• Sun exposure (full sun areas need more water than shade)
• Plant types (turf irrigation differs from shrub beds)
• Slope (hillsides need slower application rates)
• Soil type (clay absorbs more slowly than sandy soil)

A 5,000-square-foot lot needs 3-4 zones. Larger properties or complex landscapes may need 6-8 zones. Each zone connects to the irrigation manifold and runs separately.

Utility Location and Permit Requirements #

Before any digging, the contractor marks utility lines or calls 811 to have them located. This includes gas, electric, cable, and existing irrigation if present.

Permit requirements vary by market, and we handle these differences daily across our service areas. In our Phoenix market, most residential irrigation installs don’t require permits.

In our Texas markets like DFW, San Antonio, and Houston, backflow preventer inspection is mandatory before the system goes live. Your scope should specify who handles permits and what inspections are included.

Core Components Included in Installation #

A complete irrigation system installation includes these components. If any are missing from a quote, ask why.

Sprinkler Heads and Nozzles #

Sprinkler heads fall into three categories:

Head Type	Throw Distance	Best Use	Typical Cost
Spray heads	4-15 feet	Small lawns, narrow strips	$3-8 each
Rotor heads	15-50 feet	Large turf areas	$15-35 each
Drip emitters	Point source	Shrub beds, trees	$0.50-2 each

Sprinkler head spacing follows the head-to-head rule: each head should throw water to the next head. A 15-foot spray head needs another head 15 feet away. Gaps in spacing mean dry spots.

Piping, Valves, and Manifolds #

Underground piping is Schedule 40 PVC for main lines and funny pipe (flexible tubing) for head connections.

The irrigation manifold houses all zone valves in one location. Each valve controls water flow to one zone. Manifolds should be installed in accessible boxes, not buried directly underground.

Control Panels and Smart Controllers #

The irrigation timer is the brain of the system. Basic timers cost $50-150. Smart controllers run $150-400 but offer the following:

• Weather-based scheduling
• Remote access via smartphone
• Water conservation through automatic adjustments
• Leak detection alerts

For rental properties, smart controllers prevent tenant over-watering and provide remote oversight. Property managers consistently approve these upgrades because the water savings and remote monitoring justify the upfront cost.

Backflow Prevention Devices #

Backflow preventers stop irrigation water from flowing backward into the drinking water supply. They’re required by code in most markets.

Common types include:

• Pressure vacuum breakers (most common residential)
• Double check valves (below-ground installation)
• Reduced pressure backflow assemblies (commercial irrigation)

Installation location and type depend on local code. Inspection may be required before the system goes live.

Installation Process: Step-by-Step Scope #

This is where most of the labor cost sits.

Trenching and Pipe Laying #

Trenching depth varies by climate. In Phoenix and Vegas, 6-8 inches is standard. In Denver or Seattle, 10-12 inches prevents freeze damage.

Trenches follow the zone plan, routing pipe from the water source to each zone location. Main lines run from the manifold to zone valve locations. Lateral lines branch off to individual heads.

Trenching methods include:

• Manual trenching (small properties, tight spaces)
• Vibratory plow (faster, less surface damage)
• Trencher machine (larger properties)

After pipes are laid, the crew backfills and compacts trenches. Surface damage should be minimal with proper technique.

Head Installation and Zone Configuration #

Installers set each sprinkler head at the correct height and angle for optimal coverage. Spray heads sit 1/4 inch above grade when retracted. Rotor heads may sit slightly higher.

Zone configuration connects each head to its valve. This is where the irrigation design becomes reality. Each zone should water similar plant types at similar sun exposures.

System Testing and Calibration #

Testing happens before any trenches are closed. Each zone runs while the installer checks:

• Head operation (pop-up, rotation, spray pattern)
• Coverage overlap
• Pressure at each head
• Flow rate through each zone

Calibration adjusts run times based on soil absorption rates and plant water needs. A calibrated system applies water slowly enough to soak in without runoff.

Documentation and Completion Standards #

Documentation separates professional installation from “some guy buried pipes in your yard.” Here’s what you should receive.

Photo Documentation of Completed Work #

Before any invoice, you should receive same-day completion photos showing the following:

• Manifold and valve installation
• Controller mounting and wiring
• Backflow preventer installation
• Representative coverage shots of each zone running

This matters for lawn and landscaping maintenance because future crews can reference what’s actually in the ground.

System Maps and Zone Diagrams #

A zone diagram shows:

• Location of manifold and valves
• Routing of main and lateral lines
• Zone boundaries with head counts
• Controller zone assignments

This document is critical when something needs repair. Without it, diagnosing a zone failure means guessing.

Warranty and Maintenance Documentation #

Professional installation includes warranty documentation covering:

• Parts warranty (manufacturer, 1-5 years)
• Labor warranty (installer, 1 year)
• What voids warranty (usually tampering or freeze damage from improper winterization)

Maintenance requirements should be spelled out. Most systems need seasonal adjustments, annual inspections, and winterization in freeze-prone markets.

Timeline Expectations for Professional Installation #

One common misconception: irrigation installation is a same-day job. For most single-family properties, it’s not.

Quote Turnaround #

Getting a quote shouldn’t take a week. We provide quotes within 48 hours of receiving the work order. The quote includes a detailed scope, itemized components, and a timeline estimate.

If a company takes 10 days to send a quote, imagine how long it’ll take to finish the job.

Installation Completion Windows #

For a 5,000-8,000 square foot single-family lot with 4-6 zones, expect the following:

• Site assessment: 1-2 hours
• Utility marking: 2-3 business days (waiting on locators)
• Installation: 1-2 days
• Testing and calibration: 2-4 hours

Total timeline from quote approval to completion: 5-7 business days in most cases. Larger properties or complex sites take longer. Our standard is 5-day job completion once work is approved.

Quality Verification Checklist #

How do you know the installation was done right? Use this checklist.

Coverage Testing #

Walk each zone while it runs. Look for:

• Dry spots between heads
• Over-spray onto hardscape
• Uneven spray patterns
• Misting (indicates too much pressure)

Coverage issues are easiest to fix before the installer leaves.

Pressure and Flow Verification #

Ask for PSI readings at the water source and at representative heads. A pressure drop of more than 10-15% from source to head indicates a problem.

Flow rate should match the design specs. If a zone was designed for 12 GPM and only delivers 8, heads won’t perform correctly.

Controller Programming Confirmation #

Review the programmed schedule before accepting the work. Check:

• Start times (early morning is best for water conservation)
• Run times per zone
• Watering days (match local water restrictions)
• Rain sensor function (if equipped)

Controller programming mistakes cause most early-stage complaints. Catch them at completion, not after the first water bill.

With verification complete, these common questions often arise.
