Irrigation

Moving water efficiently from a supply connection to crops, lawns, or garden beds requires matching pipe sizes, zone valves, and emitters to site pressure. Coburn Supply carries irrigation supplies for residential yards, commercial grounds, and agricultural fields. Our inventory includes underground PVC piping, flexible tubing, solenoid control valves, zone manifolds, and backflow preventers for building or repairing irrigation systems. Equipment specs vary by application. A home garden irrigation system uses smaller supply lines and targeted drip tubing to water specific plants without waste. Larger irrigation systems for farms require heavy-duty mainlines, high-volume rotors, and high-capacity valves to manage continuous flow across wider acreage.

When you are ready to buy irrigation supplies, order online or visit a Coburn Supply counter to confirm hardware compatibility before installation.


  • Irrigation System Components
    Sprinkler heads, control valves, drip line, and PVC or poly pipe make up the core parts stocked in this category, covering both spray and drip-based watering methods.
  • Buy Individually or by the Zone
    Replace a single valve or sprinkler head, or order enough pipe and fittings to build out a full zone; ask your Coburn rep about pricing on larger material orders.
  • Sized for Yards and for Acreage
    Smaller-diameter parts suit a home garden irrigation system, while heavier pipe, backflow devices, and larger valves cover the ground that field and pasture watering demands.
  • Matched to Your Water Source
    Parts are stocked for wells, municipal water, and pond or canal draws, so new equipment can be matched to the water source already on site.
  • Parts to Keep Systems Running
    Replacement heads, valve diaphragms, and fitting repair parts are available for systems already in the ground, so a single broken part doesn't mean digging up an entire zone.

How It Works / Where to Use

  • Irrigation Supplies by Application
    Sorting parts by where they're used helps narrow down the right components for a given watering setup.
  • Lawn and Turf
    Pop-up spray heads, rotor heads, and zone valves sized for residential lawns and turf areas.
  • Garden and Landscape Beds
    Drip line, emitters, and micro-spray parts for garden watering systems built around individual plants or rows.
  • Farm and Field
    Mainline pipe, gate valves, and larger-capacity fittings sized for row crops or open pasture.

Key Field Specifications & Planning Steps

Review pipe sizing, water source, and zone layout before ordering parts, since mismatched components are a common cause of pressure and coverage problems.

  • Pipe Size and Material
    Confirm whether the existing system uses PVC, polyethene, or another pipe material, and match new fittings to the corresponding diameter.
  • Water Pressure and Flow Rate
    Check available PSI and GPM at the source, since sprinkler head and valve selection both depend on these numbers.
  • Zone Count and Layout
    Map out how many zones the property needs based on plant type, sun exposure, and slope before buying valves and controllers.
  • Controller Compatibility
    Confirm that new valves and sensors will wire into the existing controller, or budget for a controller upgrade at the same time.

Frequently Asked Questions 

What are irrigation supplies?
Irrigation supplies are the sprinklers, valves, pipe, and fittings used to build and repair a watering system for lawns, gardens, or farmland.

Where to buy irrigation supplies?
Coburn Supply is one of several irrigation equipment suppliers offering parts for both home garden irrigation systems and larger farm setups.

How does a farm irrigation system differ from a home setup?
Field and pasture systems typically run wider mainlines and higher flow rates than a home garden irrigation system built for a smaller yard

Do irrigation supplies work with existing sprinkler systems?
Most valves, heads, and fittings are sized to match common pipe standards, so they can be added to a system already in the ground.

Can I buy irrigation supplies for a single repair?
Yes, individual parts like valve diaphragms and sprinkler heads are stocked separately for one-off repairs, not just full system installs.
