What does a Calgary irrigation inspection include?

A Calgary irrigation inspection by J and G Irrigation includes zone-by-zone coverage assessment checking every head for correct arc, radius, and pop-up function, pressure measurement at the main connection and at zone heads, backflow preventer physical assessment and City registration status check, controller programming review against current Calgary watering need, zone wire continuity testing, and rain sensor function verification. A written report is provided for full diagnostic inspections.

How often should a Calgary irrigation system be inspected?

A Calgary irrigation system should receive at minimum an annual spring startup inspection that includes zone-by-zone head checks. Systems over 7 years old should receive a full diagnostic inspection every 2 to 3 years to check pressure, flow, wiring, and backflow performance. Post-hail assessment is recommended within 1 week of any significant hail event in Calgary, as June through August hail is a common cause of popup head damage.

Can J and G Irrigation inspect a system they did not install?

Yes. J and G Irrigation inspects and services irrigation systems regardless of original installer or brand. A full diagnostic inspection on a previously unknown system includes documentation of the zone layout, head types, valve locations, and controller programming, resulting in a complete written record that can be used for ongoing maintenance reference and for any future repair or upgrade work.

How much does sprinkler winterization cost in Calgary?

Professional sprinkler winterization in Calgary costs $80 to $150 for most residential systems depending on the number of zones. J.G. Irrigation offers flat-rate pricing with no surprise fees. Call 587-433-4795 for an exact quote.

When should I winterize my sprinklers in Calgary?

Calgary sprinkler systems should be winterized before the first hard freeze, typically between late September and mid-October. Booking by September is recommended as appointment slots fill up quickly. A hard freeze (below -4°C overnight) can crack irrigation pipes within hours.

What happens if you don't winterize your sprinklers in Calgary?

Skipping winterization in Calgary can result in cracked pipes, burst valves, broken backflow preventers, and damaged sprinkler heads from ice expansion. Repair costs from freeze damage typically run $300 to $1,500 or more — far exceeding the cost of a professional blowout.

Can I winterize my own sprinkler system?

DIY sprinkler blowouts require a compressor rated at 20+ CFM at 50 PSI and precise knowledge of your zone layout. Improper technique can damage head diaphragms, crack PVC fittings, or leave water in low spots that will freeze. Most Calgary homeowners find professional blowout service the safer and more reliable option.

When should I turn on my sprinklers in Calgary in spring?

The safe window to activate your Calgary sprinkler system is mid-May to early June, once overnight temperatures are consistently above 0°C and the ground has fully thawed to at least 6 inches deep. Activating too early risks pipe damage from ground frost.

What does a spring sprinkler startup include in Calgary?

A professional spring startup includes slowly opening the main water supply valve, pressurizing each zone, inspecting every sprinkler head for damage, adjusting head rotation and arc, checking the backflow preventer, testing the controller schedule, and confirming full coverage across all zones.

How do I know if my sprinkler system has a leak?

Common signs of a Calgary sprinkler leak include soggy or waterlogged patches on your lawn, a sudden spike in your water bill, uneven watering across zones, sprinkler heads that stay up after the system shuts off, unusually green stripes in the grass, and soft or sinking spots in the yard.

How fast can J.G. Irrigation fix a broken sprinkler system?

J.G. Irrigation offers same-week sprinkler repair service across Calgary. Most residential repairs — broken heads, leaking valves, stuck pop-ups — are completed in 1 to 3 hours. Call 587-433-4795 or book online for priority scheduling.

How much does sprinkler repair cost in Calgary?

Sprinkler repair in Calgary typically costs $75 to $250 for common issues like broken heads, stuck pop-ups, or clogged nozzles. Valve replacements run $100 to $300. Underground pipe repairs depend on depth and length but usually fall between $200 and $600 for residential systems.

Calgary Irrigation System Inspection: What Is Checked and When to Book

What Is a Calgary Irrigation System Inspection?

An irrigation system inspection in Calgary is a diagnostic service where a licensed irrigation technician assesses the full system — every zone, every head, the backflow preventer, the controller, and the main connection — and documents what is working correctly, what needs adjustment, and what requires repair. An inspection is different from a spring startup or a repair call: it is a systematic assessment designed to catch developing problems before they become expensive failures.

What J&G Irrigation Checks During a Calgary Irrigation Inspection

Zone-by-Zone Performance Assessment

Coverage radius of every head vs design specification

Spray arc on rotor heads vs original setting

Head pop-up and retraction speed (slow retraction = weak spring = water on surface after zone shuts off)

Misting from spray heads (indicates pressure too high)

Matched precipitation rate within each zone (spray + rotor mixing is a common design error)

Coverage overlap between adjacent zones (1/3 overlap is the standard; less leaves dry strips)

Pressure and Flow Assessment

Static pressure at the main connection compared to design specification

Dynamic pressure loss between mainline and outermost head (indicates undersized pipe or a developing leak)

Flow rate comparison across zones (a zone running significantly low flow vs design indicates a mainline breach)

Backflow Preventer Assessment

Physical condition of housing, bonnet, and test cocks

Drip or weeping from relief ports (indicates internal failure)

Test cock function (stuck = last tester forced it; free = good)

City registration status — is the annual test filed and current?

Controller and Wiring Assessment

Controller programming vs actual Calgary watering need (oversized summer schedule left running in September is extremely common)

Zone wire continuity test (identifies broken or shorted wires from freeze-thaw or dig damage)

Smart controller weather-data connection status

Rain sensor function (legally required by City of Calgary on all systems)
