Calgary Irrigation Valve Repair and Replacement: Zone Valve Diagnosis
Irrigation zone valve failure is the most common Calgary sprinkler repair call J.G. Irrigation receives. Valves control each zone's on/off function — when they fail, a zone either won't activate or won't shut off. J.G. Irrigation's IA-certified technicians diagnose and repair zone valves on the same visit with a flat $90 diagnostic fee applied to any repair completed.
Zone Valve Failure: Diagnosis Guide
| Symptom | Likely Cause | Solution | Cost |
|---|---|---|---|
| Zone won't turn on | Solenoid failure or wiring break | Solenoid replacement or wire repair | $90-$180 |
| Zone won't shut off | Debris in valve diaphragm or torn diaphragm | Valve flush or diaphragm replacement | $90-$180 |
| Zone turns on randomly | Controller fault or valve wiring short | Wiring diagnosis and repair or controller replacement | $90-$280 |
| Water dripping from valve box | Valve body crack or fitting failure | Valve body replacement | $150-$250 |
| Low pressure on one zone only | Partially failing valve not opening fully | Valve rebuild or replacement | $90-$200 |
Valve Rebuild vs Full Replacement
Most Calgary zone valve failures are repairable at lower cost than full replacement. A solenoid replacement ($40-$80 part) restores a zone that won't activate; a diaphragm rebuild ($20-$50 part) fixes a zone that won't shut off. Full valve body replacement is warranted when the body shows cracking, corrosion, or freeze damage. J.G. Irrigation technicians carry rebuild kits and full replacement valves for Hunter, Rain Bird, and Weathermatic — the most common valve brands in Calgary systems — and make the recommendation at the $90 diagnostic visit.
Calgary Valve Replacement Brands
J.G. Irrigation replaces all zone valves with commercial-grade Hunter or Rain Bird valves — the same brands used in new installations. We do not install economy-grade valves as replacements. All valve replacements carry J.G. Irrigation's 2-year parts and labour warranty.
