If your Calgary irrigation system makes a loud banging, thudding, or chattering noise when zones start or stop, you have a water hammer or pressure surge problem. Left unaddressed, these pressure spikes can damage valves, pipe connections, and head bodies over multiple seasons. J.G. Irrigation diagnoses and fixes irrigation noise problems across Calgary.
Calgary Irrigation Noise Problems — Diagnosis Guide
| Noise Type | Likely Cause | Fix |
|---|---|---|
| Loud BANG when zone starts | Water hammer — high pressure surge hits closed valve suddenly | Slow-close valves or water hammer arrestor — $80-$200 installed |
| Chattering/rattling during zone run | Loose valve diaphragm or head that vibrates at operating pressure | Valve diaphragm rebuild or head replacement — $60-$150 |
| Hissing from valve box | Minor valve body leak — air/water escaping past seal | Valve seal replacement or full valve replacement — $100-$180 |
| Humming from controller area | Solenoid coil buzzing — normal at 24V AC, but louder means aging solenoid | Monitor; replace solenoid if zone performance drops — $50-$80 |
| Pipe knocking underground when system on | Water hammer in lateral pipe — improperly secured pipe | Pressure reduction + arrestor installation — $120-$250 |
Water hammer in Calgary irrigation systems is more common than many homeowners realize — Calgary's municipal water is delivered at 55-75 PSI, and solenoid valves that open suddenly create significant pressure surges.
