Roots & watering
Uneven watering or dry bags
When one bag dries while its neighbour stays wet, start by comparing water delivery. Increasing irrigation everywhere can make the wet areas worse.

Why do irrigation lines knock when valves close?
Sudden pressure changes deserve an equipment review, especially after adding zones.

Why the root zone matters
Repeated hydraulic shocks may disturb consistent water delivery and damage connections serving coir crops.
01 / OBSERVE
Three checks before you change anything
- Record whether the noise coincides with pump or valve changes.
- Inspect visible leaks or movement without opening pressurised components.
- Ask the irrigation technician to assess valve timing, pressure control and pipe support.
02 / NARROW IT DOWN
When did it begin?
Choose the closest observation for a suggested next check.
After changing valves
Check compatibility and closing behaviour with the installer.
After increasing flow
Review the revised zone demand and pressure-transient protection.
It has always occurred
Include it in planned servicing rather than accepting repeated shocks as normal.
03 / TAKE THE NEXT STEP
Leave with something useful
Document the sequence that reproduces the noise for the technician.
Keep in mind
Do not loosen fittings on a live pressurised system to investigate the sound.
