Frequently Asked Questions

Why do results differ between the old app and this tool?

Both the legacy Bucket test app and catchcan.co.nz use the same base maths. Irrigation testing is a snapshot in time, so variations in site conditions or system wear can affect results. Ensure the catchcan.co.nz instructions are followed and consult your irrigation partners for guidance on improving system outcomes.

Does IrrigationNZ or SCADAfarm complete on-site Catch Can tests?

No, IrrigationNZ promotes efficient water use but doesn't conduct field tests. SCADAfarm supports tool outcomes but does not complete field tests. For field testing, contact your irrigation company or refer to accredited assessors on the IrrigationNZ website.

I failed my Catch Can test — can you help me fix it?

The tool provides a platform for completing tests and standardised reporting to support operations and compliance. We do not provide in-field assessments or product support. If you're concerned about your test results, send your report and field data to [email protected] with the subject "catch can query." Our support is focused on the tool, not field system fixes. Irrigation NZ offers a list of accredited assessors and Irrigation providers for further assistance.

How do I update my irrigator after changes to my pivot (e.g., length, flow rate, sprinkler type)?

At this stage, the best option is to create a new irrigator profile. Editing or deleting irrigators is not supported. Use logical naming (e.g., serial number and update date) to track changes.
