Use the live rear camera with the selected valve’s simulated pipe overlay.
Live camera requires browser permission. A captured photo works as a reliable fallback.
Drag the pipe overlay to line it up with the ground.

Estimated feature distance

Distance = wave speed × return time ÷ 2| Observed reflection | Typical interpretation | Confidence |
|---|---|---|
| Same-sign, strong | Closed end, closed valve, major restriction | Qualitative |
| Opposite-sign, strong | Open end, reservoir-like boundary, major leak | Qualitative |
| Smaller multi-peak | Tee, branch, multiple fittings, overlapping returns | Test required |
| Broadened / attenuated | Flexible pipe, viscoelastic damping, air, long run | Test required |
| Unexpected early return | Unmapped fitting, size change, nearby restriction | Test required |
Important: Published transient research supports using reflected pressure waves for leak and feature detection, but it does not provide a universal ready-made waveform chart for every landscape-irrigation fitting. Pipe material, diameter, wall thickness, restraint, pressure, flow, temperature, sensor bandwidth and pulse shape all change the trace.
Published leak datasets
Published datasetExternal labeled signals available for cross-reference and validation.
Mendeley: Experimental Testbed Water Distribution SystemDOI 10.17632/tbrnp6vrnj.1 · 280 labeled 30-second signals from a 47 m, 152.4 mm PVC testbed.

| Circumferential crack | CC | Published comparison class |

Recorded variables: looped or branched network; multiple background-flow conditions; with/without background noise; two accelerometers, two hydrophones, and two dynamic-pressure sensors. Accelerometer and pressure files are CSV; hydrophone signals are RAW.
Validation rule: these signals are not treated as a universal landscape-irrigation fingerprint. They are a published comparison set. IVy results should show the source tier beside every match.
