How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 60–150 minutes.

Ground level only.

Bring

• diverter kit sized to the downspout

3. 3. Fit the diverter per kit instructions and seal.

If it does not match the plan

• Downspout feeds from a roof needing access: ground-level work only, route roof work to a contractor
• Cistern is not the resident's own or the garden's shared equipment: STOP
• Material is asbestos-cement pipe: STOP, do not cut, report

What counts as done

• Diverter tee installed at chest height and sealed, no leaks on test pour
• Flush chamber sized to the roof area (sizing noted in proof)
• Before/after photos + GPS

Proof is measured against these, not judged by taste.
