RSM scope
Independent education and standards-informed practice guidance.
External authority
Law, code, municipal rules, permits, manufacturer instructions and qualified professional decisions remain controlling.
Project responsibility
Owners, designers, contractors, inspectors and authorities retain assigned duties.
Core principles
Build practice around clear decisions and verifiable outcomes.
Confirm local requirements
Permits, inspections, sewer arrangements and rebates vary.
Support informed decisions
Provide options, limitations, costs, maintenance and residual risk.
Leave maintainable records
Owners need access, labels, test instructions and close-out records.
Practice detail
Assessment and communication
Ask about prior events, insurance, renovation, fixtures, sump operation, outages and maintenance. Explain sewer backup, groundwater and overland flow. Avoid diagnosing hidden conditions without evidence.
Practice detail
Permits, programmes and scope
Rebates can fund eligible measures but do not prove suitability. Confirm official programme terms, pre-approval, permits, contractor requirements and inspection timing.
Practice detail
Handover and readiness
Show owners valves, pits, alarms, panels, barriers and records. Demonstrate safe routine checks and warning signs. Encourage annual review and updates after storms, renovation, purchase or occupancy change.
