What to know
Pre-approval is programme-specific.
Markham’s current programme requires technical review and approval before new work. Other programmes may not use the same pre-approval model.
Project context
Permits authorize the regulated installation scope.
The municipality may require drawings, contractor information, fees and site inspection. Permit approval is not a flood-free guarantee or programme payment.
Owner handover
Inspection occurs before concealment.
Coordinate the installer, inspector and restoration sequence so the valve and connections remain visible when required.
Project checklist
Keep the decision specific to the property.
Use the assessment, authority requirements and written scope rather than choosing from a generic product package.
- Technical review where required
- Building or plumbing permit
- Licensed-contractor requirement
- Pre-concealment inspection
- Final application sequence
