Assessment & Code Compliance Check
1-2 hoursPlumber inspects existing plumbing: supply pipe type (lead, galvanized, copper, PEX, polybutylene, Kitec), DWV layout, venting, water pressure (should be 40-80 psi), and drain flow. Identifies code violations: missing vents, undersized drains, cross-connections, improper trap configurations. Checks if backwater valve is required (Toronto Chapter 681).
Permit Application
1-3 days processingPlumber pulls municipal plumbing permit for rough-in work (new fixtures, repiping, backwater valves, gas lines). Permit costs $150-$500 depending on scope. Simple fixture swaps (toilet, faucet) don't need permits. Gas work requires separate TSSA permit and pressure test.
Material Procurement & Scheduling
1-3 daysPlumber orders pipe, fittings, fixtures, valves. PEX supply is standard for repiping (flexible, freeze-resistant). ABS or PVC for DWV (ABS is black, PVC is white — both code-approved in Ontario). Schedules coordination with electrician (water heater), HVAC (boiler), or drywall if walls need opening.
Rough-In & Execution
Varies by scopePlumber shuts water at main valve, drains lines, removes old pipe. Installs new supply lines (PEX manifold system or trunk-and-branch), drains (gravity slope 1/4" per foot minimum), and vents (every fixture needs air path to roof). Pressure-tests supply at 100 psi for leaks. Backwater valve installs require breaking basement floor and sewer tie-in.
Inspection & Final Connection
Inspection: 30-60 minMunicipal inspector verifies code compliance: proper venting, drain sizing per fixture unit loads, trap configurations, backflow prevention, gas line pressure test (TSSA). Pass = approval to close walls and connect fixtures. Plumber installs fixtures, tests all drains and supply lines, adjusts water pressure if needed.

Money-Saving Tips
Install a backwater valve — many GTA cities offer $1,000-$2,500 rebates and it prevents sewer backup.
Switch from rental water heater to owned — rental fees add up to $6,000-$10,000 over the equipment lifetime.
Rough-in all plumbing before closing basement walls — adding a bathroom later costs 2-3x more.
PEX costs 30-40% less than copper and is faster to install — use it for supply lines.
Camera inspect your sewer before buying an older home — $300 can save you from a $15,000 surprise.
