When Do You Need a Plumbing Inspection?

In Queensland, council plumbing inspections are required for most notifiable work before you can lodge your Form 7 Compliance Certificate. The inspection confirms that your installation meets AS/NZS 3500 standards and complies with the Queensland Plumbing Code.

Common jobs that require inspection include:

• New sewer and drainage connections
• Stormwater drainage installations
• New water service connections
• Greywater treatment systems
• On-site sewerage facilities
• Fire service installations

How the Inspection Booking Process Works

Each council in Queensland has its own booking system, but the general process is:

1. Complete the work to inspection stage — leave trenches open, pipes visible, connections accessible
2. Book the inspection — online portal, phone, or via TradeDesk
3. Provide job details — address, lot/plan number, type of work, your QBCC licence number
4. Wait for confirmation — most councils book within 2-5 business days
5. Be on site — you or your nominee must be present during inspection
6. Pass or fail — if passed, you can backfill and lodge Form 7. If failed, rectify and rebook.

What Inspectors Look For

Council plumbing inspectors check your work against AS/NZS 3500 requirements. Key things they verify:

• Correct pipe grades — minimum 1:60 fall for 100mm drainage, 1:40 for 65mm
• Proper jointing — solvent cement joints, rubber ring joints correctly seated
• Vent sizing and placement — adequate venting to prevent trap seal loss
• Backflow prevention — correct devices installed where required
• Clearances — minimum distances from boundaries, structures, and other services
• Materials compliance — WaterMark certified products used throughout
• Trench depth and bedding — adequate cover and correct bedding material

Common Reasons for Inspection Failure

• Insufficient fall on drainage pipes (most common)
• Missing or incorrect vent configuration
• Non-WaterMark products used
• Trenches backfilled before inspection (instant fail — must re-excavate)
• Plumber not present on site
• Work doesn't match the application/plan

How TradeDesk Automates Inspection Booking

TradeDesk integrates with council booking systems so you can request inspections directly from the app:

• One-tap booking — select the job, choose inspection type, submit
• Auto-fills your details — QBCC number, address, lot/plan from the job record
• Calendar sync — inspection date added to your schedule automatically
• Reminders — alerts before inspection so you don't forget to be on site
• Pass/fail tracking — record the result and trigger Form 7 generation on pass

Tips for Passing First Time

1. Never backfill before inspection — this is the #1 mistake that costs plumbers time and money
2. Take photos before booking — if there's a delay, you have evidence of the work at inspection stage
3. Check your grades with a level — don't eyeball it; inspectors use laser levels
4. Have your plans on site — inspectors compare work to the approved plan
5. Use TradeDesk's compliance checker — AI verifies your work meets AS/NZS 3500 before the inspector arrives
