Drainage Installation and Maintenance Experts

A blocked drain, overflowing sewer or failed stormwater system can bring your home or business to a halt fast.

That’s why drainage issues need attention from experienced professionals who understand how to diagnose problems accurately and fix them efficiently. For more than 50 years, B&B Plumbing has been providing specialist drainage services to residential, commercial and industrial sites across the Auckland area. Whether it’s sewer repairs, stormwater maintenance, cesspit cleaning or grease trap servicing, our team is equipped with industry-leading tools—and we’re available 24/7 for emergency callouts. When you need fast, reliable drainage solutions, we’re here to get the job done.

Sewer Repairs, Upgrades & Maintenance

Sewer issues are serious, often messy and always urgent. Blocked or damaged sewer lines can lead to bad smells, slow drains, overflowing toilets and health hazards. We use CCTV drain cameras to identify the exact cause of the problem—whether it’s tree roots, collapsed pipes, foreign objects or ageing infrastructure. Once identified, we clear blockages, repair pipes, upgrade lines or replace full sections of the system as needed.

With our hydro-jetting equipment, we can cut through roots, blast out debris and restore sewer flow without unnecessary excavation.

Stormwater Drainage & Flood Prevention

Stormwater systems protect your property from flooding during heavy rain. When blocked or poorly maintained, they can cause pooling, surface flooding and structural water damage. We maintain, repair and install stormwater drains, soak holes, channels, sump pits and downpipes. Our hydro-jet trucks efficiently remove silt, leaves and built-up debris from stormwater lines to keep water flowing freely. If you're building new or upgrading old infrastructure, we design and lay stormwater systems that meet all regional standards and are built to last.

Cesspit Cleaning & Maintenance

Cesspits require regular cleaning to prevent blockages, odours and overflow. We use high-powered vacuum trucks to remove sludge, silt and debris from cesspits of all sizes. Our team schedules recurring maintenance for commercial, industrial and high-use sites, ensuring compliance with council requirements and reducing the risk of flooding or system failure.

Grease Trap Cleaning & Servicing

Grease traps in commercial kitchens and food production sites need regular professional servicing to prevent blockages and backflow issues. We clean and maintain grease traps, remove accumulated fats and oils, and ensure your system is operating efficiently. Routine cleaning helps businesses stay compliant and prevents costly plumbing issues.

Drain Unblocking & Hydro Jetting

Hydro jetting is the most effective way to clear stubborn drain blockages. Our hydro jet trucks blast high-pressure water through pipes to break down debris, tree roots, grease buildup, silt and foreign objects. This method restores full flow without harming the inside of your pipes and is suitable for residential, commercial and industrial drainage systems.

CCTV Drain Inspections

Our CCTV cameras allow us to see inside your pipelines in real time. This technology eliminates guesswork and helps us quickly identify the cause and location of drainage issues. It’s the ideal tool for diagnosing recurring blockages, assessing the condition of old pipes, and planning new installations or repairs.

Drainage Design, Excavation & Installation

If you’re starting a new project or replacing ageing infrastructure, we provide full drainage system design and installation. Our services include:
