Our Services
At Southern Plumbing, we deliver reliable, high-quality plumbing solutions tailored to both residential and commercial needs across the Hobart region. Backed by 57 years of industry experience, our team brings deep expertise and innovative thinking to every project.
Underground Service Locating
We specialise in professional underground service locating using advanced technology to accurately detect and trace subsurface plumbing infrastructure including fire mains, domestic mains water supply, sewer lines and stormwater drainage systems. Our investigations support regulatory compliance in planning, enable safe excavation practices, and ensure construction or maintenance works are carried out without damaging existing infrastructure.
CCTV Drain & Pipe Inspections
We provide CCTV inspections of mains water, sewer, and stormwater drains to accurately assess the condition of underground plumbing infrastructure. Our high-resolution camera technology identifies blockages, structural damage, root intrusion, pipe conditions, misaligned joints, and other defects, providing clear diagnostics to support repairs, maintenance, and compliance reporting.
Leak & Odour Detection
We specialise in leak and odour detection services using advanced, non-invasive methods to identify hidden plumbing issues. Our electro-acoustic equipment pinpoints concealed and pressurised water leaks in walls, floors, and underground pipes, while non-toxic smoke testing traces odours, leaks, and cross-connections in drainage, sewer, and stormwater systems. These techniques help detect problems early and prevent costly damage.
Water Pressure & Flow Testing
We offer comprehensive water pressure and flow testing to diagnose performance issues in your plumbing system. Using pressure tests, flow checks, and isolation testing, we accurately detect inconsistencies, pinpoint faults, and identify areas of reduced performance. Whether you're experiencing low water pressure, irregular flow, or system imbalance, our testing helps ensure your plumbing operates efficiently and reliably.
Trade Waste Investigations
We deliver expert trade waste investigations to help businesses assess their systems, maintain performance, and meet local authority compliance requirements. Our services cover inspection and assessment of pre-treatment systems, including grease traps, oil-water separators, and paint settling tanks, along with flow monitoring, sampling, and detailed reporting, ensuring your trade waste systems operate safely and efficiently.
Detailed Diagnostic Reports
Our plumbing investigation and diagnostic reports provide clear, professional insights into the condition of your plumbing systems. Each report includes detailed findings, expert recommendations, and supporting imagery for full transparency and practical solutions. With accurate diagnostics and actionable advice, we we help you make informed decisions, avoid costly disruptions, and keep your systems performing at their best.
