Sewer-line repair, replacement and installation in Johannesburg and Pretoria

Slow drains, bad smells, and damp patches are rarely “nothing”—they're often early warnings of a sewer line problem. Left unchecked, a minor blockage or root intrusion can turn into a full failure, causing stubborn clogs, cracked pipes, and sewage surfacing in the garden or backing up inside the home. The frustration is that you can’t always pinpoint the cause, because most sewer lines are underground.

A sewage backup is overwhelming — and it’s a serious health risk. Alpha Plumbing has helped households across Johannesburg, Pretoria, and surrounding suburbs for over 35 years with sewer repair, replacement, and maintenance. Our PIRB-registered team is available 24/7 for emergency plumbing support, and we don’t charge extra after hours — you pay the same fee day or night. Call us on 010 001 8364

We start with the least invasive solution first. If it’s a simple blockage, we may clear it using rodding. If there’s stubborn build-up or root intrusion, we can jet blast the line to restore flow.

When the cause isn’t obvious—or when you've had repeated failures— we recommend a CCTV drain camera inspection. It shows what’s happening inside the pipe, helps us pinpoint the fault without guesswork, and keeps excavation targeted (only where necessary). Based on the findings, we’ll advise the best solution: sectional repair, rerouting, or a new sewer segment.

The Plumbing Industry Registration Board (PIRB) is a professional body for plumbers in South Africa, focused on improving accountability and protecting health and safety by promoting the integrity of water supply and wastewater systems.

Relevant guidelines:

• South African law requires that sewer work be carried out according to the South African National Standards (SANS 10400-P) by a qualified and registered professional plumber.
• The SANS 10400-P forms part of the National Building Regulations and governs the design, materials and installation of sanitary drainage systems in South Africa.
• The CSIR’s Technical Guidelines for Sanitation Systems outline recommended minimum sewer gradients and minimum depth/cover
• SABS-approved materials are essential to ensure long-term system performance, warranty integrity, public and environmental safety

Choosing a PIRB-registered plumber helps you avoid shortcuts and costly rework. Here’s what you’re really paying for:

Don't just settle for someone who can “clear a blockage” or even attempt DIY repairs. Non-compliance carries a structural and environmental risk; it could increase damage, void homeowners' insurance, or even have legal implications.

A PIRB-registered plumber can diagnose the root cause and repair or install sewer infrastructure in a way that’s designed to last, with accountability behind the work.

This ensures correct pipe gradients, enough rodding eyes (access points) and environmentally safe materials – saving you from costly repairs down the line and protecting your soil from harmful chemicals.

Before major sewer work, a CCTV inspection helps prevent misdiagnosis, overspending, and missed faults.

Putting the pipe in the ground is only half the job—it must be bedded correctly, set at the right depth, and covered with suitable soil so that the pipes are not vulnerable to traffic, building loads, or ground movement.

Choose durable, SABS-approved materials and demand SANS-compliant installation. (For rural, eco-conscious or off-grid builds, call us on 010 001 8364 for information on how Bio-Mite systems offer a smart alternative to those that link to municipal systems.)
