🚧 What You Need to Know About Sewer Stack Works — Avoid Costly Building Plumbing Issues
If you live or work in a multi-storey building, chances are your property relies on sewer stacks — the vertical piping systems that carry waste from your sinks, toilets, and showers down through each level of the building.
At Sidco Plumbing Solutions, we’re experts in inspecting, repairing, and replacing these crucial systems across Sydney and the Illawarra. Whether you’re managing a commercial complex or a residential apartment block, our licensed team has the tools and know-how to get it right.
🧰 What Is a Sewer Stack?
A sewer stack (also called a soil stack or drain stack) is a large vertical pipe that carries wastewater and sewage down through a building and out to the main sewer line. It connects to smaller horizontal pipes from each unit or floor.
Proper sewer stack function is essential for:
- Safe and sanitary waste removal
- Preventing backflow or odours
- Maintaining water pressure and flow in multi-storey plumbing
🛑 Signs You Might Need Sewer Stack Repairs or Replacement
Sewer stacks aren’t meant to last forever. Depending on material and usage, they often deteriorate after 30–50 years. Common signs of problems include:
🚽 Frequent drain blockages on upper levels
💧 Leaks or water stains behind walls or ceilings
🌬️ Unpleasant odours or sewer smells in apartments
💥 Pipe corrosion or visible cracks
💦 Gurgling noises or slow drainage on multiple levels
Ignoring these signs can lead to major damage and health hazards — especially in older buildings.
