Metro Rod are on-hand 24/7/365 across the UK to offer a range of stack cleaning services

How Does the Soil Stack Pipe Work?

Every toilet, sink and bath is connected to a horizontal pipe known as a waste pipe. These horizontal pipes transport used water and waste away from a property by joining with a vertical pipe on the outside of the building known as a soil stack.

The soil stack pipe is the long vertical pipe that spans the full length of a building. The vent at the top of the soil stack pipe allows air to enter the pipe to help the water move, whilst also letting the gases exit the property to avoid smells.

The bottom end of the pipe goes underground through a manhole to connect to the main sewage system.

How Do Waste and Soil Stack Pipes Get Blocked?

Horizontal waste pipes often get blocked with non-flushable items, as well as fat, oil and grease. You’ll know when your soil stack is blocked when:

  • Toilets not emptying
  • Sinks or baths not draining


The vertical soil stack pipe can also become blocked with these items as well as build ups of uratic salt, narrowing the soil stack pipe. Blockages are typically worse at the bottom of a soil stack pipe.

These blockages can appear as:

  • Water bursting from the joints of the soil stack pipe
  • Overflowing dirty water from the bottom of the pipe

Blocked waste pipes or soil stacks can bring businesses to a halt and put properties at risk. Routine maintenance plans for soil stack cleaning can help avoid emergency callouts and costly reactive services being required.
