Using Chambers At A Change Of Direction (Video)

When installing a drainage system, many wonder if an inspection chamber can change the direction of the main drain run. This article clarifies its correct use and provides essential tips.

What Are Inspection Chambers Used For?

Inspection chambers provide access for cleaning and maintenance. They are not meant for altering the main drain’s direction but for integrating additional pipes into the main run.

How to Change Direction on a Main Drain Run

1. Using the Main Channel Correctly

• Always position one end as the inlet and the other as the outlet.

• This setup creates a longer bend, allowing adjustments through pipe fittings and maintaining a consistent gradient.

2. Avoiding Tight Bends

• Side branches are for additional pipes, not directional changes.

• Using them for turns results in tight bends, making maintenance difficult.

3. Creating a 90 Degree Turn Correctly

• Set the main run to pass through the chamber at 45 degrees.

• Use a 45-degree inlet and 45-degree outlet to create a smooth, sweeping turn for better flow and maintenance.

Benefits of Proper Setup

• Better Flow: Gradual turns prevent debris buildup.

• Easier Maintenance: Long bends simplify inspections.

• Regulatory Compliance: Ensures adherence to building codes.

Use inspection chambers for access and pipe integration, not directional changes. For turns, use long sweeping bends with proper fittings. Watch our video for a visual guide.
