Technical Data
Plastic sewer pipes have been used all over the world. Their contribution to public health and sanitation is excellent and they have out performed traditional material.
PP Inspection Chambers
Preformed Plastic Inspection Chambers have been widely used in Europe and the United States for the past forty years. The Chezy PP Inspection Chambers are described as having excellent structural integrity, good design and operational performance, water tightness and exceptional resistance to chemicals.
Performance
The Chezy PP Inspection Chamber is light weight and more economical than the traditional brick chamber, while its functional performance is described as excellent.
Load factors on chambers vary according to soil type, compaction during installation and groundwater. An important function of the chamber is to resist these factors and maintain the hole in the ground.
Advantages of the Chezy PP Inspection Chamber Over the Traditional Chamber
Chezy PP Inspection Chamber
- High compressive strength and fully functional even with 2 inches (50 mm) of ground settlement or flooding.
- 100% water and air tight connections, completely leak proof.
- Long life, very chemical resistant, no effect on chamber by H₂S or sewage.
- Very smooth inner walls, with no breeding of cockroaches or vermin.
- Very little labour required (80% less) — very economical.
- Aesthetically pleasing, with a very strong UV stabilized locked-down cover.
Traditional Brick Chamber
- Chamber can collapse and crack with ground settlement or flooding.
- Potential leaking chamber and leaking pipe connections where different materials are bonded by cement only.
- Corrosion of chamber by H₂S may attack chamber walls and lead to eventual collapse.
- Rough inner walls can become a breeding ground for cockroaches and vermin.
- Very labour intensive — expensive.
- Cast iron covers may rust, crack over time and can be susceptible to theft.

Inspection Chamber Assembly & Components
The chamber is presented as a simple push-fit assembly that provides easy access to the drainage system for maintenance, inspection, rodding and debris removal.
Designed for Faster, Flexible Installation
Our 315 mm PP Inspection Chambers allow easy access to the drainage system and are described as a less labour-intensive and more economical alternative to traditional construction methods.
The chamber connections are flexible and allow a deflection of pipe of 3° in all directions. The catalogue states that the chamber will not leak even with ground settlement of 50 mm (2 inches).
The PP Inspection Chambers allow for 5 incoming pipes and one outlet. Connections not used can be sealed by the plugs provided.
Flexible Bend
Flexible bend for PP Inspection Chambers allows easy adjustment of pipe alignment and angles from 0°–180°, ensuring a smooth and secure connection during installation.

Cover Load Strength
The UV stabilized Chezy collar and cover have been tested for their load strength. A 5 mm bead of silicone is to be applied between the cover and collar for an air and water tight connection.
| Item | Load (kg) |
|---|---|
| Medium Duty | 300 |
| Heavy Duty | 1,500 |
Adaptors for Jointing
Various adaptors can be used for jointing the Chezy PP Inspection Chamber to different types of incoming and outgoing pipes, including VCP, HDPE twin-wall corrugated and uPVC pipes.
