Chezy PP Inspection Chambers

Our 315 mm PP Inspection Chambers allow for easy access to the drainage system for maintenance, inspection, rodding and the removal of debris. Chezy Preformed Plastic Inspection Chambers are a simple push-fit assembly and have been designed to offer less labour intensive and more economical alternatives to traditional construction methods.

The connections to the Chezy PP Inspection Chamber are flexible and allow for a deflection of pipe of 3° in all directions. Our chamber will not leak even if there is ground settlement of 50 mm (2 inches).

Our PP Inspection Chambers allow for 5 incoming pipes and one outlet. Connections not used can be sealed by plugs provided.

The chamber base is available for both 110 mm and 160 mm drainage layouts, with branch inlets designed to optimize flow directions. Chezy PP Inspection Chambers come with either side or bottom outlets and can be joined to uPVC or vitrified clay (VC) pipes (160 mm). The 150 mm central channel in the chamber base is designed with a built-in fall for good flow performance.

This section incoporates one inlet and one outlet (inlet of 110 mm or 160 mm and outlets of 160 mm for uPVC pipes or 180 mm for VC pipes).

This section of the PP Inspection Chamber is joined to the base by a simple dry jointing method (rubber ring), providing an instant water tight joint. It has four 110 mm inlets (45° to the central channel) and the whole body can be rotated about the base, so that the directions of the inlets can be shifted to the direction where most of the incoming pipes are. This results in savings in the number of fittings used. Push fit jointing using rubber rings is done between the uPVC pipes and the PP Inspection Chamber.

The chamber riser pieces are designed for dry jointing and have strengthening ribs for additional structural strength and for bonding with the back-fill.

The riser pieces can be simply built up to the required height between the chamber base and cover by secure push fit sealing rings for water tight joints. The Chezy riser pieces have strengths in access of 0.7 KN/m2.

The Chezy PP Inspection Chamber frame and cover is made of high impact and UV stabilized ABS. It has been tested to BS EN 1253-4 for watertightness, odour tightness and backflow tightness. It has been awarded a Class BT.

The Chezy chamber complies to application area code U (outside the building structure) and application area code D (within the building structure), hence the classification UD for our chambers.

The frame fits onto the outside of the riser and is sealed by a water tight rubber seal. The matt finished cover (for anti slip) is screwed down in the frame for security and reduced risk of unwanted removal. The UV stabilized Chezy frame and cover have been tested for their load strength.
