This schedule specifies the requirements for the Camstopper® CAM range and the lockable CAMV® range of drain stoppers, as manufactured by NORHAM (France) and assembled by NORHAM Plastics Ltd (UK). The devices are designed for the temporary stopping of flows from domestic drains and small adoptable sewers made of clay and or plastic in sizes between 90mm to 160mm.
The Camstopper® range comprises a baseplate, top plate, and lever, manufactured from Fibreglass and Nylon, surrounded in an EDPM rubber seal. The Camstopper® range is designed to resist a hydraulic pressure between 0.3 and 0.5 bar.
The Remote Installation Device (RID) is an extendable pole with a socket to fit the lever of the Camstopper® and a mechanism to facilitate the operation of the Camstopper® lever from outside the chamber.
The CAMV® lockable stopper has an alternative lever that is only installable and removable using a RID pole with a clip that engages with the locking lever.
Full details can be found in the Assessment Schedule.
