The Problem Traditional pipe stoppers are difficult to install. • The seal refuses to grip, • Wing nut is not easy to tighten • Screw threads seize up Installation can take many minutes inside a manhole or inspection chamber. Retrieval involves facing a live wall of sewage when the stopper is unscrewed.
ASP’s design team have considered the issues facing the operator and developed a new patented design, creating a stopper that will seal quickly and effectively in a matter of seconds! The secret of success is in the inventive cam lever and new stabilising heel. The new Camstopper will change the way that stoppers are used, bringing the drain stopper into the 21st century.
Camstoppers - Application
The Camstopper retains the benefits of the traditional design of discs and a rubber seal, but the application of force is now through a lever actuation. This allows the seal to be made quickly, easily and accurately. The seal is also consistent as the lever pressure is applied to a pre-determined load.
Camstoppers - Removal
The exceptional simplicity of retrieving the Camstopper is such that the operator does not have to enter the manhole or chamber to collect it.
Tying a rope around the cam handle allows it to be removed remotely, with no risk of operator contamination or soaking! It is pulled away from the invert and out of the chamber in seconds.
Camstoppers - Health & Safety
For the first time ever, this ‘non man-entry’ retrieval technique allows operators to comply with the Confined Spaces Regulations 1997* which requires the employer to:-
“Avoid entry into confined space if possible by using mechanical means or undertaking the work from outside the confined space”.
Using the new Camstopper both employer and user have the opportunity and responsibility to comply with these published regulations governing access into manholes, inspection chambers and other confined spaces.
Camstoppers - Wire & Water Testing
The new Camstopper is designed to allow standard air and water testing and retains the conventional 1/2” bsp thread to connect testing kits.
