The Sioux Chief Hydra-Rester Hangsell is a specialized water hammer arrestor designed to mitigate the effects of water hammer in plumbing systems. Water hammer occurs when a sudden change in water flow, such as quickly closing a valve, creates a pressure surge that can damage pipes and fixtures. The Hydra-Rester Hangsell absorbs this shock, protecting your plumbing infrastructure

The HydraRester ‘A’ size is ideal for installation on supply lines to washing machines, electronic and clockwork garden water timers, dishwashers and all general domestic and commercial appliances likely to cause water hammer.
