Piston Type-Lead Free Copper Alloy Plumbing Products

The banging noise in the pipes is caused due to the shocks from the water which is flowing at high speed inside the piping systems when any fixture gets closed suddenly. The sudden stoppage of the water which is a non-compressible liquid that is flowing at a provided pressure and velocity creates a spike or surge of water and is known as a water hammer. Whenever this happens, a wave of pressure travels back via the pipe unless it can find out a relief point. The Piston Type-Lead Free Copper Alloy Plumbing Water Hammer Arrestors have been designed for eliminating this effect. They are lead-free in construction which complies with the requirements of Lead-Free.

Features –

  • These arrestors can prevent damage and banging noise to the appliances and pipes which happens due to shock of water pressure.
