Let's break down water hammer. a) Define water hammer: Water hammer is a banging or knocking sound in plumbing pipes caused by a sudden change in water flow velocity, which creates a pressure surge. b) Causes of water hammer: The primary causes of water hammer are: • Sudden closure of valves (e.g., faucets, washing machine valves), which abruptly stops the moving water. • High water pressure in the system. • Loose pipes that are not properly secured, allowing them to vibrate against supports or walls. • Air trapped in the pipes, which can compress and expand, causing noise. c) Remedies of water hammer: Remedies for water hammer include: • Installing water hammer arrestors (shock absorbers) near quick-closing valves to absorb pressure surges. • Securing loose pipes with pipe clips or straps to prevent movement. • Bleeding air from the system by running all faucets until the water flows smoothly. • Reducing overall water pressure in the system by installing a pressure reducing valve if the pressure is excessively high. • Replacing faulty or worn-out valves that close too quickly.
