What is water hammer?
Water hammer is a plumbing phenomenon that causes a loud banging or knocking sound in pipes when a faucet or valve is turned off or on. You might also experience this with toilet flushes. This happens because of the sudden stoppage of water flow, which causes a surge of pressure to build up in the pipes. The sound of water hammer can be alarming and disruptive, and it can also cause damage to pipes, valves, and appliances connected to the plumbing system.
Water hammer can occur in both residential and commercial plumbing systems, and it is more common in older buildings with outdated plumbing. It is caused by a variety of factors, such as high water pressure, water flow velocity, and the length and diameter of pipes. If you experience water hammer in your home or building, it is advisable to consult a professional plumber to diagnose the problem and recommend the best course of action to prevent further damage.
What are the causes of water hammer?
Water hammer is a common problem that occurs in plumbing systems and can result in loud banging or thumping noises. The main causes of water hammer include sudden valve closure, high water pressure, and loose pipes. Sudden valve closures occur when a valve is closed too quickly, and the momentum of the flowing water causes pressure waves to form. High water pressure can also cause water hammer by increasing the force of the pressure wave. Loose pipes can create water hammer by allowing the pipes to move and vibrate during water flow, and the sudden stop of flow can create a hammering sound.
Additionally, air bubbles in pipes can be caused by poor installation and can also cause the noise associated with water hammer. Finally, worn-out or misaligned pipe fittings can also lead to a sudden change in water pressure, so these should be inspected and replaced when necessary. Water hammer can seriously damage your plumbing system if it’s not dealt with. As a result, you’ll want to address the cause of the problem as soon as possible.
How can you prevent water hammer?
Water hammer can create a loud noise in your walls and can cause pipes to rattle, vibrate, and even burst if left unaddressed. Fortunately, there are a few ways to prevent water hammer from occurring. One of the easiest solutions is to install a water hammer arrester near the valve that is causing the problem. A water hammer arrester is a small device that absorbs the pressure created by the water flow, preventing it from causing damage to your pipes. You can install these devices on washing machines, dishwashers, and other appliances that are known to cause water hammer.
Another way to prevent water hammer is to install air chambers in your plumbing system. An air chamber is a vertical pipe that is installed near valves or other areas where water flow is high. When water flows through the pipe, it pushes the air up into the chamber. This air acts as a cushion, absorbing the pressure caused by the water flow and preventing water hammer from occurring.
In addition to these solutions, it’s important to make sure that your plumbing system is properly maintained. Regular inspections and maintenance can help identify and address any issues before they become more serious. For example, if you notice any rust or corrosion on your pipes, it’s important to fix this right away to prevent them from weakening and becoming more susceptible to damage from water hammer. By taking preventative measures, you can avoid costly repairs and potential danger caused by water hammer in your plumbing system.
Overall, understanding what a water hammer is and how to stop it is essential for maintaining a properly functioning plumbing system. The water hammer phenomenon can cause damage to pipes, appliances, and fixtures while also creating unpleasant noise disturbances. By implementing simple solutions like installing water hammer arrestors or checking for water pressure abnormalities, homeowners can prevent water hammers and avoid costly repairs.
