Water Hammer: Causes, Risks and How to Fix It Water hammer is the familiar loud “bang” or “hammering” sound that can happen in home plumbing systems when a faucet closes, a valve shifts, or a supply line experiences a sudden change in flow. The noise comes from pressure waves traveling through the pipes—an effect similar to what you’d feel if you abruptly stopped moving water in a moving pipe network. Although it may seem like a minor annoyance, water hammer can indicate pressure and flow conditions that may gradually damage plumbing components. Understanding why it happens is the first step toward fixing it safely and preventing repeat incidents. What causes water hammer Water hammer typically occurs when moving water is forced to stop quickly. Common triggers include closing a faucet rapidly, turning off an appliance valve, flushing toilets, or cycling solenoid valves in dishwashers and washing machines. The faster the ... Read more »
Backflow Preventers Explained: When You Need One A backflow preventer is a plumbing device designed to stop backflow —the unwanted reversal of water flow that can pull contaminants into a building’s drinking-water lines. Instead of water moving normally from the supply into your home or facility, pressure changes can force water to flow in the opposite direction, creating a potential health risk. Backflow can occur when there’s a drop in water pressure on the public side (for example, during a main break or heavy demand). If your plumbing has certain connections or risk sources, contaminants may be drawn backward through the system. What backflow preventers protect against Backflow can move a wide range of substances into potable water systems, including chemicals used in irrigation, wastewater from drains connected to irrigation lines, or other contaminants associated with cross-connections. The goal of a preventer ... Read more »
