Fixing a water hammer is generally not overly expensive, with basic material costs ranging from $15 to $50 per arrestor if you install them yourself under sinks or at washing machine connections. If you hire a professional licensed plumber, total costs typically range from $150 to $400, depending on labor rates and how many arrestors need to be placed across your home. The price only escalates significantly if hidden pipes within walls must be accessed or if a main pressure-reducing valve (PRV) must be replaced. Verification: Turn on and off high-velocity fixtures to confirm the banging noises have stopped.
