Pipes vibrating or banging can be annoying and possibly dangerous. The annoying kind can be something as simple as a shut off valve at a fixture that is not fully open allowing a rubber washer to vibrate or a vacuum breaker on your outside spigot. Make sure the valves under your sink are open all the way and that you’re outside faucets are turned off when not in use. The dangerous kind of vibrating or banging can be caused by excessive water pressure and you may need a pressure reducing valve or an expansion tank on your water heater. Your Ben Franklin plumber has the experience and tools required to determine what’s causing the problem and fix it, before it drives you crazy or worse yet causes water damage to your home.
