Whole-house plumbing refers to the network of pipes, fixtures, and connections that bring fresh water into your home and carry waste safely away. This includes supply lines, drain lines, shutoff valves, and the connections to sinks, showers, toilets, and appliances. When one area of this system begins to fail, it often indicates that the rest of the piping is nearing the end of its lifespan. Whole house repiping ensures that every pipe and connection is replaced, giving your home a completely refreshed plumbing system that works like new.
