A home’s water supply system delivers cold and hot water to faucets, showers, and appliances. Understanding how it works is an important part of earning the Plumbing merit badge. This system starts with a main water line that brings cold water into the house. From there, pipes distribute the cold water to sinks, toilets, and other fixtures. Part of the cold water goes to the water heater, where it is heated and sent through separate pipes to provide hot water.
The two sets of pipes—one for cold and one for hot water—run throughout the house, ensuring you have the right temperature water where you need it. Valves are placed along the system to control water flow, and faucets mix hot and cold water for comfortable use. The Plumbing merit badge helps Scouts understand how these systems work and why they are designed this way.
To protect the system from freezing in winter, insulate exposed pipes in cold areas like basements or attics. Use pipe insulation foam or heat tape for added protection. Draining outdoor faucets and shutting off their water supply can also prevent freezing and bursting. These steps keep your plumbing system safe and working all year long.
The drainage system in a house removes wastewater from sinks, toilets, showers, and appliances like washing machines. It’s designed to keep water flowing out efficiently and safely. Learning how this system works is an important part of earning the Plumbing merit badge. The system includes drains, pipes, and vents, all working together to keep your home sanitary and odor-free.
Drains carry wastewater from fixtures to larger pipes called drainpipes. These pipes slope downward to help gravity move the water toward the main sewer line or a septic system. Vents are just as important as drains. They allow air to flow into the pipes, preventing a vacuum that could stop the water from draining. Vents also release sewer gases safely outside, usually through pipes that extend above the roof.
When Scouts learn about the drainage system for the Plumbing merit badge, they see how everything connects. Properly installed drains and vents prevent clogs, backups, and unpleasant odors, making the system work smoothly and safely. Understanding this system helps Scouts appreciate how plumbing keeps homes clean and healthy.
