In plumbing, the 'hot' and 'cold' sides refer to the two types of water lines that serve fixtures like sinks, showers, and appliances. The hot side delivers water heated by your water heater, while the cold side supplies water directly from your main water line, unaffected by the heater. Both are essential for daily use, providing water at different temperatures for bathing, cleaning, and cooking. It's crucial to correctly connect these lines during installation to ensure the proper function of your plumbing fixtures.
