All water supply systems use a combination of pipes (of different dimensions and materials), valves and outlets to deliver water to building users. Some water supply systems also use storage tanks and pumps.
Your underground water line is the main water supply to your home, entering at ground level or below. For this reason, you must choose the correct pipe for the purpose. Imagine the inconvenience if your water line failed to operate…
The method in BS EN 806-3 is used for calculating the hot and cold water pipe size in multiple residential buildings, yet if it is used for single residential dwellings then the pipework is at risk of being oversized.
9 sie 2023 · Best For: Hot and cold potable water supply. Advantages: Resistant to corrosion; can handle hot water; long lifespan. Limitations: More expensive than PVC; requires careful installation to avoid leakage.
Figure 2. Flow rate affects how hot and cold water inter-act in the piping during hot-water delivery. A flow rate of 3 to 4 gpm creates a “plug flow” (top), which pushes cold water out of the pipe without much mixing, minimizing wasted water and time-to-tap. At low flow rates (bottom), a thin stream of hot water rides up on top of the cold
