Choosing the correct pipe diameter is essential for maintaining flow rates and preventing pump cavitation. For a pond with a surface area of 8m² or more, using 4" (110mm) bottom drain pipework is industry standard to ensure gravity-fed systems operate at peak efficiency. At Southcoast Koi and Aquatics, we provide the robust Pond Plumbing components required to build a system that lasts for years.
