150mm PVC Corrugated Overflow


The 150 mm PVC corrugated water tank overflow is a specialized product designed specifically for steel water tanks. Its main purpose is to allow excess water from the tank to be safely and efficiently directed into the stormwater drainage system. This product is easy to install, with pre-marked indents and a flanged outlet with pre-moulded holes for a quick and straightforward installation process.

The 150 mm PVC corrugated water tank overflow has been certified under the AS / NZ 4020 standards for potable (drinking) water, ensuring that it is safe for use with drinking water. It is made from UV-stabilized UPVC, which provides added longevity and durability. Its large 150mm size allows for maximum flow with no restrictions, making it an effective choice for managing excess water.

The main benefit of the 150mm overflow compared to the more standard 100 mm is its size, which is more than twice the flow cross-section of a 100 mm PVC corrugated water tank overflow. This allows for greater flow through the overflow, making it an ideal choice for larger water tanks or for applications where a higher flow rate is required. Designed for easy connection to standard plumbing fittings, as well as water tank-specific components such as flap valves and mosquito-proof screens. This makes it a versatile and practical choice for a wide range of applications. Whether you are looking to upgrade your existing water storage system or are in the process of installing a new one, the 150 mm PVC corrugated water tank overflow is an excellent choice for ensuring that excess water is safely and effectively managed.
