This item is an outlet tap designed for drawing water from storage containers such as water butts, rain barrels, or storage tanks. It consists of three parts: a 1/2" BSP threaded adaptor requiring a 26mm hole. To install, follow these steps: Remove the nut and washer. Insert the adaptor through the prepared hole. Replace the washer and nut from the inside. Tighten gently to avoid stripping the threads. Once the adaptor is secured, you can attach the nickel-plated full-flow butterfly valve. To ensure the handle faces upwards when tightened, use a small amount of plumber's tape on the thread for leak-free adjustment. Finally, screw on the universal garden hose male adaptor, which is compatible with any quality hose connector brand.
