This set includes:

• 1 x 1" BSP Male to 3/4" BSP Female Brass Water Butt Outlet (WB-BR-34BSPF-1BSPM)

The 1" BSP Male to 3/4" BSP Female brass outlet is a sturdy and versatile connector, ideal for rainwater harvesting systems and fluid storage containers. Manufactured from high-grade brass, it offers excellent durability and is resistant to harsh weather conditions. This fitting effectively reduces a 1" BSP male thread to a 3/4" BSP female thread, making it easy to adapt different pipe sizes in your setup.

If your barrel or tank already has a 1" BSP female thread, this fitting can be screwed in directly. For untapped containers, simply drill a 33mm hole and secure the fitting using the supplied back nut and washers to create a watertight and secure seal.

To install, remove the back nut and one washer, insert the fitting through the pre-drilled hole, making sure the remaining washer sits on the inside. Then tighten the back nut. This installation method ensures leak protection and a solid, lasting connection — a smart choice for customising or upgrading your water butt system.

The 3/4" BSP In-Line Valve is a reliable and durable component for managing water flow in your irrigation or storage systems. Featuring BSP male threads at both ends, it is easy to install and compatible with standard pipe fittings. Made from robust plastic, the valve offers long-lasting performance and resistance to wear and tear.

Its soft-turn mechanism enables smooth and precise on/off control. The comfortable grip and reliable seal make this valve ideal for home and garden use, as well as commercial applications requiring frequent adjustments. Its leak-resistant design preserves system integrity and minimises maintenance needs.

The PTFE (Polytetrafluoroethylene) tape provides a secure seal for threaded pipe connections. Known as plumber’s tape, it is simple to apply by hand and conforms well to threads, even in tight or awkward spaces. Resistant to heat, pressure, and chemicals, it is a go-to sealing solution for both DIY and professional use.

The 34mm HSS Hole Saw Cutter is designed for accurate and efficient drilling in a variety of materials such as plastic, wood, and metal. Its sharp teeth and durable high-speed steel construction ensure consistent performance and clean cuts. Ideal for creating entry points for fittings, such as the 1" BSP male connector in rainwater barrels.

This tool minimises vibration and enables quick attachment to power drills. A reliable choice for plumbing projects, installations, or repairs — perfect for anyone in need of precision drilling and professional results.
