A practical, all-in-one kit for rainwater harvesting that fits water butt tanks securely and keeps flow under control. Designed for tradespeople, installers and DIYers, it pairs a 1" BSP tank fitting with a full-flow valve and a MDPE connector for straightforward, leak‑resistant setup. What’s in the kit - 1 x Tank Connector with Washer 1" BSPM - 1 x Full Flow Single Union Ball Valve PP 1" BSPF-LARGE - 1 x MDPE Straight Joiner 32mm - 1" BSPM Component overview The BSPM Threaded Tank Connector with Washer is a plastic fitting intended for mounting on water butt tanks. It uses a washer and nut to help create a seal against the tank surface, reducing the risk of drips once tightened. The connector is moulded from durable plastic suited to outdoor use, with precision threads for a snug, align-and-tighten installation. The Full Flow Single Union Ball Valve PP provides a reliable on/off control with BSP female threaded inlets and outlets. Made from polypropylene, it resists corrosion and impact, offering long-term performance in typical rainwater and garden‑watering applications. The large lever handle gives easy operation when your hands are dirty or wearing gloves, and the full-flow design helps minimise pressure drop through the valve. The MDPE Straight Joiner 32mm - 1" BSPM is a straight connector that links 32mm MDPE pipe to a 1" BSP male thread. MDPE fittings are known for durability and chemical resistance, making them suitable for water supply and irrigation lines. The joiner uses a threaded compression connection on the 32mm MDPE side to form a tight seal without special tools, while the BSPM side accepts the valve or tank fittings. Ideal uses and practical notes - Perfect for retrofitting or upgrading rainwater harvesting setups on domestic or small commercial tanks. - Suitable for connecting MDPE irrigation or garden mains to a water butt with a secure, controllable discharge point. - Ensure the BSP threads are clean and lightly oiled or sealed with appropriate thread sealant or PTFE tape as required; tighten fittings to the manufacturer’s recommendations to achieve a reliable seal. The kit provides a straightforward, robust solution that aligns with practical, hands-on installation needs, helping you manage rainwater storage reliably from tank to hose.
