¾” BSP Water Butt Fitting with Full Flow PP Valve and 32mm MDPE Fitting

Compact ¾” BSP water butt fitting kit for rainwater harvesting, designed to deliver secure, leak‑proof connections from tank to pipework. Built for tradespeople, builders and hands‑on DIYers, it combines a robust tank connector, a full‑flow PP valve and a 32mm MDPE joiner in a single, ready‑to‑fit kit.

• 1 x Tank Connector with Washer 3/4" BSPM (BUTT34BSPM) – BSPM threaded tank connector with washer provides a tight, secure seal to water butt tanks. Made from durable plastic for indoor or outdoor use, with precise threading and a nut to keep the fitting firmly in place, helping prevent leaks at the tank surface.
• 1 x Full Flow Single Union Ball Valve PP 3/4" BSPF (VALVE34BSPF-LARGE) – polypropylene valve with BSP female threaded inlets and outlets. The full‑flow, single union design minimises pressure drop and enhances flow, while the large lever handle offers straightforward control for on/off operation in garden or workshop applications.
• 1 x MDPE Straight Joiner 32mm - 3/4" BSPM (MDPESTR32-34BSPM) – MDPE to BSPM joiner with threaded compression connections for a tight, leak‑free seal. Suitable for connecting 32mm MDPE pipe to a 3/4" BSP male threaded fitting, supporting a reliable joint in water supply and irrigation runs.

Key benefits include a corrosion‑resistant PP valve, robust plastic construction for weather exposure, and a design that keeps maintenance straightforward. The kit is ideal for rainwater harvesting systems, irrigation setups, or any project requiring a secure link between a water butt and 32mm MDPE piping.

Practical tips and scenarios

• Ensure matching thread sizes (3/4" BSPM/BSPF) and pipe diameter (32mm MDPE) when planning connections.
• Use the tank connector with washer to create a solid seal against the water butt surface, minimising drips at the tank outlet.
• The full‑flow valve is suited to garden taps, irrigation lines, or temporary water transfer where clear on/off control is needed.
• For longer runs, pair the MDPE joiner with straight lengths to maintain efficient flow and reduce potential friction losses.
