A robust, two‑part kit for rainwater harvesting that provides a secure connection between a water butt and 32mm MDPE piping. Built for tradespeople and DIYers alike, it combines a threaded tank connector with a straight MDPE joiner for a dependable, leak‑proof fit outdoors. Kit contents
- 1 x Tank Connector with Washer 1" BSPM (BUTT1BSPM)
- 1 x MDPE Straight Joiner 32mm − 1" BSPF (MDPESTR32-1BSPF) Why this fits your water‑butt needs
The BSPM threaded tank connector is moulded from durable plastic designed to resist wear in water storage applications. With a built‑in washer and a securing nut, it delivers a solid seal to the tank surface and helps prevent drips or leaks under pressure. The MDPE straight joiner provides a direct, straight path from 32mm MDPE piping to a 1" BSPF outlet, making it straightforward to extend or link sections of pipe without complex fittings. Key technical details you can rely on
- MDPE PN10 pipe fittings are engineered to withstand up to 10 bar (approx. 145 psi), giving confidence in typical domestic water pressure scenarios and garden irrigation loads.
- MDPE fittings are known for durability, flexibility, and chemical resistance, supporting long‑term outdoor use in varying weather conditions.
- The kit uses threaded compression connections to secure a tight, leak‑free seal without requiring specialist tools, making installation practical on site. Practical applications and benefits
- Ideal for upgrading or replacing a worn water butt connection, enabling reliable rainwater transfer to 32mm MDPE irrigation or storage piping.
- Suitable for indoor or outdoor installations, weatherproofing to cope with rain, frost, and sun exposure.
- Two essential fittings in one kit reduce guesswork and extra hardware purchases, helping tradespeople keep on site timing tight. How it compares and why it matters
Compared with single‑component fittings, this kit offers a complete, compatible pairing: a 1" BSP threaded tank connector plus a 32mm MDPE straight joiner that aligns directly with MDPE piping and BSP outlets. The combination supports a straightforward transition from tank to pipe, with a secure seal ensured by the washer and nut and a robust MDPE connection capable of handling typical garden irrigation demands. Tips for best results
- Clean and cut pipe ends squarely before fitting.
- Tighten nuts firmly to compress the washer without over‑tightening to avoid damage.
- Check for leaks after initial filling and resealing if necessary.
