- 1 x Tank Connector with Washer 1" BSP male thread (M) – includes washer for a seal.
- 1 x MDPE Straight Joiner 25mm to 1" BSP female thread (F) – enables a straight connection to MDPE piping. Key features and benefits
- Robust plastic construction: both components are designed to withstand outdoor use and varying weather conditions without compromising performance.
- Thread details: tank connector features a 1" BSP male thread; the straight joiner provides a 1" BSP female connection, enabling a secure, compatible link between the water butt and MDPE pipe.
- MDPE compatibility: MDPE straight joiner is intended for 25mm MDPE pipe systems, providing a direct, straight path for fluid transfer.
- Sealing and security: the kit includes a washer and associated nut to help secure the fitting and seal the joint, reducing the risk of drips.
- Pressure tolerance: MDPE fittings of this type are designed to perform under typical domestic water pressures and are rated to PN10 (up to around 10 bar, 145 psi), subject to the overall plumbing arrangement.
- Easy, tool-light installation: MDPE fittings use threaded compression connections that create a tight seal without the need for specialised equipment, making on-site install straightforward for tradespeople and DIYers. Ideal applications
- Connecting a water butt to 25mm MDPE pipe for rainwater harvesting, garden irrigation, or soakaway systems.
- Replacing worn connectors on existing water butt setups to restore a leak‑aware, secure connection.
- Use with tanks featuring a 1" BSP outlet to ensure a compatible, dependable fit. Installation tips
- Clean the tank outlet and joiner faces before assembly; insert the washer and tighten the nut to secure the seal.
- Verify that the 1" BSP threads mate cleanly between components and that the MDPE pipe seats fully into the joiner. This kit delivers a clear, practical solution for reliable water butt connections, combining robust materials with straightforward, tool-light installation.
