Take control of your rainwater with the Water Butt Brass Kit 1" BSP, a robust adaptor and flow-control package for garden water butts and other storage containers. Built for durability and straightforward fitting, it lets you adapt from 1" BSP male to 3/4" BSP female, then regulate flow with a soft-touch inline valve. What’s in the kit
- Water Butt Brass 1" BSP Male to 3/4" BSP Female outlet
- PTFE tape roll
- MDPE Straight Joiner 20mm to 3/4" BSP
- In-Line Valve 3/4" BSPM (soft-touch)
- 34mm HSS Drill Bit Hole Saw Cutter Key features and how it helps you
- Brass 1" BSP Male to 3/4" BSP Female: a sturdy connector designed for rainwater harvesting setups, offering a reliable transition between pipe sizes in your water storage system.
- In-line Soft Touch Valve: a 3/4" BSPM valve with a smooth turn-on/turn-off action, making precise flow control easier during refills, transfers, or irrigation tasks.
- MDPE 20mm to 3/4" BSP Joiner: enables simple integration of 20mm MDPE piping with the 3/4" BSP outlet, reducing the need for multiple adapters.
- Drill Bit Hole Saw Cutter: included to assist hole creation in containers; 33–34mm guidance is recommended to accommodate the 1" BSP male thread, with washers and a back nut providing a seal when mounted.
- Sealing and installation: PTFE tape is supplied to help seal threaded connections; the kit’s design supports both threaded and direct-fit installations, using the washers and back nut to secure the brass adaptor against leaks. How to install (quick reference)
- For threaded containers: screw the 1" BSP male into the existing female thread and tighten with the back nut, using PTFE tape on threads.
- For non-threaded containers: drill a suitable hole (use the included drill bit), insert the 1" BSP male through the hole, place the remaining washer inside, then tighten the nut to seal.
- Connect MDPE pipe with the 20mm joiner, then route water through the inline valve for controlled output. Designed for DIYers and tradespeople alike, this kit provides a durable, adaptable solution for upgrading rainwater harvesting setups, improving reliability and control without specialised tools beyond the included drill bit.

All of our C16 and C24 graded timber is regularised
Regularised timber is timber that has been processed to have a uniform shape and size. This means that the wood has been sawn and planed to remove any irregularities and ensure that each piece of wood has consistent dimensions. Regularised timber is often used in construction, particularly in the framing of buildings, as it is easier to work with and can be more efficiently installed than irregularly shaped timber.
We have one of the largest ranges of timber lengths, dimensions and grades available to buy online.
