Description
Control two hose lines
A grey plastic dial tap and separate two-way splitter give your water butt two click-on hose connections.
Use the white tap dial for the main feed and the splitter’s two white controls to manage the connected lines individually.
Choose your tank-side BSP size and adapter reach. Hoses and female hose-end connectors are separate.
One feed. Two controlled outlets.
The large white dial on the tap controls the supply to the separate splitter. Its two white branch controls let you manage the connected hose lines individually, without disconnecting them each time.
Each outlet is a male click-on nipple. Your hoses need compatible female quick connectors fitted to their ends; bare hoses do not attach directly to the nipples. Those connectors and the hoses are separate from the kit.
Both lines share the water available from the butt. Opening a second branch can affect flow through the first. The splitter adds connections, not pressure, so check that any watering equipment is suitable for your water supply.
Choose the thread and reach
The ½-inch BSP kits pair a ½-inch male/female tank adapter with a ½-inch BSP male-inlet tap. The ¾-inch BSP kits pair a ¾-inch male/female tank adapter with a ¾-inch BSP male-inlet tap. These pairings apply to both Standard and Extended selections.
Choose Standard to keep the connection closer to the tank, or Extended for extra clearance. The Extended connector measures 50mm overall, with about 40mm usable projection. These are connector dimensions, not the overall length of the assembled kit.
The ¾-inch Extended kit is pictured here. Leave room beneath the tap for the splitter, two hose-end connectors and gentle hose bends, as well as access to all three controls.
Fit it with the hoses in mind
Check the tank mounting, clearance and support before installation.
Check the mounting
Match any existing tank thread by size and gender. For a new opening, confirm wall suitability, a sound seating surface for the washers and access for the back nut. Nominal BSP size is not the required hole or drill diameter.
Leave room below
Allow space for the splitter and both hose connections. Support the hoses so their weight or movement does not pull on the plastic tap or tank adapter. Check clearance with your intended hose route when choosing the adapter reach.
Test each connection
Test the tank seal, threaded joints and both hose connections with water after fitting. Check the main tap and each branch control. You receive one selected adapter style, one tap, one splitter, a back nut and two washers; PTFE tape and tools are separate.
Questions about the tap and splitter kit
Can I control the two hoses separately?
Yes. The two-way splitter has a separate white control for each branch. The large white screw dial on the tap controls the common feed to the splitter, so it must allow water through for either branch to operate. Both hoses share the available supply, and using both together may change the flow through each line.
What fittings do my hoses need?
Each splitter outlet has a male click-on nipple. Fit a compatible female garden-hose quick connector to each hose end you want to attach. Choose the hose-end connector for your hose size as well as the click-on connection. The kit includes the splitter and its outlets, but the hoses and female hose-end connectors are separate.
Does the ¾-inch option use a ¾-inch tap?
Yes. Both the Standard and Extended ¾-inch kits pair a ¾-inch BSP male/female tank adapter with a ¾-inch BSP male-inlet tap. Both ½-inch kits use the corresponding ½-inch adapter and tap inlet. The option describes the tank-side BSP size. Check the full connection details rather than measuring the outside of a thread as if it were a hose.
When should I choose the Extended adapter?
Choose it when your tank shape or mounting position needs more clearance for the tap and splitter. The Extended connector is 50mm overall with about 40mm usable projection; this is not the length of the complete assembly. Leave room for the white controls, both hose-end connectors and hose bends, and support the hoses to avoid straining the mounting.

What is BSP?
What is BSP thread size?
BSP (British Standard Pipe) is a nominal pipe-thread size, not a direct measurement of a fitting’s bore or outside diameter. For example, a ½-inch BSP male thread measures about 21mm across its outer thread crests.
These figures are approximate outside diameters of male BSP threads, to help identify the nominal size. They are not inch-to-millimetre unit conversions:
- 3/8" BSP → 16.66 mm
- 1/2" BSP → 20.95 mm
- 3/4" BSP → 26.44 mm
- 1" BSP → 33.25 mm
- 1.25" BSP → 41.91 mm
- 1.5" BSP → 47.80 mm
- 2" BSP → 59.61 mm
- 3" BSP → 87.88 mm
- 4" BSP → 113.03 mm
All our BSP threads are parallel (BSPP, to ISO 228), not tapered.
Measure across the outside of a male thread, then check its pitch and whether it is parallel or tapered. Diameter alone does not confirm compatibility. Check the product’s stated thread specification before connecting.
