Description
A watering point built around your connection
Bring a 25mm MDPE supply to the wall and put the water control within reach. This backplate kit pairs a compact black/orange plastic valve with the outlet that suits your hose, irrigation tube or onward pipe.
Choose the fitting you need from the selector above. Each option is one working arrangement, with a local on/off valve; the photos of different outlets show the choices, not a bundle containing them all.
Match the outlet to your pipe or hose
Every kit has the same 25mm supply inlet. Use this guide to choose what connects after the valve.
| Outlet option | Connection after the valve |
|---|---|
| PVC Valve Only | Bare ¾-inch BSP male thread for your own compatible female-threaded fitting. |
| ½-inch Barb | Plastic hosetail for nominal ½-inch internal-bore hose, also described as 13/16mm irrigation tube. |
| ¾-inch Barb | Plastic hosetail for nominal ¾-inch internal-bore hose. Match the hose specification. |
| 4mm Micro Barb | Micro-tube adapter for the nominal 4mm micro-irrigation connection. |
| ½-inch Brass Barb | Brass 13mm hosetail for nominal ½-inch internal-bore hose. |
| ¾-inch Brass Barb | Brass 19mm hosetail for nominal ¾-inch internal-bore hose. |
| 20mm MDPE Joiner | Compression outlet for 20mm outside-diameter MDPE pipe; the backplate inlet remains 25mm. |
| Female Quick Connector | Female snap-on socket for a matching male garden quick connector. |
| Male Quick Connector | Valve with an integral male snap-on outlet for a matching female garden hose connector. |
| GEKA | Brass claw coupling for a matching GEKA-type coupling; hose-side half is separate. |
Different fittings. Different connection methods.
A compression nut, snap-on connector and hose barb are not interchangeable.
MDPE pipe
Measure the pipe outside diameter. Prepare the end and follow the fitting instructions for liners, insertion depth and nut tightening. The joiner option reduces from the 25mm supply inlet to a 20mm outlet.
Hose or micro tube
Select the correct nominal hose bore and fit it fully over the matching barb. Use the appropriate retaining method for that hose or tube. Keep its weight and sideways pull off the valve by supporting the run separately.
Detachable couplings
Match male to female quick connectors, or use the correct mating GEKA-type half. Close the valve and release trapped pressure before disconnecting. A quick-connector gender does not describe the BSP thread behind it.
Make room for the control
Isolate and depressurise the supply before installation. Fix the three-hole backplate to a sound surface and support the supply pipe separately. Leave enough room to turn the valve and connect or remove the selected fitting.
The backplate has a ¾-inch BSP female socket and the valve has a matching male inlet. Follow the component instructions for sealing and tightening each joint. PTFE tape is not supplied. Restore the supply gradually and inspect the connections before use.
Before you order
Why is the ½-inch irrigation barb sometimes called 16mm?
Irrigation tubing is often named by its outside diameter, while a hose barb is matched to the bore it fits inside. The nominal ½-inch barb is commonly described as a 13/16mm irrigation connection. Check the tubing’s inside and outside sizes rather than comparing one number alone.
Are all the adapters included?
No. You receive one backplate and valve arrangement with the outlet you select. PVC Valve Only leaves a bare ¾-inch BSP male thread. Hose, pipe, clips, wall fixings and sealing materials are separate; quick and GEKA options also need a compatible mating connection.

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.
