What Is the Tap Connector on a UK Outdoor Tap?

On a typical UK outdoor tap, the connector you screw a hose or timer onto is a BSP 3/4" thread—British Standard Pipe, three-quarter inch. A dual-zone digital water timer such as the SGW07M is made for that BSP 3/4" UK tap thread. You usually fit it by hand: align the thread, turn until snug with the washer seated, then attach hoses to the two outlets. No app is required; power comes from two AA alkaline batteries (not included), and rechargeable batteries are not recommended.

BSP 3/4" in plain garden language

BSP is the thread standard used on most British outdoor taps. The “3/4 inch” size is the common garden-tap fitting for hose connectors and many water timers. If your indoor basin uses a different thread, that does not change the outdoor tap: garden hardware is sold around BSP 3/4" for a reason.

Quick recognition checklist:

• Outdoor brass or metal tap in the yard or on a house wall.
• Male thread on the tap spout where a hose connector normally screws on.
• Standard UK garden hose fittings that already screw on without an adaptor.
• Product copy that states BSP 3/4" UK compatibility—as with the SGW07M.

If a European or US import uses a different thread, you may need an adaptor. Prefer timers that state BSP 3/4" clearly so the first fit is hand-tight and leak-minded, not a fight with the wrong pitch.

Hand-tight installation checklist

Install a plastic-bodied dual-zone timer carefully so you seal the joint without cracking the housing.

1. Turn the tap off fully and relieve pressure in any attached hose.
2. Check the timer inlet washer is present, clean, and seated flat.
3. Offer the BSP 3/4" inlet square to the tap thread—no cross-threading.
4. Hand-tighten clockwise until firm. Stop when resistance is even; do not lean on a big spanner.
5. Open the tap slowly and check for drips at the joint; a slight extra hand turn is often enough.
6. Fit hoses or drip manifolds to the two independent outlets.
7. Insert 2 × AA alkaline batteries; close the compartment for IPX5 protection against water jets.
8. Set the LCD: run time 1–360 minutes; repeat every 1–23 hours or every 1–15 days.
9. Optional: rain delay 1–15 days, child lock, and manual start for odd jobs.

Working pressure 0.05–0.8 MPa and temperature 4.5–45°C apply once water is flowing. Stay inside those limits for lawns, flower beds, raised beds, greenhouses, sprinklers, and drip systems.

Two outlets on one BSP tap

One BSP 3/4" connection feeds the timer; two outlets leave it. That is the point of a dual-zone design: one tap, two schedules. You might put a lawn sprinkler on zone one and raised-bed drip on zone two, each with its own duration and frequency. Stagger starts if your supply prefers one zone at a time—especially on long or thin hoses—without expecting the timer to increase pressure.

The body is plastic; treat it as weather-ready garden equipment within IPX5 and the temperature band, not as something to overtighten or leave pressurised through a hard frost outside the rated range. Child lock helps stop accidental programme changes at a low outdoor tap.

Washers, leaks, and common fit mistakes

Most “it won’t seal” moments are washer or alignment issues, not a mysterious tap standard.

• Missing or twisted inlet washer → drip at the tap joint.
• Cross-threaded start → grit feeling and sudden leak—back off and restart by hand.
• Overtightening plastic → stressed body; hand-tight plus a gentle nudge is the goal.
• Wrong-thread adaptor stack → extra leak points; use a true BSP 3/4" match when you can.

After fitting, run a short manual cycle and watch both the tap joint and the outlet couplings. Dry joints after a minute of flow usually mean you are done.

Boundaries

BSP 3/4" describes the mechanical thread—not water pressure, not flow rate, and not battery life. The SGW07M does not charge; it uses alkaline AAs. It has no app. It does not boost pressure. It will not fit a non-BSP tap without the correct adaptor, and forcing mismatched threads risks damage. Specs you can rely on here are only those listed: dual zones, 1–360 minute durations, 1–23 hour or 1–15 day frequencies, 1–15 day rain delay, manual mode, child lock, LCD, IPX5, plastic body, 0.05–0.8 MPa, 4.5–45°C, and the UK BSP 3/4" inlet.

FAQ

Is BSP 3/4" the same as a normal UK garden hose fitting?

For most outdoor taps, yes—the common hose connector and many timers share that BSP 3/4" thread.

Do I need tools to fit the timer?

Hand-tightening is the normal method. Avoid heavy tools on a plastic timer body.

Can one tap run two watering lines?

Yes—via the two independent zones on a dual-zone digital water timer such as the SGW07M, each with its own schedule.
