How to Connect a Garden Hose to a Garden Tap

Check what kind of tap you have

Before you connect anything, look at the end of the tap. The right fitting depends on what you see, and picking the wrong one is the most common reason for leaks.

Most outdoor taps in the US have a threaded outlet. Your hose's female coupling screws straight onto it. Some taps, especially on indoor sinks, utility rooms or in other countries, have a smooth or ribbed nozzle with no thread. Those need an adapter, usually called a tap connector.

What you need before you start

The job takes a few minutes and needs very little. Gather these items first so you are not hunting for parts with the water running.

• Your hose, with a working female coupling on one end
• A rubber washer (gasket) that fits inside the coupling
• A tap connector, only if your tap has no thread
• A nozzle, sprinkler or spray gun for the other end
• A dry cloth to wipe the threads clean

Connect the hose to a threaded tap, step by step

Follow this order and you should get a tight seal without tools.

• Turn the tap fully off. Make sure the nozzle or spray gun on the far end is also closed or set to off.
• Look inside the female coupling. You should see a flat rubber washer. If it is missing, cracked or flattened, replace it. This small part does most of the sealing.
• Wipe any grit off the tap threads and the coupling so the threads do not bind.
• Hold the coupling square to the tap and start turning it clockwise. Start it slowly so it does not cross-thread. It should turn easily at first.
• Tighten by hand until it feels snug. Do not use pliers or a wrench on plastic fittings, since you can crack them or crush the washer.
• Open the tap slowly, about a quarter turn, and check the joint. If water drips, close the tap and tighten slightly or check the washer.
• Once there is no leak, open the tap further and open the nozzle.

Connecting to a tap with no thread

A smooth nozzle needs a tap connector. Universal versions have a rubber-lined collar that grips the tap and a tightening screw or lever. Slide the connector over the nozzle as far as it goes, tighten it by hand until it holds firmly, then attach your hose to the connector's outlet.

Pull gently on the connector before turning the water on. If it moves, tighten it more or choose a connector sized for your nozzle. Open the water slowly, because a connector that is not seated well can pop off under sudden pressure and spray you.

Indoor taps with mixer handles or aerators sometimes need the aerator unscrewed first so the connector can seat properly. Check your tap before forcing anything.

Connecting a hose reel, including a Gardena reel

The steps are similar with a hose reel, but there is usually one extra link. Most reels have a short supply hose or an inlet fitting that goes to the tap. The hose on the reel drum is already attached inside, so you connect the reel to the tap, not the hose itself.

For a Gardena or other branded reel, check the manual that came with it. Many use a tap connector that clicks onto a matching fitting, so the reel can be removed quickly. Fit the tap connector on the tap first, following the same steps as above. Then click or screw the reel's supply hose onto that connector.

Unwind enough hose before you turn the water on. A reel with the hose mostly wound can build up pressure inside the coils and may leak at the drum. Keep the reel on a flat, stable spot so it does not tip while you pull the hose out.

Choosing a hose that connects cleanly

Fit matters as much as technique. Check that the coupling on any hose is a standard size for your tap, and look for a built-in gasket or O-ring. In our best garden hose comparison, the Flexzilla 100 ft hose lists aluminum fittings and an O-ring for a leak free connection, and the Flexi Hose expandable model lists 3/4 inch brass connectors that fit typical US outdoor taps.

Metal fittings tend to hold up better than plastic ones if you tighten and loosen them often. If you are still deciding which hose to buy, the garden hose comparison lists fitting material, length, weight and inner diameter side by side so you can match a hose to your tap and yard.

Safety and care tips

Open and close the tap slowly. A sudden rush of water can make a loose coupling slip or a hose whip around. Keep the hose away from electrical outlets, extension cords and power tools when you work.

If you will be spraying near your face, such as when clearing a clogged nozzle, wear eye protection. In cold weather, disconnect the hose and drain it. Water left in the hose or tap can freeze and crack the tap or fittings.

Frequently asked questions

Why does my hose leak at the tap even when it is tight?

The washer inside the coupling is usually worn, flat or missing. Replace it with a new rubber washer of the same size. Also check that the threads are clean and the coupling is not cross-threaded.

Do I need tools to attach a hose?

Usually no. Hand-tight is enough for most hose couplings. Tools can damage plastic fittings and crush the washer, which then causes leaks.

Should I leave the hose connected all the time?

It is better not to in freezing weather. Leaving it attached lets water sit in the tap and hose, which can freeze and cause damage. In warm weather it is fine, but turn the tap off when you are done.

How do I turn on the water to my outside hose?

Find the outdoor tap, which often has a round handle or a lever. Turn it counterclockwise to open. If you have an indoor shut-off valve for the outside line, make sure that is open too, especially after winter.
