How to choose a garden watering hose?

Size: inside diameter and length

Garden hoses are referred to by their inside diameter in inches (such as 1/2", 5/8", 3/4"). For short distances and a hand spray gun, 1/2" is often sufficient; on a long line, with a sprinkler or several watering outlets, a larger diameter carries the water with less loss. Pressure loss also increases as the hose gets longer, so choose a length that reaches the farthest watering point and do not buy it unnecessarily long. Check that couplings and quick connectors are the same size as the hose diameter.

Original editorial recommendation; not a clause of a standard.

Construction: layers, braid, UV

In a durable garden hose the outer layer is UV-resistant against sunlight, the intermediate layer is opaque and prevents algae from forming inside, and the braid reinforcement in between provides pressure resistance. A single-layer hose without braid kinks and folds more easily and may swell under pressure. Burst pressure and operating temperature vary by product: two hoses from the same manufacturer can show different values such as 24 bar and 45 bar, or 0…+40 °C and -20…+65 °C. When comparing, read the product's own technical value.

Use and storage

• After use, turn off the tap and release the pressure in the hose.
• Do not leave the hose in the sun or full of water; store it on a reel or hanger.
• Drain the water inside before winter; check the product's lower temperature limit.
• Check coupling seals and clamps at the start of the season.

Frequently asked questions

Can drinking water be taken from a garden hose?

A description given for garden watering does not mean suitability for drinking water. For drinking water, the product must have a certificate for contact with drinking water; do not use a garden hose for this purpose.

Why do algae form inside the hose?

In a hose that lets light through, algae can form as the water left inside is exposed to sunlight. Hoses with an opaque intermediate layer are made to prevent this.

Is a hose with a higher burst pressure always better?

Burst pressure is an indicator of durability but not the only criterion; diameter, length, flexibility, UV resistance and temperature range must also suit the use. Values vary by product; read the product's own technical data.
