HydroSure Vari-Flow Valve - 4mm - Black - Pack of 5

The HydroSure Vari-Flow Valve is designed to fit hoses with a 4mm internal diameter.

Yes, the barbed connection allows it to function as a coupler between two lengths of 4mm internal diameter feeder hose.

The valve typically has a mechanism (often a rotating part) that you turn to open or close the water passage, thereby controlling the flow. The exact operation may vary slightly but the principle is to restrict or open the valve's aperture.

The HydroSure Vari-Flow Valve comes with a 1 Year Manufacturer's Guarantee.

These valves are generally designed for low-pressure irrigation systems. It is not recommended for high-pressure applications.

This pack contains 5 HydroSure Vari-Flow Valves.

While primarily designed for surface-level irrigation of pots, boxes, and baskets, they can be used in in-ground systems provided they are compatible with the hose size and pressure requirements.

Ensure the valve barb is fully and securely inserted into the 4mm internal diameter hose. Check the hose for damage or degradation; replace if necessary. Ensure the hose is the correct size (4mm internal diameter).

Check for any debris obstructing the valve's internal mechanism. Ensure the valve is fully turned to the closed position. If the issue persists, the valve may be damaged and require replacement.

Slightly soften the end of the hose with warm water (do not use boiling water). Ensure you are using a hose with the correct 4mm internal diameter. Apply gentle, even pressure.
