Gardena Suction Hose 25 mm 4 m G1"

The Gardena Suction Hose 4 m (G1") with Non-Return Valve 09090-20 is a specialised suction hose assembly designed to transport clean water from low-level sources to a pump inlet. This 4-metre hose has a 25 mm diameter to facilitate drawing water from wells, ponds, or rainwater tanks. It uses a G1" (33.3 mm) threaded connector to ensure a secure fit with compatible surface pumps or pressure-water automation systems. A primary function of this unit is to maintain a vacuum-sealed connection between the water source and the pump during operation. The integrated non-return valve reduces priming time by preventing water from flowing back into the source once the pump is switched off.

For longevity in outdoor environments, the hose is made from materials resistant to both ultraviolet radiation and frost. The threaded connector is made from a durable zinc alloy to provide a robust mechanical connection point at the pump inlet. A stainless steel suction filter is fitted at the intake end to prevent debris from entering the hose and potentially damaging the pump components. This combination of materials keeps the assembly functional throughout varying seasonal temperatures and exposure to sunlight. Installation is straightforward because the fittings are pre-assembled, allowing immediate connection to standard G1" threaded ports.
