Collection: Hoses

Which hose suits your pump?

The hose largely determines how much of the flow rate you actually keep. A pump capable of 15 m³ per hour will not deliver that through a thin garden hose: resistance in the line eats up the capacity. So choose the diameter to match the pump, not to match what you happen to have lying around.

What to look for

• Diameter. Keep the hose at least as wide as the pump's discharge connection. Narrower means immediate loss; over a long run, go one size wider instead.
• Length. Every metre costs resistance. Lay out no more hose than you need and avoid sharp bends and kinks — a kink acts like a half-closed tap.
• Flat roll-up or spiral-reinforced. A flat roll-up hose is light and takes up little space when rolled: handy for mobile use and emergencies. A hose with a built-in spiral stays round and can also draw suction; on a pump's suction side that is essential, because a flat hose collapses there.
• Connection. Check which coupling is fitted or required: GEKA for garden and work hoses, Storz for fire-service and construction hoses. See the couplings and adapters.
• Discharge point. Let the water run off somewhere it can genuinely drain away. Water that seeps back into the sump leaves the pump circulating the same water indefinitely.
