When the water level drops to the last few millimetres, the pump naturally begins to draw in air. Without a non-return valve, any water still sitting in the discharge hose can then flow back through the pump and return to the area you have just cleared, which can look like the pump has stopped working, when in fact it is behaving exactly as expected in those conditions.\u003c\/p\u003e\n\u003cp\u003eThis is not a pump fault; it is simply how any open discharge line behaves at very low water levels, particularly with longer hose runs or where water is lifted over a height.

The water already pumped stays in the hose instead of draining back, so you keep the ground you have gained and the pump re-primes faster when the water level rises again. The 25 mm hose tail threads onto the valve, ready for a standard 25 mm (1″) discharge hose secured with a hose clip.\u003c\/p\u003e\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cp\u003e•    Prevents backflow, pumped water can’t drain back through the pump when the level drops or the pump stops.\u003cbr\u003e•    Ideal for shallow-water and low-level pumping, where air draw at the end of a pump-down is normal.\u003cbr\u003e•    Reduces airlock problems on longer hose runs and lifts over height.\u003cbr\u003e•    Direct fit for the SPP2 Puddle Pump, no tools or modifications beyond a hose clip.\u003cbr\u003e•    Two-piece kit: 1″ BSP non-return valve plus matching 25 mm hose tail.\u003c\/p\u003e\n\u003ch3\u003eFitting note\u003c\/h3\u003e\n\u003cp\u003eScrew the non-return valve onto the pump outlet, fit the hose tail to the valve, then push on your 25 mm discharge hose and secure with a hose clip. Keep hose runs as short and direct as practical – very long runs or high lifts increase the volume of water the valve has to hold.
