Slide the layflat over the tail and tighten the clip. That is the whole assembly.\u003c\/p\u003e\n\u003cp\u003eThe discharge can be set to run either vertically or horizontally. In a narrow sump or a deep footing, vertical keeps the hose rising straight out of the chamber with nothing pressing against the walls. In a shallow puddle, a crawl space or under a floor where there is no headroom, horizontal lets the hose run away flat instead of standing up and folding over on itself. Being able to switch it means one pump suits both, rather than you working around whichever orientation it happened to come in.\u003c\/p\u003e\n\u003ch3\u003eExpected performance\u003c\/h3\u003e\n\u003cp\u003eEstimated flow through the supplied 20m of 50mm layflat with the hose discharging freely.

Going from 10m to 20m of 50mm layflat costs around 3 percent of the flow, which is smaller than the margin of error on the estimate. Rather than ask you to pick between two options that perform the same, we supply the longer one, since running short stops a job and running long does not.

The SPK530 kit clears indoor floods, with reinforced hose for steps and doorways and a pump that takes water down to 1 mm. This kit is for excavations and site water: bigger bore, more flow through the hose, and a pump built for daily site abuse. If you need both, most fleets carry both.\u003c\/p\u003e\n\u003ch4\u003eCan I add more hose?\u003c\/h4\u003e\n\u003cp\u003eYes, and at 50 mm it costs very little. Another 20 m would take roughly another 3 percent off. You need a 50 mm joiner and a second clip. Get the water somewhere safe as directly as you can, and avoid tight bends, which cost far more than length does.\u003c\/p\u003e\n\u003ch4\u003eWill it pump silty or muddy water?\u003c\/h4\u003e\n\u003cp\u003eIt passes solids to 6 mm and handles the grit and sand that comes with most site water. Where silt has settled and needs stirring back into suspension, a pump with an agitator is the right tool, because a standard dewatering pump will simply pump clear water off the top and leave the silt behind.\u003c\/p\u003e\n\u003ch4\u003eWhy Tsurumi rather than a cheaper 2 inch pump?\u003c\/h4\u003e\n\u003cp\u003eLongevity and serviceability. The anti-wicking cable entry protects against one of the commonest causes of site pump failure, the motor protector cuts in before damage rather than after, and a Tsurumi is worth repairing rather than replacing.
