The reinforced hose goes on the suction side with the strainer fitted to the far end, and the layflat goes on the discharge.

The WB20 passes 6 mm solids, and the strainer is what stops anything larger reaching a cast iron impeller.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePrime before starting.\u003c\/strong\u003e The WB20 is a self-priming centrifugal pump, but self-priming means it will clear air from the suction line once the casing is wet, not that it starts dry. Fill the pump casing with water through the priming plug until full, then start the engine. Running dry destroys the mechanical seal.\u003c\/p\u003e\n\u003cp\u003eKeep the suction lift as short as you can and the suction hose as straight as you can. Priming takes longer the higher the pump sits above the water, and every bend on the intake side costs you more than one on the discharge.\u003c\/p\u003e\n\u003ch3\u003eExpected performance\u003c\/h3\u003e\n\u003cp\u003eEstimated flow through the full 36m of 50mm hose supplied.

It needs a reinforced suction hose that will not collapse under vacuum and a delivery hose on the other side. This kit supplies both, correctly sized in 50mm to match the ports.\u003c\/p\u003e\n\u003ch4\u003eWhy are the two hoses different?\u003c\/h4\u003e\n\u003cp\u003eThe suction hose works under vacuum, so it must be reinforced or the pump will pull it flat and lose prime. The delivery hose works under pressure, which holds it open, so layflat is fine there and it is lighter and packs down far smaller.\u003c\/p\u003e\n\u003ch4\u003eCan I use layflat on the suction side?\u003c\/h4\u003e\n\u003cp\u003eNo. It will collapse as soon as the pump draws and the pump will not prime. Reinforced on the suction, layflat on the delivery.\u003c\/p\u003e\n\u003ch4\u003eDoes self-priming mean I do not have to prime it?\u003c\/h4\u003e\n\u003cp\u003eNo. Self-priming means the pump can clear air out of the suction line once its casing is wet. You still have to fill the casing with water through the priming plug before the first start, and running it dry destroys the mechanical seal.\u003c\/p\u003e\n\u003ch4\u003eCan I run it in a cellar or a garage?\u003c\/h4\u003e\n\u003cp\u003eNo. Petrol engines produce carbon monoxide, which is lethal in an enclosed space. Site the pump outdoors and run the suction hose in, or use an electric \u003ca href=\"https:\/\/floodandwaterpumps.co.uk\/collections\/submersible-pumps\" title=\"Submersible water pump\"\u003esubmersible\u003c\/a\u003e pump instead.\u003c\/p\u003e\n\u003ch4\u003eIs a strainer included?\u003c\/h4\u003e\n\u003cp\u003eYes, with the pump, along with hose couplings, washers and clips.

At this flow rate the full run costs around 14 percent against a short one, because friction rises steeply with flow. It is worth it for the reach on a flood or site job, but if your discharge point is close, use less hose and you will move more water.\u003c\/p\u003e\n\u003ch4\u003eDoes it need two-stroke fuel?\u003c\/h4\u003e\n\u003cp\u003eNo. The GX120 is a 4-stroke, so it runs on straight unleaded with oil in a separate sump.
