I build an awesome skating rink for the kids. Now I have to flood it. I have the rink built 450 feet from the lake. The rink is 7 feet higher than the water. I have a 1.5-inch polyurethane rigid hose running from lake to rink (100% sure no air leak). I have that hose connected to a brand new, Flotec FP5172 1-1/2 HP Self-Priming High Capacity Pump running on 115V, and then from the pump a 15-foot hose to irrigate the rink. With the show about to start, I plug in the pump and it’s not siphoning water. The guys that sold the pump to me did it was ample strength.
Should I have the pump at the lake pushing the water uphill versus my current setup of pump beside rink and pulling it through 450 feet of hose? There’s barely any suction at the lake end when I pull out the hose from the lake.
