Hello everyone,
Anyone with experience with water pumps, advice would be appreciated.
I have a Grundfos Scala 2 water pump connected to a channel water supply pipe about 40m away using 1-1/2 inch rural poly. The pump is not that high above the water supply and ¾ of the line is flooded.
When I start the pump it runs constantly for 2-3 mins then stops saying there is no water. I opened the pump as it was running and there is water getting in. I tried pouring some water into the pump to prime it but it did the same thing. I have a valve closed on the outlet so there is nothing going out yet.
