deep well jet pump, no pressure after rebuild
Hi, I rebuilt the impeller assembly as the old lexan impeller cracked and slid into the impeller housing.
After rebuild, reassembly, installation, and priming, can only build about 7lbs pressure, and that is after running 30 min.
The pump is a myers hj75d 3/4 hp dual pipe deep well jet pump, on a 80 ft well.
I've cut the supply to the house to rule out a leak, and see that it is pumping a small amount as the garden hose outlet which is about four feet above the tank gives me about 3gallons of water before pressure drops too low to lift any more.
