I recently bought a new Sta-Rite SNE-L 1HP Shallow Well Jet Pump. I am in Alaska and it came all the way from Florida. I have a CSV valve and that all works great. On first start up it started pumping right away. I had a small leak on the outlet that I didn't fix right away. When I did fix the outlet leak I realized that what was leaking worse was the pump shaft seal. I called the dealer and they said I could return the pump. I decided to get a new seal kit instead and put it in myself. Perhaps it was a factory defect. I just finished that job and it still leaks though slower.
