Robert B Addison , VT June 20, 2014 Water was leaking from the pump shaft seal I installed the pump seal and impeller kit. I have a lot of experience repairing machinery, but this was not complicated. The instructional video was very good, and anyone who can use basic tools should be able to do this. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
