I have a 1hp Hayward super pump and the rear seal is leaking. I went to my local Leslies store, where I bought the pump 5 years ago, and got a new rear seal and a gasket kit. Replacing the seal was pretty simple, but it still leaks. I sanded any rust off the shaft before I installed the new seal and used gloves to handle the parts. I did not use any type of lubricant or sealer on the new seals. Is there something I am missing?
