    Default Pump noise after seal change

    I just changed the seal in a Hayward 1 hp pump and now the pump I running a little noisy. No leaks and pressure is fine. Any ideas out there as to what may cause this before I tear it apart?

    Welcome to The Forum!

    My first thought is that the impeller might not be fully tight. The other thing that jumps to mind is that a pebble, or something, might have gotten into the housing when you did the change out.

    I checked out the pebble situation in the housing and found a lot of DE(I was putting DE in when all this was happening) I cleaned all up and tried again to find the noise still there. Now I'm beginning to think DE has gotten into a motor bearing. Is it worth replacing a motor bearing or will the DE eventually go away?
    Thanks
