    THe O ring on the back of the pump blows out every other storm. I think it s the pressure relief on the backside of the pump. I carry spare o rings but think this is a little excessive. Anyone else have this issue and a fix? Thanks

    I had that happen once to my exv but just a new o ring it never happened again. Have you checked the psi of the pump lately. It may be dialed in to high resulting in blowing out the o ring?

    Thanks for the your insight, I'll look into that. Does a fisher dealer need to check it or is there a spring or something that regulates it?
