i need some help. i just dissembled my loop all was running fine. then today i put it back together adn the pump ran but no water was moving. the first thing i noticed was it was trickling threw like normal. then i unplugged everything and filled it some more and then bam it jsut stopped moving water. so does this mean the pump is dead.
al so how do i fix scratches in a water block the bottom of my block is very veyr scrathed and dirty.
