As long as your drain pumps are working fine, I wouldn't bother swapping them out at this point. What I did do, however, is re-locate them so they are directly connected to the bag. My rear drain pumps would not work consistently, and in speaking with Jason @ wakemakers, it was suggested to relocate them. This will help remove the possibility of an air gap forming in the hose from the bag to the pump, and make them more reliable. Wakemakers made up the new direct connections for me. They are @ the very bottom left of this picture. I didn't need one for my center sac because it was already done.
