When you plumb in your pump put a ball valve on the outlet side to control your flow and you can introduce Star-San at the top and pump it throughout the system to clean your pump between brews. Just do not operate them dry, keep em primed and you will get years of great service from either. I flush mine after I am done brewing, and again before I start the next batch. I have never had any issue doing it that way. Remember to use PTFE tape on all the joints and use cam locks to get the best flow and your good.
