Cleaning March pumps

BB- that looks good enough for me- I’ll stick with the PBW (as I just stocked up on it recently), but follow that with some clean hot water to rinse out any residual before storage. Thanks again to all for the responses.

Same here, but my pump DOES move post boil wort while chilling and also I pump it to my fermenter. No contamination after many years and hundreds of gallons brewed. I do run hot wort through it for about 3 minutes at flame out before I turn on the chill water.

Yeah, give it a good hot water rinse after the PBW. I hook my CFC to one of my pumps and circulate the solution of PBW through both. Then give them a good rinse.

I also run hot PBW through my pumps and whole system regularly and the pumps and seals are like new after several years. Everything gets rinsed well afterwards no matter what.
