Fits the bottom of the Grainfather G30 perfectly. Helps to prevent clogging of the pump screen even with huge hop charges. A whirlpool helps maintain pump flow during chilling.
JW's Note: This will trap heat and make your G30 think it's hotter than it is. Make sure to run the pump during the mash and sparge and verify the unit is boiling before starting the boil timer. One of the best upgrades I've done.
