Does anyone know with the Aquatic 8800 booster pump and the 6 stage RO/DI unit from Bulk Reef Supply, does the pressure switch go on the blue line between the RO unit and the DI unit or after the DI unit? The instructions say to put it on the blue line after the RO unit, but it doesn't seem to shut off when the float switch is elevated.
Thank you.
Thank you.
