Flow of clean RODI water too slow??

I've recently got this RODI system from puritech https://puritech.co.za/product/reve...ing&utm_medium=cpc&utm_campaign=Shopping+Feed, I've also purchased an additional filter chamber for DI resin. So my setup currently includes a sediment filter > carbon block, 75 GPD membrane > DI resin chamber (see pictures included). From what I can tell, there is no flush valve on any sort . It is plumbed into the same pipe that feeds water to the geyser. Currently TDS readings are around 0,56 ppm after the DI resin chamber..... everything is brand new and freshly installed. From what I can see everything seems to be installed correctly, even tho my TDS reading should be closer to 0 ppm after the DI resin chamber.


I wanted to know if my clean water is supposed to be coming out so slowly whilst my waste water gushes out? Do I perhaps need a booster pump? Currently the system can fill a 1,5 litre jug in around 13 minutes.

Welcome to the joys of passive RODI. I hope you have a garden.
