I have a 300 gpd streamline system, I have noticed my production has become slower, I have low water pressure and use a booster pump the pump is about a year old and doesn't get used too often about 30 hours a week, I have been timing my waste and pure and the difference is a lot half a pint of pure is 30 seconds and the waste is 10 seconds, I would say it takes about 25-30 hours to fill my 1000 litres ibc and the resin will be on about 2
003 when it's done, does this sound right, I have changed all filters, my di is the little 750 one
