I have installed a softener (40,000 grains) at tha mains of a nightclub. Although the water softens without problem (I use a HANNA KIT with drops and the hardness falls from 300 ppm to 40 ppm) my client gets a bitter taste at his drinking water. This did not happen for the first month after installation. Taste became bitter after this month of function.
Please note that I have set as follows my softener: 20 mins backwash, 30 mins brine, 20 mins refill). My device is Water Softener (CSIII H 1035) from Shanghai Canature Environmental Products Co.,Ltd. (http://www.ecvv.com/product/1793575.html). Unfortunately I do not get any answers from them... I have also installed a sediment big blue 20" filter before water enters the softener and a CTO big blue 20" filter after the softening of the water.
PLEASE ADVICE AND THANK YOU VERY MUCH IN ADVANCE.
