The refill rate is critical in setting the system correctly. If you remove the gray clip from the valvee brine line fitting, pul out the brine line, and look inside. You will see in tiny writing, either
This would be the BLFC flow rate. it should be either 123, or 25. If it is 50, it is wrong. The injector should also be checked, remove the red clip from the top of the valve (be sure to depressurise the valve, and push the cap into the valve about 1/8" before attempting to remove the red clip or you will break the clip), remove the cap, and inspect the injector. Let us know what color the injector is. Once you have this basic information, we can help you properly. Many companies are unaware how to set up a softener valve correctly and simply ship the valves as they come from the manufacturer instead of adjusting the valve properly. This can lead to a very inefficient softener.
I have attached a picture of the BLFC. These are the numbers you will be looing for inside.
