Does 10% resin require impact softening capacity and does it require a special screen

I just purchased my first ever water softener (Watts with Clack WS1 with 1.5 cu. ft. of resin rated for 45,000 grains using the standard 8% resin). The dealer who sold me the Watts system was able to have Watts swap out the standard 8% resin and use 10% resin free of charge. Does the change in resin change the total grains the 1.5 cu. ft. can treat? If yes, is there a way to determine what the new total grain capacity is?

Does the change from 8% to 10% resin require a different type of riser screen be used within the resin tank?

Thank you in advance for any insight you can provide.

8 and 10 percent crosslink have similar capacities and use the same flow control as long as they are standard resin types.

The actual unit capacity is much less than claimed. It should be set up according to industry standards. 20,000 grains per cu. ft. if the system is regenerated with 6 pounds of salt per cu. ft. or 30,000 grains capacity when regenerated with 9 pounds total for your system.

The company who is installing it should take care of this part for you.

Clack valve based systems must be installed by the company selling it. I assume they are installing it, programming it etc. for you...

Thank you for the prompt reply and helpful information. The independent dealer who sold me the Watts system is setting up the system, however, he is only inputting the basics such as setting time, inputting hardness info, regen time of day. etc. Watts told me they preset set all of their Clack valves to a capacity of 24,000 grains and 6 lb of salt per regen. I will ask the installer to change the settings to 30,000 grain capacity and 9 lb of salt per regen.

6 pounds would be 20K, not 24K. 8 pounds is 24 K capacity.

My sytem is 1.5 cu. ft of resin advertised as having a 45,000 grain capacity. I thought your guidance was to program for a capacity of 30,000 grains and 9 lbs per regen?

Correct, 1.5 Cu. Ft. at 20K per cu. ft would be 30K capacity, the salt would be 6 pounds per cu. ft, or 9 pounds total.

It got a little lost in translation.
