Guys... you should note that I don't suggest using the flexible SS lines as y'all do but... the 7000 keeps most residential size softeners farther away from the wall than other valves. Plus the fact that this 2.0 cuft softener does not need a 1.25" valve.
JS you input the actual number of lbs in the Clack control valve. I.E. for it to use 4 lbs/regeneration, you use the down arrow button to change the factory default setting of 9.5 lbs to 4 lbs. If you want 4lbs/cuft, then do the math for the number of cuft of resin you have times 4 and change the default 9.5 lbs to that number.
