Water softener problem - advice?
Been reading here for a bit but now I have a dilemma and need some advice.
I use approx. 180 to 190gals a day and have a hardness of 8, no iron or otherwise. I purchased a FLeck 7000 with 1.25cf (40k?) Nelson Resin in February. About 2 months later I talked with a technician from Fleck and changed out the BLFC and injector assembly to that of a 24,000 grain system for salt savings and efficiency. I have set the unit to C 18000 @H 8 for 2250gals, .25gpm BLFC set at 16mins. all the rest are consistent with what I read here.
I had override set at 11 days and only one time did the usage require regen the rest of the time it was override. About 6 weeks ago I set the override to 12days. The other night I noticed the gals down to 33 and it did regenerate on the days because I use no safety factor. However this time, the first time, I noticed that the slippery feel of soaps/detergents is not there. Usually the days following a regen I notice my face is as slippery as heck as I rinse in the shower, not this time. So I decided to manually regen the next night. My main test ( I know it is not the professional way) is to use a bar of Ivory soap in the garage sink, if the water is soft the slippery feel is never gone until I dry my hands. Not this time! even after 2 regens. I believe my resin is discharged and needs a jolt.
Here's what is in my head: I use the formula 2.2 lbs of salt is dissolved into 1 gallon water...?? I rebrine with 4 gals - 8.8lbs. All the charts I had read state this should be enough salt for 24000. However tonight I looked at Nelson's site and they say for 1.0 CF resin 15lbs of salt is needed for 33,000 grains. Converting to my needs this would put me at 8lbs at 16500 and not 18000. Am I correct in my calculations here - I came up short? Also would I gain by purchasing 1.0 cf Purolite C100 and changing out the Nelson?(notice I went down from 1.25cf). My tank is 10X44.
any advice is greatly appreciated!
