I just purchased a house with a Fleck 7000 system and have lived there for just over 2 months and noticed we have not consumed any salt. I’ve manually run several regenerations, confirmed all settings (H-18, all the rest set at default), monitored the system cycle and noticed the water level in the brine tank is just a few inches and does not rise above the metal grid at the bottom of the brine tank or near the float on the check valve. I manually added water and ran regeneration and it consumed salt, and I verified its adding back water, but it looks like I’d need to increase the refill time from the default 10 min. to 20+ to get the water level up past the grid. Should I change the refill time, or is something else wrong. Water hardness is 18, I’m not sure of the size of the system; (it’s a chrome cylinder about 4 ft. tall). We’re a family of four and have a pool, so we’re consuming allot of water.
