Pull the bypass stem on the rear of the water softener to the bypass position. The bypass stem is on the house pipe connections going to the softener and slides left or right. Unplug the power cord from the wall outlet.
Lift and remove the cover on the softener. Remove the cover from the top of the brine well. The brine well is the large tube inside the softener that houses the brine valve assembly. The cover lifts off by hand.
Remove the nut securing the brine valve tubing to the venturi housing with a wrench. The venturi housing is the assembly near the rear of the softener and has a dome cap on one side. The tubing from the brine valve connects to the left of the housing.
Grab the brine assembly at the top and pull it straight out of the brine well. Tip the brine valve upside down in the bathtub or outside to remove the water inside the valve assembly.
