Areas that have a high mineral content in the water may need a water softener. Using a softener removes minerals from the water that may cause deposits on your water fixtures, and may improve the taste of the water as well. Without regular servicing the softener will likely have problems, including low water pressure. Have your water softener professionally serviced once a year, or perform the maintenance indicated in your owner's manual. To increase water pressure in the water softener tanks, you will need to restore the resin bed.
Unplug the unit from the wall. Close the inlet and outlet valves on the tank by turning the water control knobs.
Insert a screwdriver into the backwash control for the tanks and backwash the system. This relieves pressure from the tanks.
Unscrew the valve at the top of the tank. Siphon water that is on top of the resin out of the tank.
Vacuum the resin off the top of the tank using a wet/dry vacuum.
Add 1/4 to 1/8 inch gravel to the bottom of the tank until there is 3 to 4 inches.
Reinstall the valve. Open the inlet bypass valve and fill the tank. Watch the water that flows out of the drain until it turns clear, then close the valve.
Restore the tank to the regular flow position.
