Repair guides for water softeners
The venturi valve in your water softener draws brine water from the salt tank to the resin tank for regeneration. Follow these steps to replace a damaged venturi.
The rotor position switch detects the position of the valve rotor. If the rotor position switch fails, follow these steps to replace it in about half an hour.
The timer is the control board you use to program the water softener. If the timer isn’t accepting commands when you push the buttons or if the display won’t power up, replace the timer.
