water softener valve s and function
WATER SOFTENER VALVE’S AND FUNCTION

The five cycle softening process.

Service. Raw water passes “down flow” through the resin bed.

Backwash. The resin bed is fluidized loosening the resin particles and removing suspended matter captured during the service cycle.

Brine Draw. A brine solution is applied “down flow” to the resin bed removing the hardness ions from the resin matrix.

Slow Rinse. The brine is rinsed from the resin bed at a low flow rate to reduce water use.

Fast Rinse. The resin is rinsed at a higher rate to remove all brine from the bed. After the fast rinse cycle, the softener is on Standby until returned to Service.

VALVE FUNCTION
  • Service
  • During the service cycle, the raw water enters the top of the tank, flows through the inlet flow distributor, passes through the resin bed and exits the tank through the gravel support bed and under drain system.

VALVE FUNCTION
  • Backwash
  • In backwash, the raw water enters the bottom of the bed through the under drain system and exits through the top of the tank to waste. Backwash is up flow and the resin bed is fluidized.
  • (10-12 Minutes)

VALVE FUNCTION

  • Brining
  • The resin has limited exchange capacity, which must be restored periodically through a process known as regeneration.
  • (15-25 Minutes)

VALVE FUNCTION

  • Slow Rinse
  • After the brine valve has closed, fresh water continues to flow through the eductor. Since the brine valve is closed, no brine is drawn and the flow rate is constrained by the eductor. This continues until the softener sequences to the next cycle, fast rinse.
  • (40 Minute min.)

VALVE FUNCTION

  • Fast Rinse
  • The fast rinse cycle is a service to waste cycle. The inlet water flows through the service piping and thru the bed but rather than being routed to the softener outlet, it is routed to drain or waste.
  • (10-15 Minutes)
