A Suds saver model has a solenoid valve with 3 ports. One for drain in and two for drain out, one drain out is for suds drain and the other drain out is for the rinse drain. When the machine drains the wash water the timer tells the valve to drain via the suds drain hose which is placed in a laundry tub and extends down to the bottom of the tub. The tub drain must of course have a stopper so the tub holds the wash water. On rinse the timer tells the valve to drain from the drain hose which is placed in a stand pipe or in the case of two laundry tubs, in the other tub which of course is allowed to drain. When one is ready to wash the next load the timer is put on "Suds" and the washer will suck the water from the wash tub back into the machine to be used again.
