What is RO filtered water?
Reverse Osmosis (RO) is a water treatment process that removes contaminants from water by using pressure to force water molecules through a semipermeable membrane. During this process, the contaminants are filtered out and flushed away, leaving clean, delicious drinking water.
Why is my reverse osmosis constantly draining?
The reverse osmosis system shuts down when tank pressure reaches 2/3 of supply line pressure and the ASO valve closes. Constant water running to the drain simply means that the ASO is not shutting off. The ASO operates if the membrane, flow restrictor, tank, and check valve are all performing properly.
Do dishwashers have a built in air gap?
Dishwashers require a way to funnel in clean water and drain out dirty water.
