I have an RO (Reversed Osmosis ) system under the sink for drinking. It has a 2 gallon tank reservoir with an ASO to shut the input water off when the reservoir tank is full. I replaced the ASO recently but I notice the RO waste water keeps running. If I manually close the valve to the reservoir tank then the RO waste water stops running after a few seconds; if then I open the valve to the reservoir then the RO waste water will not come out any more until I drain some of the water from the reservoir tank. It feels like the ASO will not be strong enough to shut the water input by it self. Defective ASO?
Is there a better quality ASO I can buy ?
Thank you
