Problem scenario
Your AquaSana drinking water filtration system (that does reverse osmosis) is making a loud noise. It makes a moaning or honking sound that is quite loud as the tank fills up. It did not used to do this. What should you do?
Possible solution
You need a new RO flow restrictor. AquaSana can refer to this as item #130 or material #100236736. If the skinny white/transparent tube is missing from the black plastic piece of this RO restrictor, there can be a loud noise to the RO device.
