Hey Ray , 
I have a question regarding the booster pump. 
I have a spectrapure max cap 90 - From you 
I currently have it set with a 4/1 waste ration with the restrictor thing that comes with the unit. 
When  installing this booster pump do you need to redo the rejection ratio with a new flow restrictor ?
The description of the pump says you can reduce waste rejection to what ratio ?
thanks
