So I believe it has been hooked up alright but I think the low water pressure may be the culprit  I am going to tap into my main 3/4 inch line and run the 1/4" off of that ,if that boosts the pressure then i will by all new filters and a new di , if it still sits low then I am going to spring for a new unit one with a booster pump  and tds meter all built in ...... I hope the new line placement works
