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

Tap the main BEOFRE the meter! :twised:

Oh believe me I thought long and hard about that lol

I've been studying the picture of your Ro/di.Like you said, it is hard to trace the lines because they are behind the unit. Is it possible that the auto shutoff valve is hooked up backwards? I have attached pictures of my unit, I hope this is of some help.

Problem solved!!!! http://s1359.photobucket.com/user/St...tml?sort=3&o=0
