Duff0712 Posted August 27, 2014 Report Share Posted August 27, 2014 So I finally got my RO/DI Unit set up on my sink and it working fine (by my standards, its my first time using one), however my PSI reading is at around 40-43 range and from everywhere on the internet, and even the manual, I am being told 65 is where I should be aiming for. Should I get a booster? I don't really want to spend anymore money at the moment, but if getting a booster for it is really going to produce Ro/DI water quicker and make use of my membrane more efficiently I guess I'll bite my tongue and get it. Wanted to ask you guys! The one I am currently looking at is this guy http://www.bulkreefsupply.com/1-4-aquatec-8800-booster-pump-1.html if you guys think I should, would this be a good one to get? My RO/DI is rated at 100 GPD. Quote Link to comment Share on other sites More sharing options...
OblongShrimp Posted August 27, 2014 Report Share Posted August 27, 2014 Where are you measuring the PSI? Is it after the prefilters before the RO filter or is it before it enters your unit? I ask because as your prefilters get old and clogged your PSI will decrease. I would assume though since you just set it up it is probably a new unit right?

Duff0712 Posted August 27, 2014 Author Report Share Posted August 27, 2014 I have a inline psi reader hooked up to read it before water hits the first filter. And the unit is new yes. -Duffy Quote Link to comment Share on other sites More sharing options...
h4n Posted August 28, 2014 Report Share Posted August 28, 2014 If i remember correctly the high PSI for your water pressure makes it so you make more RO vs waste water. So lets say you have a 1:5 gallon ratio now the higher water pressure will bring it down to say 1:3 gal. So ya get one if you want to make more RO water quicker without wasting more water then needed. Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted August 28, 2014 Report Share Posted August 28, 2014 Plus, the lower water pressure, the more TDS left in the water. Quote Link to comment Share on other sites More sharing options...
h4n Posted August 28, 2014 Report Share Posted August 28, 2014 I think it still get filtered out with the Ro unit just not fast enough or effective. Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted August 28, 2014 Report Share Posted August 28, 2014 My water pressure is extremely low in this house. When I put it through the RO it takes about 3 hours for a 5g bucket, and winds up in the teens or low 20's after some use. Not perfect, but I won't go back to regular tap.

Duff0712 Posted August 28, 2014 Author Report Share Posted August 28, 2014 Hmm alright. After testing the ro/di water I'm getting 0 TDS and it takes about an hour or so to fill a 5g bucket. Albeit slowish but not worth 80 bucks to increase speed by that much. Thanks for the info guys -Duffy Quote Link to comment Share on other sites More sharing options...
Soothing Shrimp Posted August 28, 2014 Report Share Posted August 28, 2014 When I need ro, I just turn it on and let it run overnight into my Brute garbage can. That way it is ready when I need it. Quote Link to comment Share on other sites More sharing options...

h4n Posted August 28, 2014 Report Share Posted August 28, 2014 ya if you fill a 5g bucket in an hour I think your good to go without a booster save your $$ Quote Link to comment Share on other sites More sharing options...
