NEW QUESTIONS Rodi

Ok so i know its a little extra but its worth the extra money to get this one 75 GPD RO/DI 5 Stage *PLUS* System - English

Its comes with a pressure gauge, flush kit, dual tds meter, and also a auto shut off switch so that way you can set the rodi unit with a float switch so that it will fill up on its own as needed and you wont have to worry about it

 

How long does it take for the system to pump 10 gallons? it said it has like a rejection rate or something?

 

BUMP for last question

 

Too expensive for me...I was looking to spend less then 150.

 

I know somebody knows the answer!

 

i have a 150gpd 6 stage system running at 60 psi and it takes about an hour to pump 10 gallons.. i have a 4:1 ratio(4 gallons of dirty water to get 1 gallon of 0tds rodi water)

 

Thanks, Saints fan! Does the type of sink determine the pounds per sq inch you get or is it just your home's water supply?

 

Dow Filmtec RO membranes are rated to produce their 75 GPD at 50 psi incoming pressure and 77 degree F water temperature. If either or both are lower it will take longer and if either or both are higher then it will be quicker. 75 GPD is about 3 gallons per hour (75/24= 3.125 GPH).
If you know your pressure and temperature or if you want to get a good idea of how much you can expect take a look at the calculator at the top of the page here:

While you are there take a look at their 75 GPD Premium system (BFS-161) for only $169, its a little better system than the Plus you are looking at for less money.

 

Thanks for the great info, AZ! But, how do I figure out the PSI?

 

Get a cheap gauge from home depot or lowes
