Kent Marine Maxxima 24 GPD RO/DI System any good?!

i found one of these on craigslist only use for a few months he wants 75 dollars for it is it a good r/o unit? do you think its a good deal?

 

bump anyone?

 

I would pass. That is a low GPD.

 

ya lol but im working with a 10 gpd now lol so it would be nice for me lol but thanks for input

 

24 GPD is painfully slow, in reality its about 2-3 quarts an hour at 65 psi and 77 degree water temperature. I doubt you have 77 degree water and probably more like 50 psi at the tap if your in an average water system.

You can just about guarantee it needs a new prefilter, carbon block and probably DI resin too if its been used a few months. A TDS meter will tell for the membrane and DI but the prefilter and carbon should be changed at 6 month intervals regardless of usage or final TDS. Now you are approaching $100-$125 and probably still don't have the necessary TDS meter or pressure gauge to determines its condition. That's another $40 or more and you still have a 24 GPD system.

I would forego buying used unless you know the person and the condition of the unit. Used ends up costing more than new in many cases.

Take a look at systems like the ProPlus here for $149:

or the 75 GPD Premium here for $169:

Both include TDS meters, pressure gauges, 75-90 GPD RO membranes, new prefilters and carbons, full size vertical DI filters with 20 oz of fresh resin etc.

 

I am going to post my old Spectrapure 50-60 GPD CSP RO/DI in the classified section soon for about $50 probably - it needs new filters - but it might interest you if in California.

 

All you have to do is add a 100GPD membrane if you want that much water all you have to do in change the waste water re stricter on the outlet its a little temperature sensitive capillarity that slips into the 1/4 drain like 3.00 or so . And you will need new filters anyways

 

The cost of a new membrane, flow restrictor, filters and DI is almost as much as a new unit. You still don't have a pressure gauge or TDS meter though so are you ahead or not?

I would never recommend a 100 GPD Dow Filmtec RO membrane to anyone, its a GE membrane thats a different story but its still only equal to a Dow Filmtec 75 GPD which is the industry standard. Both do 75 GPD at 50 psi, 90 GPD at 60 psi and 100 GPD at 65 psi which is how GE rates theirs, problem is most of us don't have 65 psi at the tap so 75 GPD is more realistic.

 

thanks to all
Matt unfortunatly im not in cali i wish lol
azdesertrat i appreciate the posts i think im gonna pass for now
