ro/di water

What kind of system do most of you use. And how often do you have to change the filters

 

I use a Spectrapure. 6 months on the prefilter and carbon, nearly never on the RO membrane, and the DI is changed whenever you get 1+ TDS output.

 

I also use Spectrapure. Their quality and cost of ownership cannot be beat, thats probably why they have been around for over 25 years.

I've got a 75 gpd from BRS. BRS has a good mix of price and positive reviews.

I gave Spectrapure some serious thought because of all the extremely positive reviews. However, the Spectrapure website doesn't tell you what comes with their RO/DI unit. Also their shipping was about 30 dollars.

 

Nonsense, the only place they don't tell you that information is on the sale page. Go look on their full website, and they explain everything in excruciating detail.

The shipping is $30 because the MaxCap I got was about 20-25 pounds, and about 2 foot x 1.5 foot x 2 foot. It's a huge, heavy box, and the unit needs to be packaged properly to avoid damage.

 

OK here is the question then what happens if you set up your tank start your cycle then in a couple of months you get your ro/di system is it to late and you have problems.

 

You could very well have problems. If you don't get an RODI off the bat, at least get RODI water from a LFS, and make sure you check their TDS meter.

 

If the sale page stated whether the RO/DI unit came with accessories like a tds meter, pressure gauge, etc. Than I would have no complaints. The fact that you have to navigate away from the sale page to find out what you're buying is awkward.

IMO 30.00 is high for shipping.

 

Ok i am taking my water to be tested by the culligan man -you know the water guys how close to .000 is save or are we talking absolute .000

 

All the shipping quotes I have seen on the forums was $18 for the CSP-DI or ProPlus. The MaxCap is a much larger and heavier system so it would obviously be more.
Spectrapure has the most detailed information available anywhere, no other manufacturere or vendor has anything like they offer.

When you buy a RO/DI you should always do some research, not just look at a sale flyer or single page. The information is all there.

I doubt Culligan can give you 0 TDS and if they do it will be very expensive. Don't accept anything less than 0 TDS and at no more than a nickel a gallon final cost because that about the maximum a RO/DI costs to make water including the water and sewer rates and filter replacements.
