Had a missing o-ring in one of the DI canisters. BRS customer service quickly sent one out to get me going. Unit works great and is making water with 0 TDS as described!!

Thanks to the great customer service at BRS the first one I got had some leaks I called BRS and they shipped another one right out no questions asked. Got it the next day and it has been great ever since.

I searched all over for a complete RO/DI system for city water treated with chloramines. I narrowed my choices down to this unit and a Spectra Pure system. I'm so glad I selected this one as it has been so easy to use and set up. I had been using a 4 stage unit from Costco but have reduced it to serving as a filtration unit for drinking water only. It only would last a couple of months before I had to replace filters due to TDS slowly increasing weekly.

Interestingly, the Costco unit would reduce the TDS of our (TDS 255) tap water to about 4-6 TDS after replacing all the filters and membrane. It would stay there for a few weeks and then creep up to about a TDS of 11 or so before I would replace the required filters. The output of the BRS unit before hitting the DI resin consistently has a TDS of only 2-3 using the same meter and hasn't changed for 4 months. Nice

With the BRS unit installation was simple. The on board TDS meters and clear canisters let you know which media or filters need replacing. This saves so much guess work (and money). The one problem was that several of the fittings needed tightening and the unit leaked from them when first installed. I had read from several reviews that leaks can occasionally can be a problem with these. I'm a big fan of not fixing what isn't broken so I initially installed it for easy removal in the event of issues. Sure enough, mine leaked from a few inaccessible fittings. I had to remove and disassemble the unit to tighten them to get at the trouble makers. I was initially disappointed but it only took about 15 minutes for the whole process so it's really no big deal.

All in all this would be a five star purchase if not for the minor annoyance of doing a fiddling with it a bit. If I had to do it over again I'd still buy this unit.

I received this system 2 days ago and couldn't be happier. It's running at 3 to 1 (waste to product, which might increase with time ) at 50 psi. I haven't checked the tds coming in to the system yet, but I worked for the local water company and it runs about 200 tds. Going in the di unit is around 5-7, coming out is 0. The construction of the system is very durable and with the 2 stage o-ring on every connection assures a leak proof system!! IMO, you can't go wrong with this system!!!!

Just got my unit last night. (Valentines day and wife was not happy).

Couldn't resist setting it up and it litteraly took longer to unbox everything than it did to hook it up.

TDS going into the first stage was around 900. Zero after coming out of the last DI canister. Going into the first DI canister was fairly consistent at around 10-12.

Super Happy with this and will only buy from BRS due to their AWESOME customer service!!!!!!

This is great unit would recommend to anyone looking I buy. This would have have 5 stars from me BUT my only complaint is the monitor is held on by Velcro. And it falls off all the time this piece should have a slot or hole in the back for mounting to the wall. Thanks BRS for good units.

Very happy with the product and more so with BRS customer support. The RO/DI had a small leak when I first installed it. I called BRS customer support and they gave me the option of sending me a replacement part or sending me a new unit. The new unit came in within a few days and no problems whatsoever since then. Great value.

I own the 5 stage plus syetm and just recently bought the 6 stage deluxe. It is a great value and the system is worth every penny. Wish I bought this system first. Awesome stuff.

Setup is simple. Solid construction. Would definitely recommend this product.

My city just switched to chloramines and now basically the whole reef club owns one of these systems. I could smell the ammonia in my holding tank and my test kit showed ammonia the water coming out of my RO. This unit solved both issues completely. build quality is also on a different level form the one my LFS sold me years ago.

I love the attention to detail that went into this system. It has a flush for both the membrane and catalytic carbon stage. The pressure gauge, TDS meter and volumizer are connected and configured just right. The instructions are great, too, well written and telling you exactly what you need to know.

But holy leaky leakstorm, Batman!

I'm glad I set it up in my concrete basement over the drain first. All three elbow connectors on the main unit were leaky. I've managed to fix one and almost fix another by just tightening them, but the third is positioned such that I'll need to take a canister off the mounting bracket. I'm still not sure whether I can fix it or will just need to send it back.

Too bad...there's so much to like!
