View Full Version : RO systems are NOT created equal

We sometimes hear, especially from people new to RO and RODI systems, something along the lines of "all RO systems are alike - its just the filters in the system that vary."

This makes us cringe everytime we hear it - nothing could be further from the truth.

Here's a perfect example. In the pic below you'll see an RO system from what many reefers would consider a well known company (that shall go unidentified here), and... it is plumbed incorrectly, or least in a way that is much less than ideal.

Experienced RODI users will understand that the primary component in the system that is sensitive to water pressure is the RO membrane. If a system has only one pressure gauge, the critical reading is the pressure that reaches the membrane. The manufacturer in the pic below has the pressure gauge reading BEFORE all three prefilters. With that system, you could have all three prefilters 100% clogged, and the pressure gauge would still be telling you everything is just fine and dandy. A person who was new to RO systems who bought the system would have no clue the system has such a fundamental configuration fault.

We've seen many many other configuration errors on systems over the years, as well as low quality parts and construction. So next time you hear someone say "all RO systems are alike," - it is absolutely not true.
