Pelican PRO-RO 6-Stage Undersink Reverse Osmosis System

Pelican PRO-RO 6-Stage Reverse Osmosis System

  •    Price: $$$
  •    Flow Rate: 15 gpd
  •    Filt. Capacity:
  •    NSF Cert.: 58
  •    Warranty: 1 Year

The Pelican PRO-RO 6-stage reverse osmosis system delivers pure and refreshing drinking water free from harmful chemicals and other contaminants straight from your kitchen tap.

It also eliminates any unpleasant odors allowing you to fully enjoy the food, coffee and tea that you cook.

Let’s take a closer look at how the filtration works:

  • First, water runs through 4 different filter stages housed in a single cartridge. The cartridge combines a 20-micron sediment pre-filter with a granular activated carbon (GAC) pre-filter, followed by the actual reverse osmosis membrane and a second GAC (post-)filter stage. At this point, the water is stored in the system tank.
  • When water is drawn from the tank, it runs through the final 2 filtration and enhancement stages. First an activated carbon polishing filter removes any residual taste. Then a calcite remineralizing filter comes into play that enriches your water with healthy calcium & magnesium.

This process has earned the Pelican PRO-RO 6-stage a WQA (Water Quality Association) certification for NSF/ANSI Standard 58.

Average reduction rates for substances specified on the performance data sheet include:

  • Arsenic 5 – 99.0%
  • Cadmium – 98.3%
  • Chromium 6 – 98.3%
  • Chromium 3 – 99.0%
  • Fluoride – 93.8%
  • Lead – 96.8%
  • Radium 226/228 – 98.8%
  • Turbidity – 98.7%
  • TDS (Total Dissolved Solids) – 93.1%

In order to achieve similar results, feed water pressure to the unit must not be lower than 40 psi and no greater than 80 psi.

Speaking of pressure, the system can produce up to 15 gallons of purified per day at 50 psi and 750 mg/l TDS at 77 °F.

Under these conditions the recovery rate is 26.76%, meaning that 3 gallons of water will go down your drain for every gallon of filtered water. This sounds like a lot of wastewater, and it is, but compared to the average RO system, above 25% recovery is actually quite good.

Pros

Thanks to its compact design the PRO-RO will leave plenty of room for your cleaning products in the cabinet under your kitchen sink. This is also what makes it great for smaller apartments and condos.

Above that, you can select from 3 different faucet finishes to match your kitchen decor: Chrome, brushed nickel & oil-rubbed bronze.

You also get a 1-year limited warranty.

Did we mention that the system + membranes are made in the USA?

Free Water Test

As an additional service Pelican offers to analyze a sample of your water every 6 months for free. The diagnosis helps to make sure that your system and the RO membrane in particular is functioning as intended.

To send a sample, fill one container with ½ cup of plain tap water and another one with ½ cup of RO filtered water. Label each sample and send them to:

Pelican Water Systems
3060 Performance Circle, Suite 2
Deland, FL 32724

The company will test both and contact you with the results.

Pelican PRO-RO 6-Stage Under Sink Reverse Osmosis System

System Installation

In order to set up this under counter system yourself you should be familiar with standard sink plumbing and common hand and power tools.

Probably the hardest part for most people is drilling the hole through their kitchen countertop and the drain line.

Fortunately, Pelican’s instructions and videos are more than helpful. If you still get stuck and have no idea what to do next, make sure to contact the knowledgeable customer service.

Pro Tips:

  • Running the black and white tubing under warm water for a couple of minutes will soften them and thus allow for easier installation on the air-gap barbs.
  • For the tubing, avoid low spots and loops.
  • Properly flush the system before first use as per manufacturer instructions.

Below is part 1 of a 3-part installation video series provided by Pelican Water Systems. Part 2 and 3 are also available on YouTube:

Parts List

  • Water storage tank
  • Tank valve
  • Air-gap faucet
  • ⅜” and ¼” color-coded tubing
  • Drain connection assembly
  • Quick connect fittings
  • Feed valve assembly (with adapter and shut-off valve)
  • 4-stage filter
  • Remineralizing post-filter cartridge

Filter/Membrane Replacements

No tools are needed to change the 4-stage filter cartridge: Simply remove the cover to get access. The same goes for the carbon/mineral post-filter.

How often do you have to change the two components?

  • 4-stage cartridge: Must be replaced about every 18 months or when TDS reduction falls below 85%
  • GAC/calcite post-filter: Must be replaced every 6 to 12 months

Of course these are only rough guideline. Exact lifetimes depend on your water usage and quality.

Annual cost? Expensive compared to other RO systems.

Cons

The bad news is that the Pelican PRO-RO reverse osmosis system is much more expensive than most other RO under sink units.

Also, some customers reportedly struggled with a leaking faucet. According to Pelican, this might have to do with a malfunctioning (clogged) drain line which is not necessarily a manufacturing error.

Our Verdict

Pelican’s PRO-RO reverse osmosis system provides great tasting drinking water and runs without problems – a joy to have at home. Most customers are completely happy with their purchase and highly recommend the product.

Taking into account the high initial price and increased cost for maintenance, we rate it with 3.5 stars.
