Watts premier 4-Stage Reverse Osmosis System Review

 

Features of Watts Premier 4-Stage Reverse Osmosis System

Efficiency

The efficiency of the system is determined by the water waste ratio.

Water waste is an unavoidable part of the reverse osmosis filtration process. You can’t expect purified water from a Reverse osmosis system without some wastage. Although, the ratio of water waste varies from system to system. It also depends on the feed water pressure & temperature.

For the Watts premier 4-stage RO-system, we don’t have any authorized water waste ratio from the manufacturer. But the tests have shown that this system waste between 3-4 gallons for every gallon of purified water produced.

Water Production

Water Production may change due to the feed water pressure and water temperature. But, at the standard pressure and temperature, it is capable of producing 50 gallons per day.

Which makes it an ideal under-sink water filter for small and medium-sized families. This water production may not be enough for larger-sized families. You can check out the APEC RO-90 filter which is the best water filter for larger families.

With a water pressure of 40 psi it works effectively, if the pressure is below 40 psi it can reduce the performance of your under-sink RO system. Thankfully 40psi is the standard pressure that most households have.  So, you don’t have to take too much notice of this.

Filtration Process

Watts premier has the 4-stages of the filtration process. It removes 99.9% of contaminants from the feed water.

All 4 stages of the process have their own task to do.

Check what each stage of the filter foes below:

Stage 1: This stage ensures that the water is free from rust & dust. In short, this stage has the job of removing all the sediments and particles from water that has an impact on the color and taste of the water.

Stage 2: There are many particles that cause an unpleasant odor in your water and affect the taste of water making it less desirable, and in some cases, undrinkable. Stage 2 works to remove all these particles from water.

“Filters at stages 1 and 2 are known as pre-filters. Their performance has a direct impact on how effective the stage 3 filter RO-Membrane filter is.”

Stage 3: At this stage, the reverse osmosis membrane gets into action. It removes up to 99% of all possible harmful contaminants and TDS from the water. The contaminants include arsenic, viruses, fluoride, cadmium, bacteria & many more. A vast reduction in nitrites and nitrates also occurs during this stage.

“The filters that work after an RO-Membrane are called Post filters. They give final touches to water treatment

Stage 4: This stage ensures that you are drinking completely pure water. When you turn on the faucet, this stage of the process eliminates all the remaining microscopic particles and contaminants that previous stages may have not been able to filter out. 

Installation

We have reviewed only convenient, trustworthy, durable, and well-performed RO systems. There are many Osmosis water filters that are really difficult to install, causing nothing but frustration and headaches, when all you want is simple filtered water from your tap. 

 But it is not the case with Watts Premier RO pure system, because the mounting, and installation of this filtration system are straight-forward. You are not going to need professional assistance for the installation of the Watts Premier Filter. 

Instructions manual

If you are new to the reverse osmosis system you can use the Instructions manual that comes along with the system. The instructions Manual is Concise, easy to understand, and well-written.

Before starting the process you should spend a little time reading the instructions manual, to ensure you do not make an error and damage the system.

Faucet installation

Air Gap faucet installation is the only step in your installation process that may take a little bit more effort. The faucet needs to be installed in your kitchen sink before having purified water. The faucet installation requires a hole of 1 ¼” diameter in your sink.

Your installation process might be more effortless if your sink already has a hole. Otherwise, you have to drill the hole to set up the faucet. Drilling the hole is not that difficult, but it is the one part of the installation that intimidates some people and can make the process a little longer for those who are not used to working with power tools.


 

Filter replacement

Watts premier Filter replacement is essential for keeping the performance at the maximum level. If you have done the installation of the system by yourself, then the filter replacement will not be an issue for you.

The system is more suitable for medium and small-sized families with municipal water and reasonable water pressure.
