Preparations

Make sure that you have adequate space under your kitchen skin to allot a filter module and tank.

Once you have your RO purifier delivered, cross-check all the components, check if they fit in their desired locations like pipes, etc, so that you will get an idea about adjustments prior to installing the RO.

Required Tools

Plumbing Tools

Get ready with all the tools before installing the RO; this will not only save you a ton of time but also a lot of frustration.

  • Installation Manual
  • RO Module
  • RO Membrane
  • Water Storage Tank
  • Filter Cartridges
  • Faucet
  • Installation Kit
  • Power Drill
  • Screw Driver
  • Wrench
  • Knife
  • Teflon Tape
  • Drill Bit
  • Cutter
  • Towel

Now that you are ready with all the tools, let’s start installing the RO.

Faucet/Tap Installation

The first step towards the installation is installing the Faucet, which will provide you with great tasting, clean drinking water.

For starters, you will have to figure out where you are going to install it; unless you have an extra hole in your skin, you will have to drill one. Make sure to drill on a flat area for better convenience, plus it should be positioned correctly.

Note:- Depending on your material. You might need a particular type of drill bit.

Once you have dealt with the hole, put the faucet and secure it with a hex nut and washer. After that, attach the fitting and tighten it with a wrench.

Felicitations, you have just finished one of the most challenging tasks.

Drain Saddle Installation

The drain saddle or otherwise known as drain line adapter is responsible for the connection of drainage under the sink for RO WasteWater.

Before you start drilling, make sure that the drain saddle is placed far away from garbage disposal or dishwasher discharge if you have a dishwasher. This way, it will protect your RO water purifier from contamination and forestall clogging as well as obnoxious odors.

Moreover, we would suggest keeping it at least 6 inches above the p-trap.

Now you can drill a ¼ inches hole in the side or on the top of the drain line; make sure you don’t hole in the bottom. Next, align the camp hole and secure them with bolts; ensure that you are not over tightening the bolts.

Installing the Feed Valve

It’s time to connect the water line to the RO inlet feed valve.

Close the cold and hot water supply, and release the pressure by opening the respective outlets. Next, remove the tubing from the cold water valve. Install the new feed valve and tighten it with a wrench.

Now connect the water tubing to the installed feed valve and turn on the water supply.

Installing the Water Storage Tank

Now it’s time to place the water storage tank; if you don’t want to lose pressure, make sure to place it within 10 feet of the drinking water faucet.

Note:- When filled to the top, the tank can weigh more than 11KG depending on its size.

Around the threaded port, wrap about six Teflon tapes. After that, just screw it.

Mounting

When mounting the RO, keep in mind that you will have to replace the membrane and filters every once in a while. Therefore, to keep your maintenance days hassle-free, keep some sufficient space underneath the system.

Installing the Filters and Membrane

We are almost done, assemble the filter components and screw them properly.

Now insert the RO membrane and pre-filters into their respective housings by following the instructions we have mentioned.

  • Insert the filter by removing the filter housing and then screw them back; make sure to keep the O-rings in place — tighten the filter with the wrench.
  • As for the RO membrane, remove the housing cap and push the cylinder in; after that, put the cap back whilst ensuring that the O-rings are not disturbed.

Voila, you are done with the majority of the installation.

Start the System

Finally, it’s time to see if you succeeded or not. Check all the screwing and make sure that there is no leakage. Next, leave the outlet pipe for drainage into the sink.

Connect the plug to the electrical socket and run the system.

After around 15 minutes, the water will come out of the dispenser, and it might have a darkish color — don’t worry about that. It is just the carbon fines flushing out.

Next, fill the tank and let the first batch be the test-run, meaning don’t consume it and flush it out as soon as it fills.

Note:- Some manufacturers recommend flushing it 2 to 3 times before use.

Again fill the tank and enjoy the freshwater.
