How To Install A Reverse Osmosis System? – Complete Installation Guide


Many of the people who purchased a reverse osmosis system prefer to install by themselves. Yes, DIY is growingHow to install a reverse osmosis system? more popular, so we generally answer when people call and ask for How to install a reverse osmosis system for self-installation:

Installing a RO device should not be too hard or time consuming if you are handy and very mechanical.

How To Install A Reverse Osmosis System?

A reverse osmosis system provides one of the easiest ways to clean a house’s drinking water. This device extracts ions, molecules, and large sections from drinking water through a semi-permeable membrane. Reverse osmose provides numerous benefits over various kinds of filtration, since it offers the most dangerous pollutants – such heavy metals as lead – for four or five different filtering levels. A reverse osmosis system has very few components which make cleaning and maintenance very easy. And the EPA has been completely endorsed.

Reverse osmosis appears to be much stronger than the basic carbon black (charcoal-)filtration systems and far less costly than UV disinfectants which are the most efficient way to destroy pathogens compared to other point-of-use filtration systems. Where the water source is correctly treated with chlorine, a reverse osmosis method is the ideal option – although it is very difficult to produce one filtered gallon with up to three gallons.

Process of Installation

Although reverse osmosis systems can be built to treat all the housewater, it is common for a unit underneath the kitchen sink that supplies most of the water used for eating and drinking. The unit consists of four or five separate filtering containers, each filtering a different category, plus a storage tank containing filtered water. A spigot counter, separated from the house roller, provides clean water when needed.

Although the mechanics of the complex stuff of the reverse osmosis filtration device is very straightforward and requires only simple plumbing skills.

Tools you need

  • Measurement of tape
  • Driver Screw
  • Clamp adjustable
  • Hacksaw
  • Pliers for the channel lock

Materials you need

  • Filter package for reverse osmosis installation
  • Tea change (if needed)
  • Pipe-seal tape Plumber’s

Nine Easy Steps to Install the System

1. Plan to install

Make sure there is ample space under the kitchen sink for your tank and the filters before buying a reverse osmosis (RO) machine. Measure the available room. The majority of units are fitted with a tee connector that attaches the 1/2-inch cold water to the hose. Other RO units are using a 3/8″ flex line from the retractor. In this situation, an adapter tee above the valve may be used to supply the filter system with a source of water.

2. RO System Prepare

Remove the storage tank and filter elements and double. All the components can be fitted for testing if modifications are needed to the drain pipes or water pipes. If so, a plumber may assist in this job.

Controlled installation takes no room under the sink, but needs additional installation. Additional tubing for connecting the components may be needed.

3. Set the spigot down Sink

First, add the sink top spigot of the filter, so that you can get the lines underneath the counter until they become too crowded under the sink. Mount the RO spigot with hardware to the deck of the kitchen sink or counter top. The knockout for a sink sprayer may often be used for the spigot of the filter.

You should bore a new loop on the deck or countertop of the sink in the worst-case scenario to carry the spigot.

4. Place the tank

Install the tank connector before the RO tank is mounted under the sink. Using the plumber tube sealing tape on the threads of the nip tank, twist the spigot connector to the tank, so that cross-threading is not necessary. The connector must only be hand tight and easy to thread.

Place the tank underneath the sink. Place it underneath the sink top spigot, where possible.

5. Assembly of the Filter Mount

Remove the cover and mark the place of the hanger washers on the wall underneath the sink, to ensure the device is straight. This assembly must be at least 15 1/2 centimeters from the floor to allow ample space to remove filters for maintenance.

Place the washing machines in the marked position onto the wall and put the assembly on the washing machine.

6. Join the Line Water

Start with the water supply shut off before attaching 1/4 inches’ water pipe.

Depending on your situation, how you make this first connection can vary. Some filters feature a 1/2-inch adapter that functions well when a 1/2-inch hinge is added to the dishwasher. With a nut, ferrule and insert the green supply tube is attached to the adapter tee.

7. Link the other tubes

The layout of tubing can vary according to the producer, but usually consist of a water pipe to the first filter unit box (pre-filter), a second tubing to the sink pipe from the last canister filter (the RO body box) and another tubing to the filter box. In around five-stage systems, a “polishing” filter is also added to the storage tank water to the sink-top spigot.

The design of the tubing can therefore differ greatly, hence the directions on the correct tube connections are always verified by the producer.

Use the extra tube longitudinal for your use when attaching the tubing to the back of the cabinets or to allow cleanest installation wherever desired. Leave additional tubing if necessary should the machine be relocated at a later date. The tubing can also be cut to size if you choose for a smoother, incomprehensible appearance.

The yellow tubes run on the storage tank and the blacken tube is inserted into the RO mount, and suits the black tube into the drain adapter for this particular reverse osmosis device.

8. Place the drain

A drain tee is used in a whirlpool reverse osmosis system. Place the tea filter fit into the current drain pipe, mark the pipe and cut it with a hacksaw. Make sure the tee fits tightly before making the cuts.

Connect the drain tap fitting on the drain tube using the slip washers and nozzles provided — connections are made just as a drain tap is mounted.

Push the black drain tube of the filter into the tee adapter.

9. Conduct a pressure test

Switch on the water source and open the cold water to get some additional air from the pipes. Wait for two hours to start the pressure test. Once the tank is empty, the water would be a sluggish trickle. Enable it to run for 24 hours, and during this time, search for leaks.


Reviews are important

Check local plumber feedback on the internet if you have not already a person that you know and trust.

Look Around

  • Keep phone calls and ask questions after having found some respectable plumbers in your town.
  • Say you’ve already ordered a RO system and just want to install it.
  • Ask if the installations of RO are familiar to them.
  • Check if your hourly installation charge will be charged to you.
  • Ask how long it takes to install the standard RO system.
  • Request references.

Size Matters

We suggest a 50-GPD-rated RO system if you’re wondering what residential RO system is right for your household. The higher GPD system costs not much more than a lower production-rated system but offers improved production when the temperature of the water cool in winter months and when the membrane reaches and slows down to the end of life (typically at 24 months). Note that we sell full replacement kits to remove filter replacements from the deviation game.
