Using Reverse Osmosis Water Filter System

How To Install Reverse Osmosis Water Filter System?

Reverse osmosis water filter system is a process which facilitates the removal of salt from water making it fit for human consumption. This system is very popular and mostly used is recycling and treatment of waste water. This process allows larger quantities of water to pass through the system more efficiently. Actually this is when the solvent of the low concentrated solute solution that moves through the membrane to get into a higher concentrated solution hence weakening it. It starts with saltwater solution placed on one side of the tank and fresh pure water on other side of the tank separated by the semi-permeable membrane. Below are key steps on how to install reverse osmosis water filter system.

How to install reverse osmosis water filter system :

Ensure that you complete all plumbing processes in accordance with the state or local authorities.

Faucet installation

Disconnect the sprayer for faucet installation. Using the pipe cap, seal the sprayer connection and drill to make faucet mounting hole. As you drill, check below to ensure that you don’t interfere with other things below. Create a two inch flat surface and position the faucet that it empties to the sink. Installation procedures for enamel, porcelain, ceramic on the metal iron are

  • Mark the center with a center punch to create ¼ inch pilot hole
  • Using a masonry pit, drill the pilot hole through the porcelain up to the point when the metal will show up
  • Switch the bit into the standard metal cutting and continue cutting through the metal that is located below porcelain surface
  • Enlarge the pilot hole up to � inch

Mounting the faucet

Disassemble hardware from a treaded shank and chrome the base plates and slide rubber washers up the shank into a faucet body. Feed the threaded shank through sink hole and then orient the faucet. Slide the lock washer from below the sink and then hex the nut over the threaded shank. Tighten with the wrench.

The angle stop valve and the tubing installation

This valve provides simple and easy connection between angle stop and bottom of riser tube. This valve has a built-in shut-off function that provides a feed supply connection for a reverse osmosis system.

  • Shut off the supply of cold water with the angle stop shut off function which is located below the sink
  • Relieve the pressure through opening the handle on the faucet
  • Disconnect riser tube using adjustable wrench
  • Make room for angle stop valve by moving the tubing away from valves
  • Connect swivel to the threads on a cold water shut-off
  • Connect riser tube to male end of angle stop valve and then tighten it using the wrench

Drain saddle valve installation

  • Position drain saddle valve in a selected location and then mark the openings
  • Drill ¼ inch hole at the mark
  • Remove the backing from a gasket and then place the adhesive into the fitting half of the drain clamp
  • Secure the drain saddle clamp on the valve using the bolts and nuts
  • Complete all initial tubing connection

Install the RO membrane in the vertical mounted housings and then mount the RO unit to the left or right side of the sink. You can then pre-fill and supply the tank placement and do the final tubing.

How to install reverse osmosis water filter system may seem to be a challenging procedure but if you follow the above steps, the process will be very simple. It only starts by installing the faucet, mounting the faucet, installation of the angle stop valve and tubes, and installation of the drain saddle valve. You will also do some initial tubing connections and the RO component installation. They are all simple procedures and within a short period of time, your system will be fully installed.

How reverse osmosis water filters work?

Reverse osmosis water filter is a filtration process that improves the taste, odor and even appearance of drinking water by simply removing any contaminants which cause a taste and odor problems. This system provides better and quality water at the lowest cost ever. The system have few moving and replaceable parts that makes the system easy to clean and maintain. It helps remove impurities and pollutants from water such as nitrates, fluoride, pesticides, bacteria, arsenic, pharmaceuticals and many more. This filtration system is a perfect solution if you want clean and tasty water. This is a simple straightforward filtration process where dissolved inorganic solids are removed from the solution such as water. The following are simple steps on how reverse osmosis water filters work.

Step 0ne: Pre-filtration

The first step in reverse osmosis water filtration process is the pre-filtration. This step is meant to protect and ensure the membrane is in the correct state. Pre-filtration removes all large sediment such as dissolved solids and it also reduce chlorine. It is also referred to as the carbon block filter or sediment filter. It helps in conserving the membrane that may get clogged easily due to excess sediment. This process works well when you start with water and make it great. At this stage, ensure that you don’t use hard water in the process unless it is below 10 grains in every gallon. If water is too hard, you can start with water treatment solutions. Remember to install the water softener before you install the system.

Step two: The reverse osmosis membrane

At this stage, water is forced through semi-permeable membrane under pressure. This membrane is actually a synthetic plastic material which enables the passage of water molecules. However molecules such as chlorine, sodium and calcium and other large molecules such as urea, viruses, glucose and bacteria cannot pass. Water right uses a thin film composite membrane in the eclipse systems. This kind of membrane is actually resistant to breakdown of bacteria and has got high rate of rejection. The TFC membranes are not good at chlorine-resistant and this is the reason why carbon pre-filter is mostly used.

Step three: Post filtration and final polish

Before your water is ready for drinking, it must go through the second carbon filter which ensures there is a perfect removal of any contaminants that remains in the membrane. The water will then fill up the storage tank waiting to be used. In-line activated carbon filter gives water one last polish. It is normally used in removing odors or flavors which may come from system’s holding tank. After all this processes, your water will be ready for drinking.


How reverse osmosis water filters work is very simple. This is a three step process which is easy and simple to understand. Reverse osmosis water filters ensures that you have clean and soft water for drinking. It helps in removing sodium together with other contaminants to produce clean and tasty water. The reverse osmosis water filters are normally installed under the kitchen basement or sinks. Installing it is simple and water from this system can be used in different ways.
