RO Installation


Next time when you buy bottled water from any shop, think twice. A research says that bottled water or tap water could actually be a major health risk. If left for a long time, bottled water becomes contaminated with chemicals called phthalates that gradually seep into the water causing severe impact to the human hormone and testosterone when drunk.

The study further suggests that it takes an average 10 weeks for phthalates to get dissolved in water. Having said that, you can pretty much imagine how long bottled water is kept in stores before being displayed on racks and then you buy the bottle for drinking purpose.

As alarming as it may sound, researches reveal the associated risks with phthalates that include altered reproductive development, attention-deficit hyperactivity disorder, autism spectrum disorders, asthma, low IQ, obesity, spectrum disorders, behavioural changes, breast cancer, neuro development problems and type II diabetes.

Shopkeepers should, therefore, be alert when selling stocked up bottled water. To prevent causing harm to adults and children alike, it is advised to install an RO system to purify tap water before it reaches customers.


What is an RO system?

Popularly known as reverse osmosis system, RO uses a refined technology to protect you from any detrimental chemicals as present in your drinking water and eradicate waste water before it reaches the Hot Water System.

Let’s get into the details of an RO system and its installation process:


Different parts of an RO system:

  • Angle Stop Valve
  • RO Module
  • Automatic Shut-Off Valve vMembrane
  • Pre-Filter #1
  • Pre- Filter #2 (pre-filter #3 may or may not be applicable)
  • Bladder Tank
  • Post-Filter
  • Drinking Water Faucet
  • Drain Clamp
  • Tubing
  • Wastewater Saddle Valve
  • Quick-Connect Fittings

Installation site of an RO system

An RO system may be installed under a sink or in a basement. Avoid installing the RO system in a place exposed to freezing temperatures. You may successfully link it to an icemaker, refrigerator or other remote location using below 12” of tuning or by installing a delivery pump with it.


Installation of RO System: Steps involved

The plumbing and installation procedures of the RO system should adhere to local or state plumbing codes. Usually, an authorized plumber is required for the installation procedure, as directed by many municipalities. The various plumbing codes and installation procedures for RO unit installation:


Installing faucet

Plumbing Codes: The faucet should be fitted closer to the sink so that it empties into the sink and the spouts spin freely with maximum ease. Placing the faucet near the sink should ensure easy availability of drinking/cooking water.

If a sprayer connection already exists, it should be removed for faucet installation. You may either use a pipe cap or a plug to seal the sprayer connection, or leave the sprayer attached underneath the sink.

Before installing the faucet, it is necessary to create a faucet-mounting hole. To do that, check underneath the sink to make sure that the drill will not interfere with other fittings under. For the same, a 2” flat surface with 1-1/4” is required.

If the sink already has a hole for holding the osmosis faucet, there is no drilling required. Your next step should be mounting the faucet.

Installation procedures: For enamel, stainless steel, enamel, metal, porcelain on metal, cast iron sinks, the installation procedures are the same with the exception of metal. Extra precautions should be taken while penetrating the porcelain through the metal base.

  • Mark a point for ¼’’ pilot hole.
  • Drill through the porcelain by applying light pressure and slow speed. Stop when the metal is visible.
  • Cut the metal below the porcelain surface to make way for placing the faucet.
  • Continue drilling the pilot hole, until it becomes the size of ½”.
  • Finish and blend the sharp edges.

Points to remember: Air gap faucets are different from any normal faucet, and they need ¼’’ hole in the sink, instead of ½’’. Tools like chassis punch or a Relton cutter should be used for making the ¼’’ hole. If a large hole of the same size already exists, there is no need for drilling.


Mounting faucet

Installation procedures: First, set apart the hardware from the threaded shank. It should be known that Chrome base plates and rubber washers go up the shank to the faucet body.

If you can feel the threaded shank through the sink hole, position the faucet. Hex nut over the threaded shank from beneath the sink, and side lock the washer with a wrench.

Points to remember: Get someone to hold the faucet from the top of the sink to prevent it from moving out of position. If you do not get anyone to hold it, tighten up the hex up to a point that is less than fully tight. You can tighten the faucet base from above the sink.


Tubing installation and Angle Stop valve

Plumbing codes: The assembling of the Angle Stop Valve needs to be placed near to the reverse osmosis unit as much as possible. Take proper guidance regarding any substitutes that can be used instead of the angle stop adapter in case one is unable to be fitted under the sink. You should adhere to the rules and regulation regarding the fittings of the Angle Stop Valve that helps to supply feed water to the RO unit.

Approach us at Perfect Healthcare as we offer convenient simple and easy connection between the base of the riser tube and the angle stop that is placed between the cold water shut-off and the faucet. Remember, the Angle Stop Valve serves as the water feed connection to the RO system.

Installation procedures: This is how you install:

  • First, close the cold water supply by using the Angle Stop Valve positioned beneath the sink.
  • Shut off the Angle Stop Valve and then open the handle on the faucet towards the cold water side. This will help to free pressure on the side.
  • With the help of an adjustable wrench disconnect the riser tube from the cold water shut off.
  • Separate the tubing from the valve for making room for the company’s Angle Stop Valve.
  • Plumbers should make sure that they manually tighten swivel of the Angle Stop Valve with the cold water shut-off threads.
  • The next step is to attach the riser tube with the end of the Angle Stop Valve with a wrench.
  • Once the above are done, connect a 1/4’’ tubing between the inlet of the RO unit and the company’s Fitting on Angle Stop Valve.

If the riser tube is made out of copper:

In that case, it would require giving a flex to the copper for creating 2” of space for the Angle Stop Valve. On the other hand, if the copper tube measures 3/8’’, the flexing can be done with hands.

It should be noted that the company’s Angle Stop Valve functions with riser tubes and 3/8’’ shut-off valve. When in cases of traditional plumbing, bigger size riser tube along with shut-off valves is operated, and therefore it becomes inevitable to replace the shut off valves and the old riser tube with 3/8’’ parts.

Otherwise, an alternative connection is used for pulling water up to the RO system. Aside from all the options that have been mentioned, piercing valve, self T fittings, faucet adaptors are also used to establish connection between the faucet and the top of the riser.

If the riser tube is made out of flexible material:

In today’s industrial scenario, most riser tubes are made out of flexible materials like braided stainless steel or 3/8’’ gray plastic tubing or braided plastic. The biggest advantage of using flexible tubes is they can fill in space for the Faucet adaptor by flexing it. Puriefiersindia.co.in Angle Stop Valve used with flexible tubes ensures that there is no additional shorter riser tube required.


Installing Drain Saddle Valve

Before getting into the details of the installation of Drain Saddle Valve, let’s understand the functions of the same. A Drain Saddle is used in an RO system to create a wastewater connection with the drain located below the sink. Note this that the drain beneath the sink is created to fit around any standard 1-1/2’’ OD drainpipe.

Plumbing Codes: Make sure that the Drain Saddle Valve is fitted above the P-trap or on a vertical or horizontal drain. Drain Saddle installation should be avoided near any garbage in order to avoid the clogging of the drain line with debris.

Installation Procedures:

  • Position the Drain Saddle Valve at the mark created for the opening, which means the chosen location.
  • Make a drill of ¼’’ from only one side of the drain pipe
  • Avoid any baking from the gasket. Then, use the adhesive side against the fitting of the half of drain clamp around the hole.
  • Place both halves of the drain saddle on the drain pipe to ensure that opening of the saddles are positioned along with the drill hole. You can make a small drill to make sure that the drain clamp is precisely placed.
  • Use nuts and bolts to tighten the drain saddle clamp securely on the nuts. Having said that, make sure that you do not over-tighten the drain saddle clamp. Also, make sure that enough space is left between the saddle halves on each side.

Installing RO components

The initial step is to install O-ring RO membrane, sediment pre-filter and carbon pre-filters in vertical mounting housings.

Points to remember: Try and push the RO membrane into Membrane housing as far as possible. Take care of using gloves when handling the filters and membranes.


Initial Tubing connections

As far as under sink installations are concerned, you should first take care of the under sink tubing connections at the given time.


RO unit installation

Plumbing Codes: The reverse osmosis unit should be installed keeping in mind the location of the supply tank. Ideally, the RO unit should be installed with the tank at the back and the cabinet in the front. It is recommended to install the RO unit either to the right or left side of the cabinet beneath the sink. This will allow for easy access to the unit for maintenance and repairing purpose in the future.

Installation Procedures: Lift the RO unit of above 2’’ above the surface, and mark the exact location of the mounting holes as required. Now, to fix the mounting bracket slots, use mounting screws through the drill holes and fix them. This is to ensure that the RO unit swiftly glides on the mounting bracket slots.

Point to Remember: If the cabinet sidewalls are not strong, the RO unit may be left on the floor with screws by putting it against the cabinet in the vertical direction.


Placement and Pre-Fill of the Supply Tank

Plumbing Codes: The storage tank should be pre-filled with water to ensure adequate pressure in order to flush out carbon post filter and examine any leaks as well.

Installation Procedures:

  • Make sure that the bladder tank is positioned within a distance of 10 feet of the faucet. Once done, ensure that the feed line is connected properly to allow the RO unit run straight away to the bladder tank.
  • A 3/8’’ x ¼’’ reducer is used for the same.
  • Keep the water line open for filling the bladder until it stops.
  • Once the bladder is full, stop the tank valve and the feed pressure, open the tube from the reducer and disconnect the reducer from the tank valve.
  • Make sure that the supply tank is positioned just below the counter or within 10 feet of the RP unit.

Points to Remember: Know this that the tanks should be pressurized with air at 7 psi prior to the installation.


Last stage of tubing connections

This is the last stage of tubing connection, so before you go with it make sure that all the RO components are in the exact position.

Installation Procedures:

  • Start by cutting off any extra length of the tubing. Use appropriate cutting tools and square cuts for performing the same.
  • Check for any crimps left in the tubing. Even the slightest residue of crimp left should be cleaned.
  • Maintain a very short length of tubing between the tank and the reverse osmosis unit to ensure excellent flow of water.
  • The purpose of tubing is to follow the contour of the cabinets.

Points to Remember: The Drain line (measuring ¼’’), which comes with a 3’’ cylindrical drain flow restrictor in it, is attached to the membrane housing. The reverse osmosis unit is connected at this point. Taking away the drain flow restrictor would mean failure in the RO system.

Now that you are aware of the installation procedures of an RO system, the next step is to learn how to connect an RO system with home appliances.


For instance, how to connect an RO system to a refrigerator, water dispenser or an Icemaker? Steps for Installation:

Hire a water treatment expert to connect your reverse osmosis system with your water dispenser or fridge. The RO should be installed beneath the kitchen sink, but only an expert can guide you with the small and important details.

It should be known that the water pressure in RO should be at 2/3 of the pressure as of the cold water line. Another point to remember is that some refrigerators may require hiring a local water treatment specialist for checking respective pressure considerations for installing the RO.

Here are the instructions for connecting an RO system with fridge or dispenser:

  • After stopping the cold water line connected to your RO system, locate the tube that links the RO system with the water faucet.
  • The next step involves cutting the tube (about 10 inches), to allow water drain from the point into a bucket which should be placed under the tube at that position.
  • Now you install the Tee, which is done by fitting the tubing that is linked to the RO system. Make sure that the fitting is done tightly by forcing the two aligning ends of the tubing as distant as possible. Lastly, pull it safely to check if the tubing is secured safely.
  • Install the other side of the aligning Tee fitting into the left cut tube linked to the faucet.
  • Next, cut off a 10’’ piece from a new ¼’’ tubing.
  • Insert this 10’’ piece of tube through the Tee line, but at the same time make sure that it should be perpendicular to the tubing running from the RO system to the faucet.
  • The next step is to attach the remaining end of the long ¼’’ tubing to one end of the shut off valve. However, before that link the inline shutoff ball valve to the one side of the tubing. Keep the valve turned off until the holding tank is filled.
  • Now, link the ¼’’ polypropylene tubing from the reverse osmosis system to the refrigerator. It should be noted that 20 feet of tubing is sufficient, but you use up to 30 feet if the tubing runs that long.

    The question is what if you have more than 30 feet of tubing running through the RO system and the refrigerator? You may then use a tube longer than ¼’’ fittings for the best result.
  • If required, use a ¼’’ x ¼’’ union of tubing for connecting it to the ice maker or fridge.
  • Maintain the recommended water pressure to the ice maker/fridge, by complying with the refrigerator manufacturer properties.
  • Now the reverse osmosis system is ready to be installed with the RO system. At times, when you need to change the reverse osmosis filters, do close off the inline valve until the filter change is complete. Make sure that the system is thoroughly cleansed at the end.

Precautions to be taken regarding the Refrigerator and RO hook-up Safety

  1. Sometimes, more than 30 feet of tubing is required, without making any changes to tubing longer than ¼’’ and adaptors. In that case, there is no need for connection of a reverse osmosis system to a ice maker or refrigerator.
  2. The point to be noted is that any advanced RO system generally works between a pressure ranges from 40 to 85 psi. Any pressure lesser than that will eventually affect the quantity and quality of water that will get deteriorated.
  3. Seek expert help to get the membrane checked annually and the filters changed on a routine basis at least once or twice a year.
  4. Check if the water pressure is optimal in the tank, so it is instructed to install the pumped RO system that is needed. If the water pressure is very high, then it can cause severe damage to the RO system. Install a pressure controller if the water pressure is higher than 85 psi, which will decrease the water pressure.
  5. Does your refrigerator have a copper piping for the water dispenser or icemaker line? If, yes, do not connect the RO system with the fridge, since copper fittings may possibly cause corrosion.

After the aforementioned instructions and installation suggestions, we would like to state that our laboratory-tested RO systems guarantee the right functioning. Periodic maintenance is required to ensure that your RO system stays in the best of performance and offers stress-free services. These are what we suggest regarding RO system maintenance:

  • RO membrane- maintenance in every 24 months
  • Pre-filters (sediment)- maintenance for at least once annually
  • Pre-filters (carbon blocks)- maintenance for at least once annually
  • Post filter (carbon)- maintenance for at least once annually

The above installation procedures, maintenance and care instructions from us ensure the best health for you and your family with a properly functioning RO system at your home.
