How to Install Reverse Osmosis System?
A reverse osmosis system is one of the efficient systems that requires not much effort to install. The whole system is simple enough to be self-install by anyone at home. You will just need to follow these steps.
Location
Before installing anything, you will need to decide where you want to install the system. Most of the systems can fit neatly into any kitchen cabinet and under-sink cabinet.
Connect to the cold water line
There are a few options to connect the cold water line to the reverse osmosis system. There is a standard method called the saddle valve.
The package often comes with a saddle valve. You will need to assemble saddle valve clamp on the cold water line. Adjust the valve by tightening the belt so it is tight enough to fit the contour of the pipe.
Drain line connection
About 6 inches above the trap, drill a 5/16″ diameter hole through one wall of the pipe. Now, you can take out the drain clamp and start attaching the drain clamp to the pipe. Remember to make sure that the hole in the clamp is aligned nicely with the hole in the pipe. Then tighten the clamp. You are done with this step.
Faucet space preparation
For installation on porcelain, enamel, ceramic, metal, or cast iron, you can start with marking the center of the counter a ¼” pilot hole. Then carefully drill a hole with masonry pit through the porcelain level. You just keep going until the metal shows. Remember to use light pressure and slow speed to not go overboard. When you reach the metal section, switch to a standard metal cutting and continue to cut through the metal. Keep enlarging the pilot hole until the hole reaches ½ inch diameter.
Faucet mounting
Now, take the faucet out of the package. Disassemble hardware from the trodden shank. Then, you need to feed threaded shank through the sinkhole. Adjust and orient the faucet to make sure your faucet facing the correct way.
From below sink, slide lock washer and hex nut through the threaded shank. Then, use a wrench to tighten the faucet carefully.
Color-coded system hook up
Most of the reverse osmosis system comes with color-coded tubes to help you install the system better.
Connect the saddle valve to the units orange feed water line. Normally, there will be a plastic Delrin sleeve included in the installation kit. Use the plastic Delrin sleeve to help you with this step.
Connect the black line directly to the drain clamp assembly you have set up earlier.
Connect the green line to the reverse osmosis water storage tank
Connect the blue line to the faucet from the system.
Start the system
Remember to turn on the system step by step. First, turn off the storage tank ball valve so no water can enter the tank.
Then open the reverse osmosis faucet on the sink. The initial water dripping out from the faucet can be black or very cloudy in color, this is the water system flushing the carbon fines from the carbon filtering system. Let it keep dripping for 10 to 15 minutes before closing the faucet.
Finally, open the valve of the reverse osmosis storage tank. Leave it open to allow the tank to fill. Once the tank is full, turn on the faucet and drain the whole system completely. Then do this process again. Shut the reverse osmosis faucet off and allow the system to refill.

+ Does reverse osmosis remove fluoride?
+ Does reverse osmosis remove chlorine?
+ Does reverse osmosis remove lead?
+ Does reverse osmosis remove bacteria?
+ Does reverse osmosis remove nitrates?
+ Does reverse osmosis remove salt?
+ Does reverse osmosis remove calcium?
Of course. Answer is Yes
How Pure is Reverse Osmosis Water?
Reverse osmosis system uses a semipermeable membrane to remove ions, molecules, large particles, dangerous compounds, and chemicals from drinking water.
There are typically two types of membranes: CTA (Cellulose Triacetate) and TFC (thin film composite).
The CTA membranes are made to allow contact between chlorine in the water and the membrane. This type of membrane needs a small amount of chlorine from the water to prevent bacteria from forming a layer on it. Reverse osmosis system that uses this membrane often has a rejection rate for impurities at 85 to 95%.
The TFC membranes are made of synthetic material and do not require any chlorine to work. On the other hand, the TFC membrane needs most of the chlorine to be removed before the water runs through. This type of membrane has a rejection rate for impurities of 95 to 98%.
In general, reverse osmosis water is at least 85% pure, making it one of the purest form of water for daily consumption.
How to Maintain a Reverse Osmosis Water System?
Many reverse osmosis may last 10 to 15 years depending on how well you take care of your system. The most important thing you need to pay attention to is changing the filter.
You should set up a schedule to regularly change the filters. Read your manual carefully to know how many stages are there in your system. Depending on the number of stages, you can know how many filters and what filters you can use for what stage.
Much reverse osmosis systems use carbon filters. Carbon filters should be generally replaced once every 12 months to make sure the filters always stay in top-notch condition.
There is nothing as important as the filters in your system. They take care of the most important jobs within the reverse osmosis system. Take care of your filters carefully so you can make the whole system not only last longer but also provide more efficient and quality water.
Is Reverse Osmosis Water Bad for You?
As mentioned before, reverse osmosis water is very beneficial for your health. However, reverse osmosis water also has its fair share of disadvantages.
The water becomes ‘too pure’. The reverse osmosis system removes up to 99% of all particles including good bacteria and mineral particles. Together with many dangerous and harmful particles, many good and necessary-for-health particles. Your water will become tasteless and will do nothing for your health neither improving nor degrading your health.
Most of the water coming out of the reverse osmosis system is acidic. When all the minerals are removed from the water, the water will be left acidic. Acidic water is not good for maintaining a healthy pH balance in your blood since your blood needs to be slightly alkaline. Some medical research also proved that drinking acidic water for a long time will cause a mineral imbalance in the body.
Is Reverse Osmosis Water Good for Plants?
There are both benefits and disadvantages of using reverse osmosis water for plants.
For growers who need to control the level of nutrients and minerals feeding to their plants, using pure water will give no effect for your plants, neither good nor bad. There are no impurities or any form of minerals in the water, so you can use as much reverse osmosis water as you want with no worries that the balance of minerals and nutrients of your plants is disturbed.
The problem with reverse osmosis water is the waste of water while going through the process. With one gallon of water, after going through the filtration system, there will be a maximum of about ½ of the gallon of water left. Normally, the water wastage is about a 1:3 ratio for average reverse osmosis water. If you have a large garden, be prepared for a big water bill.
Conclusion
Nothing is perfect. So is reverse osmosis water. However, the benefits of reverse osmosis water are worth more than the disadvantages. Having clean and healthy water is very important. And nowadays, when it is easy to buy yourself and set up a reverse osmosis system at your home, there should be nothing stopping you from drinking healthy reverse osmosis water. What are you still waiting for? If you worry about your tap water at home, get yourself the best reverse osmosis system.
I have a water softener installed yet after hand washing and machine washing my glassware has streaks and spots. I also have a RO system and after hand washing my glassware and rinsing it with the RO water I still have streaks and spots although less than just using the softened water. The company who installed both my softener and RO system came out checked my water and told me that was the best they could do for me. Do you have any recommendations that could alleviate my problem?
Can a regular mixing valve bar faucet be used with an under sink reverser osmosis system? Or do you have to use the typical filter water faucet? If so, why would the RO system not push water through the faucet?
Very helpful, thank you. We use Waterdrop for years, and very cost-effective with good value. Use advanced activated carbon for high-efficiency filtration and maximum removal of impurities. It also makes my coffee tested better:)
