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 or 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.

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.

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 in a long time will cause a mineral imbalance in the body.

Is Reverse Osmosis Water good for Plants?
