Where do you plan to place the water filtration system?

There are different water filtration systems you can use at home. Here you need to consider if you want to mount it under the sink, inside a cabinet, on top of the counter, or do you need a whole-house model. No matter which one you select, always look at the size available.

By doing this, you can determine if the reverse osmosis system will work where you plan to use it.

How does the water taste?

Whether you use well or city water thinks about how the water tastes. Does the rain have a terrible tang to it? If it does, you need an RO system with an added filtration stage to help remove smells and lousy taste. Furthermore, you need to do a pH test using a pH tester. By purchasing extra water, the filtration stage helps to stabilize and balance the pH level making it healthier to drink.

How essential are the extra accessories?

Sometimes you will buy an RO system to install in the sink cabinet and use the supplied faucet. If added extras are essential always, check the quality of the parts included from the tap to filters.

By following these simple steps, you can determine which water filter will work best in your home.

How does a home RO System Work?

You connect the reverse osmosis system to the cold water line. When turning the tap open, the water goes through the filtration system by passing through various stages.

The water is stored in the reservoir for use, and whenever you open the faucet, the processed water comes out. To find the correct one to use in your home, you can look at the provided models reviewed here. You can even find them available at different online and local hardware stores.

How clean is the reverse osmosis system water?

Depending on the brand you buy, you can expect the RO system to remove up to hundreds of impurities found in water. The filtration system removes organic to hard particles and chemicals from water. You can expect the filtration system to remove:

  • Chlorine
  • Fluoride
  • Lead
  • Bacteria
  • Salt
  • Nitrate
  • Calcium and more

Furthermore, the unit works with a semi-permeable membrane that also removes large particles. You can find two types of membranes a-Cellulose Triacetate (CTA) and Thin Film Composite (TFC.) The CTA filter allows allowing for contact between the chlorine in the water and the layer.

With the small amount of chlorine, it helps prevent bacteria from forming. The system that works with such a film eliminates up to 95% of impurities. TFC filters have a plastic construction, needs no chlorine, and remove most of it before the water runs through the system.

What are the Benefits of Using an RO System?

Using a reverse osmosis system at home has many benefits, as discussed here!

Removes sodium from water:

Sodium is not dangerous and usually not filtered out in other filtration systems. However, if there is a high level of the chemical present, it makes the water taste bad. With the RO system, it eliminates the sodium to improve the water for drinking, cooking and provides you with clear ice cubes to enjoy with a sundowner. You get water that smells and taste better at the same time.

Improved health benefits:

When you drink contaminated water, it can affect your health as contaminants can make you sick. You may not feel the effects at first, but with time, it can lead to different ailments taking place in the body.

How Do You Install The RO System?

Installing the reverse osmosis system does not take much effort. The product comes as a complete kit and depends on the model you buy. The important thing is to do the following:

  1. First, decide where you plan to install the system as some can fit comfortably under the sink or in any cabinet.
  2. Further, you need to connect it to the cold water line, and the package typically includes a saddle valve to keep it securely attached. You need to adjust the tap by tightening it to fit the shape of the pipe.
  3. You need to drill a 5/16-inch hole about 6-inches above the trap through one wall of the pipe. Remove the drain clamp, attach it to the hose, and tighten it to prevent leaks.
  4. If you have bought one with a faucet, you need to make a hole in the counter about ¼-inches by using a masonry bit and keep enlarging the hole until it has a ½-inch diameter.
  5. Disassemble the hardware from the shank, thread the shaft through the hole, and adjust the tap to face the correct way.
  6. Place the lock washer and hex nut through from below the sink and tighten the faucet.

However, if you have a coded color system, here is some advice on how to hook it up with the tap:

Start with the orange feed water line and connect the saddle valve to it. You may find the kit comes with a Delrin sleeve. Make sure to use it as it makes this step easier. Take the black line and connect it to the drain clamp you have set up earlier. Now join the green tube to the RO water storage tank and attach the blue line to the faucet.

Once everything is set, you need to start the system gradually. Start by turning off the storage tank ball valve to prevent water from entering the tank. Open the tap and let the water drip for up to 15-minutes to allow the carbon fines to flush through and close the faucet.

Finally, you can open the valve of the storage tank and leave it open, allowing the reservoir to fill. Once the containers full, you can turn the tap, drain the system, and repeat the process. Now shut the faucet off and allow the unit to refill.

Maintaining the RO System

Your reverse osmosis system can last up to fifteen years if you take care of it. The crucial thing is to keep an eye on changing the filters. You can do this by setting up a schedule to check them regularly. Always read the manual to know the different stages available in the unit.

Depending on the water filter you have, the most common cartridge is the carbon one and needs replacing once a year. If you take care of the filtering system, it remains in tiptop condition to provide you with clean water to drink.

It will be possible that if you are not going to take the maintenance of the reverse osmosis system seriously then you will not be able to get the most out of it. There are so many people who ignore or forget about the maintenance of the RO system. So they will either have to change the cartridge every two or three months or they will have to drink unfiltered and lower-quality water.

Even though you think that the Reverse Osmosis System does not need any kind of maintenance, you should do it. So that the RO system will not lose the quality and taste of the water that you are drinking.
