Learn Carefully – How to Install the Water Filter?

The most important thing for you to know is that using inline filters can:

  • Cut down the cost of filtered plastic bottles that you buy

  • Keeps the environment safe

  • Makes water soft and free from all kinds of dirt

  • Saves space

What’s next?

An inline water filter needs to be directly installed in the line of flowing water so that the water should pass through it and becomes suitable to drink. 

Its main function is to remove all the harmful substances, elements, metals, and sediment or dirt from the water.

Most probably it is the most useful filtration tool that consists of high-tech features that prevent limestone formation and fungus growth.

Tip: Before the installation, make sure you have read the instruction manual that will help you in the installation of the filter. 

Step 1: Identify the normal supply line of water that your home is receiving or is delivering cold water to your house.

Step 2: Take the wide connecting hose that should be flexible and adjustable to any supply line that you want.

Step 3: Loosen the nuts of the hose that are attached, and twist it. Filters like these can easily connect to ¼’’ of the water supply line. Depending on the compression, fittings leads to quick installation. 

Step 4: It's good to attach the cartridge to the filter system. Also, if you are using the water filter for the refrigerator, then make sure you have a proper inlet and an outlet housing device in which a tube can be inserted.

Step 5: To protect the water hose from kinking, the water hose protector is required to prevent it. 

Step 6: Directly insert the filter in the main water supply line or the appliance. So that when the water passes through it, it should be pure and clean until it reaches the appliance or a tap. 

It is as simple as one, two, three!

Instruction: After installing the filter, first turn-on the water supply again. Secondly, check for any water dripping or side leakage. Thirdly, test the connection of the hose or tubing. Finally, you are all set to drink clean water and use filtered water for domestic or other purposes. 

Tidbits: It makes tap water as clean as freshwater without the reverse osmosis filtration that sucks all the minerals that your body requires. 

Installation – Where to Install it, Particularly?

It can be installed on any hot or cold water-using appliances. Besides, it can also reduce scale formation and prevent corrosion. Besides, the selection of the location is a primary factor that you should consider before you install it. 

The list of the appliances is as below:

  • Dishwashing machine

  • Washing machine

  • Pipes, faucets, showers

  • Water heaters or greasers

  • Boilers 

  • Trailers,  boats, RVs

  • Refrigerator and ice makers

  • Sink, water fountains

  • Beverage equipment

  • Pressure washer

  • Garden or any water supply pipelines

Trick:  Hot water deposits different scales, elements, and harmful chemicals on the appliances.

Therefore, to eliminate or prevent the deposits these filters contain polyphosphates. This develops a layer of protection on the metal surface to keep it secure. 

Effectiveness – Want to Find Out?

Filters like these have porosity media and have embedded activated carbon to ensure effective filtration. 

However, this filtration technology is efficient due to the variable micron level and performance. Therefore, it varies from filter to filter and company to company. 

Some of the filters show a 5-micron rating while some show 20. Though the larger the micron number is, the larger will be its capacity to filter out large particles, conversely, the smaller the micron number, the lower will be its ability to filter out large particles. Thus, it can remove smaller particles effectively. 

Furthermore, it offers multi-stage filtration while using the advanced and latest KDF and GAC to ensure high-efficiency filtration.

It also contains the ability to remove fluoride from the water. KDF and GAC are considered the best treatment solution to remove harmful chemicals from the water that are responsible for causing unpleasant tastes and odor. 

These carbon filters are durable, easy to use, and ensure a higher water flow rate. 

Life Span – Warranty That You Need!

These warranties of the filter also differ from one item to another. Some of these have a 6-months life expectancy while some last for a lifetime. So, it varies from 6-months to 5-years. 

But, if you want to maximize the system efficiency and performance, then it is a must that you should change the filter frequently along with the cartridge. 

On the other hand, if you notice that water flow has become slow and your water tastes bad, so immediately replace the filter.

Tip: Some of these filters should not be used with the already disinfected water or well water. 

Capacity – That Ensures Consistent Flow!

Usually, the capacity of every water filter is different. Still, if you are interested in finding the capacity range, then it might vary from 1500 gallons to 20,000 gallons. 

While some of them even possess 10,000 gallons of water flow. So, drinking and using disinfected water should be your ultimate goal to live a healthier life. 

Cost – Is it Affordable?

If you are unaware of its price and affordability factor, then it's good for you to know that it is economical. 

Moreover, it depends on the efficiency, performance, capacity, and maintenance of the filter whether you need to replace it frequently or not.

So, if you are handling it with care, then it might help you to cut down your purchase. 

How it Follows the Flow? – All About Inline Filter’s Filtration System

There is a fact that different filters will follow different filtration mechanisms, but the general principle for filtering the inline water remains the same. How? Let’s see:

In the beginning, water enters the filter.  Then it reaches the sediment filter. Here the filtration system will remove all the large particles like debris, silt, sediment, and sand. 

Secondly, water go-through the activated carbon filter. All the contaminants and harmful elements are removed here.

Next, the water reaches the mineral and copper-zinc filter.  Here, it will remove all the left-out elements like heavy metal and chlorine.

Not every filter needs to have a descaler or a water-softener because some of the filters do not include this feature. 

However, if some of them possess it, then its function is to soften the water and make it salty. 

Easy to Repair – Trouble-free Replacement

Till now you might have already known that it is easy to replace. Though it might take 10-15 minutes to get done with it. 

All you have to do is follow the water flow sign and direction of the installation of the filter and that’s it.

To fix the hard water you need to use the filter that has a water softener filter. It will help you with converting your hard water into soft. But before this, it is better to understand the installation procedure and analyze the cost of the filter.

How do I find the water flow rate in my home?

You can easily find the water flow rate once you open the faucet or a nearby pressure tank. Make sure the water is running and turn on the well pump.
Then turn off the tap and count the time for how much the pump is running. Count the gallons of water and pump flow.
Finally, the number of gallons you have filled will give you a final flow rate. But do get it checked by an expert as well.

Can I install the entire inline water filter equipment myself without any help?

Yes, you can install the entire equipment by yourself wherever you want to. But, first, decide the type of filter you want to use and then follow the DIY available and learn how to install it.
All you need is an installation kit, screwdriver, nuts and bolts, drill machine, and other related tools.

Does the water filter help to remove bacteria?

Reverse osmosis helps to remove the bacteria, while inline filters do not effectively make you get rid of them. However, the easiest way to remove the bacteria from the water is to disinfect it through ultraviolet radiation and by chlorination as well.

Can the tap filter help me to improve the taste of the water?

Yes, it will help you to improve the taste and odor of the water. It is responsible for removing particulates and pathogens that make water suitable for drinking.
