6 Steps On How To Install A Water Filter

9 September

Have you been drinking out of the tap all this time? If yes, think again, as it might not be as safe as previously assumed.

In Australia, it’s relatively safe to drink tap water compared to other parts of the world. However, the water from your tap can still be contaminated with metals, chemicals, or organic and inorganic compounds.

To be safe, installing a water filtration system in your kitchen is recommended to access chemical-free drinking water or clean water. A whole house water filter is also a great alternative to bottled water, increasing plastic pollution and contributing to global environmental impact.

So, if you’re considering whether to call a plumber to install a house water filter, don’t worry; you can install it yourself without much trouble. Depending on your chosen system or filter type, you can have fresh filtered water, pure water, alkaline water or purified water tasting better than bottled or unfiltered water. We’ve created this guide to let you know how to install an under-sink water filter to make the process easier, and soon you can enjoy your new filter and drink filtered water.

6 Steps On How To Install A Water Filter

Step 1: Mount The Dispenser

The first step for installing most under-sink water filter systems would be to mount its dispenser on your kitchen sink or counter. You’ll need to ensure a free hole beside the faucet.

If not, follow the manufacturer’s instructions for the water filter to drill an appropriately sized hole in the sink. However, it’s best to drill a hole in the countertop for those with a traditional-style porcelain sink.

You’ll require a titanium graduated step bit to make the hole in a stainless steel sink. While having a diamond-ground drill bit makes the job easier when working on a marble or granite surface.

Step 2: Install A Saddle Valve

Next, move below the sink, find the water supply lines, and install a saddle valve to draw the purifier’s water. Be careful, as you need to place it in the cold water supply line rather than the hot one, usually red-coded.

Before installing the saddle valve, turn off the water supply valve and empty the line by turning on the faucet. Then, drill a hole in the intended water supply line, and follow the manufacturer’s instructions to install the valve.

Begin by cleaning the water pipe to ensure that the surface is smooth for the self-puncturing lance to pierce without fail. Retract the lance using the valve’s handle and place the brackets or gaskets over the pipe.

Ensure that the brackets are in place securely before piercing the water supply line by moving the handle of the saddle valve clockwise until it stops. You should be able to feel the lance go through the pipe.

And remember to clear the under-sink space of all unnecessary stuff beforehand so nothing can get in your way.

Step 3: Place The Cartridge Filtration Unit

The water filter you choose will come with two or more cartridges depending on its filtration style. So, ensure enough space under your sink to fit everything.

It should ideally be positioned between the cold water supply line and the dispenser so there are no kinks in the tubing. Many people prefer to place the cartridges on the cabinet door if there isn’t enough space on the wall.

But ensure it’s easily reachable as you’ll need to replace the cartridge filters after a certain duration as specified by the manufacturer.

Step 4: Hook Up The Device 

Cut an appropriate length of tubing to connect the saddle valve with the filtration system but remember that it shouldn’t be too short, or it may develop kinks. The tube should be long enough to have space for a compression fitting if required.

Press the compression fitting onto the tube and hook it up with the saddle valve. Also, you will need an adjustable wrench to get a tight fit and prevent leakage.

Step 5: Connect The Filtration Unit And The Water Supply Line 

After connecting one end of the tube to the saddle valve, it’s time to attach the other end to the main filtration unit. Similar to the earlier step, you will need to add a compression fitting and then thread it onto the inlet port of the water filtration unit. So, tighten the nut using your hand, and if required, make another turn or more with the wrench.

Step 6: Finish By Connecting The Water Dispenser 

The final step is to cut another tube between the water filtration unit and the dispenser. Install compression fittings on both ends of the tube, and connect them to the ports before turning on the water shut-off valve and the dispenser.

It’s recommended to flush out at least 10 litres of water after installing a filter, so let the dispenser run for approximately 5 minutes. Once the carbon particles are out of the system, the water from the dispenser should be clear and have no distinct taste.
