Install the Under Sink Kit.

Install the Faucet.

Install the Water Filter.

In this article, we will walk you through the third and final stage of your installation.

Before You Start

The first step is to get everything out of your cupboard and make sure that it’s safe to start working there. Ensure there are no electrical components and you’re not going to get hurt or injured in any way. You’ll see we've taken the cupboard doors off today. That's so you can get a good view of what's going on, and it just makes it a lot easier for me to get in and do the installation.

Then you'll need to get in there and make sure you've got plenty of room to install the water filter and something to screw the water filter onto. You'll have a couple of screws that will go through the top of the housing bracket to hold the filter in place.

Turn Off The Water Supply

In the video, we turned off the water from underneath the sink. If you can't turn the water off there, you've got to go out the front or back of the home to the water meter and turn it off at the main water supply. Then you'll have no pressure pushing on the house.

Turn off the water supply. Come back inside, turn on the tap to empty the waterline. Expect a little bit of water to come out. There will be a bit of pressure. Release the pressure, and you should be good to go.

Note: You can lay a towel under the sink to catch any spillage of water.

Install Under Sink Water Filter

With a marker pen, mark where you intend to mount your water filter—remembering that we want 30mm (3cm) minimum underneath the system when we remove the housings, and we drop them down to change the cartridges. To be on the safe side, just make sure there is more than enough room underneath. Drill two pilot holes that line up with your water filter bracket. Partly screw your two screws into your pilot holes. Mount your water filter.

It’s as easy as that. Now you are ready to connect your water hose and continue.
