In this next video, we'll show you the best way to install a whole house water filter. We have a quick look at a typical suburban house and show you the ideal place to put the water filter – that’s after your reticulation system (your sprinklers and irrigation). This way, your household water stays nice and clean, while your garden watering system isn't affected.

Learn how to easily set up your filter so it works its best and keeps your water supply free from contaminants. This is helpful for homeowners who want to improve their water quality without messing up their garden or outdoor setups.

1. First things first, assess the location where your whole house big blue filter system is going to be installed. You're looking for a good position where you can fix the filter securely.

2. The bracket on your whole house big blue filter system has two x holes for attaching it to the wall. Use some decent, strong screws or bolts to fix the water filter onto the wall or a frame.

3. Ideally, you want to mount the whole house big blue filter system on a solid house wall. If you're using a frame, make sure you concrete that frame into the ground good and proper. This system gets pretty heavy when it's full of water, so you need to make sure it's anchored to something strong enough to handle whatever the weather throws at it – even a cyclone, if you're in that sort of area!

4. Now, set up your whole house big blue filter so the water flows through it in the right direction. The caps will be marked "In" and "Out" on the top of the housing, or it might just be left to right. These systems come already put together. But, if your water needs to flow from right to left, you'll have to take the bracket off the system, spin it around 180 degrees, and then reconnect it.

5. The inlet pipe (where the water comes in) will attach to the "In" port on your filter system. The outlet pipe (where the clean water comes out) from the whole house big blue filter system will connect to your home's water system via the "Out" port. Now's also the time you might want to install a bypass pipe and shutoff valve, as well as shutoff valves and gauges for the inlet and outlet.

PLEASE NOTE: Whatever you do, do not use any sealants on any of the threads. They can expand and cause cracks, which will wreck the whole house black caps. Please, only use proper thread tape.

6. Once it's all installed, don't turn the main water valve on just yet. Go and fully open an outside tap that's closest to where you've put the whole house big blue filter system.

7. Now, slowly open the valve on your main water line and let the whole house big blue filter system fill up with water. Once it's full, water will start flowing out of that open tap nearby. Let the water run for a good 10 minutes before you use it for anything else.

Just a heads-up, when you first turn it on, you'll get some black water coming out from the carbon filter. You might want to catch this first lot of black water in a bucket, as it’ll be pretty dark from the carbon.

8. As the whole house big blue filter system is filling up, push the red air bleeder buttons on top of the filter housings. This lets out any air that's got trapped inside. You want to make sure there are no air pockets stuck in there.

9. Have a good look around the housing for any leaks. If you spot any, you'll need to fix them up.

IMPORTANT: PLEASE DO NOT USE ANY KIND OF SEALANT on the threads of this water filter. ONLY use plumber's thread tape. If you use sealants, they can expand after the filter's connected and can crack the inlet and outlet ports, which can cause leaks within a day or so. Make sure you tell your plumber or whoever's installing it that they cannot use a sealant.

The minimum working pressure you'll need really depends on what type of cartridge you've got inside your water filter. Sediment cartridges don't usually slow the water flow down much, unless they're blocked with sediments. But a fine micron carbon block cartridge can need a bit of pressure to push the water through it.

Your typical suburban water pressure should be fine. The maximum working pressure is around the 80 psi mark. If your pressure is higher than 80 psi, you need to install a pressure limiting valve before the water filter. This will stop any excess pressure from being forced into the system and causing damage.

Please take care when you're installing the gauges. Only use plumber's thread tape on the gauge thread – no sealant! Make sure the threads haven't crossed and tighten the gauges up until they're tight.

If any of the gauge threads seem a bit tight as you're screwing them in, just turn the gauge forward as far as it'll comfortably go without forcing it, then turn it back the other way to loosen it a bit. Then, try turning the gauge forward again until you've got it installed how you need it.

IMPORTANT: DO NOT USE ANY SEALANT ON THE GAUGE THREADS. Use thread tape only!

PLEASE NOTE: These water filters are set up for the water to flow from left to right. If you need your water filter to flow the other way (right to left), you'll have to take the bracket off and spin it around 180 degrees. Then, refit the bracket so that once it's all installed, the whole water filter housing is set up correctly for your flow.

PLEASE NOTE: The GRANDER® unit can be installed right after the whole house filter for maximum water treatment. Please see the Grander Installation information in the email & inside the box.

This video shows you how easy it is to swap out the filters in your whole house water filtration system. You'll learn the step-by-step way to do it, so you can keep enjoying chlorine-free water and avoid issues like red eyes and skin irritation.

With just a few minutes of maintenance each year, you can have cleaner, healthier water all through your home. This is perfect for homeowners who want to keep their filtration system in top shape without any fuss.

1. First up, turn off the water supply.

2. Open a tap that's closest to the whole house big blue filter and let all the pressure empty out through the tap.

3. Use the supplied housing opening tool to take off the housing. You'll turn it anti-clockwise (to the left).

4. Once you've loosened it with the tool, you should be able to unscrew the housing by hand. Just keep spinning it anti-clockwise until the housing comes right off.

NOTE: If you haven't let all the pressure out, the filter housing will be hard to loosen. It's absolutely vital that you release the water pressure before you try to take the filter housing off.

5. Take out the old filter and discard it. Make sure you take note of which way the cartridges were sitting.

6. Install the new whole house big blue cartridges into the filter housings.

NOTE: While you're changing the cartridges, it's a good chance to do a bit of preventative maintenance. Lubricate the o-ring and the housing threads with food-grade silicone grease.

7. Make sure the centre hole of the cartridges is sitting properly on the stump in the base of each housing. Check that the cartridge is centred and standing straight up as you lift the housing back up to screw it into the head cap. Use one hand under the housing to support it as you screw the whole house big blue filter housing back on by turning it clockwise (to the right). Keep going until it's hand-tight. If you've lubricated it properly, it should screw on nice and easy without needing the tool.

8. Now, put the housing tool onto the filter housing. Tighten the filter housing until it's firm. Don't go overboard and overtighten it. Don't force it.

9. Don't open the main valve just yet. Fully open the tap nearest to the whole house water filter again.

10. Slowly open the valve on the main line and let the water flow. Once the housings are full of water, press the red air bleeder buttons on top of the filter housings again to let out any air that's trapped inside the whole house big blue filter system. This makes sure no air pockets are stuck in there.

11. Let the water flow out of that open tap nearest to the water filter for a good 10 minutes. This is to flush out all the black water from the new carbon cartridges until the water runs clear again. You might want to catch that first bit of water in a bucket, as it can be black from the carbon fines in the new cartridges.

12. Turn off the flushing tap. Then, go inside and turn on some taps in your house to release any air that might be in the pipes. And you're done! Have a final check around the work area to make sure there are no leaks and everything looks as it should. Clean up the area, and you're all set for beautifully filtered water.
