Booking in a water filter installation can feel like a bit of an unknown if you’ve never had one done before. How long does it take? Does it involve cutting into your pipes? Will you be without water for the day? Here’s a straightforward walkthrough of what installing a whole house filtration system in a Perth home actually involves.
Before the Installer Arrives
Most reputable installers will do a quick assessment of your home before the install date — either in person or based on photos and details you provide. This is to confirm where your main water line enters the property, the type and size of the pipework, and the best location for the filtration unit itself.
Common installation spots include the garage, an external wall near where the main line enters the house, or a dedicated utility area. The unit needs to be installed before any branch lines split off to other parts of the house, so every tap benefits from filtered water.
On Installation Day
A typical whole house filtration installation takes a few hours for a straightforward setup, longer if the plumbing configuration is more complex or if additional work (like relocating pipework) is required.
Your water will need to be turned off for part of the installation while the system is plumbed into the main line. A good installer will let you know roughly how long to expect this for, so you can plan around it — usually it’s a matter of a few hours rather than a full day.
What Happens to the Existing Plumbing?
The filtration system is plumbed directly into your home’s main water line, typically with a bypass valve included. This bypass is a handy feature — it means if you ever need to do maintenance on the filter, or in the rare case something needs troubleshooting, water can still flow through the bypass while the system is being looked at.
Your installer should also fit appropriate isolation valves so the filtration unit can be serviced without needing to shut off water to the entire house.
After Installation
Once the water filter installation is complete, most installers will run the system through for a period to flush out the new filter media before water reaches your taps. You might notice a very slight initial taste or clarity difference in the first day or so as the system settles in — this is completely normal and resolves quickly.
You’ll usually be given documentation on filter change intervals and what to look out for, plus contact details for any follow-up questions.
Common Questions About Installation
A few things people often ask: Yes, your existing hot water system and appliances are compatible with a filtration system being added — it simply treats the water before it reaches them. No, you don’t need any special plumbing modifications beyond what the installer brings with them. And generally, no permits are required for a standard whole-home filtration install in most residential settings, though it’s worth confirming this with your installer if you have any unusual plumbing setup.
