Which Tap Is Right for You?
Which Tap Is Right for You?
Which Tap Is Right for You?
You’ll need a way to dispense your RO water. The P500 gives you two options:
Option 1: 3-Way Mixer Tap
- Connects directly to a 3-way kitchen tap (hot, cold mains water + pure water).
- No extra faucet hole needed.
- Choose from our premium finishes or use your existing 3-way tap.
- Kit includes all fittings to hook it up.
Option 2: Dedicated Dual-Function Faucet (Included)
- Comes standard with the P500.
- Two outlets:
• Filtered water (basic chlorine/sediment reduction)
• Purified water (full RO + remineralization) - Installs in a 28mm sink/counter hole (like a soap dispenser).
Already have a filtered tap or 3-way mixer?
Simply connect the P500 to it and use it for purified water only.

P500 Tankless Reverse Osmosis System – Includes Standard Dual Tap
Trusted By
Australia's Only WaterMark Certified Tankless RO System
You want peace of mind about what your family drinks. Not more research. Not more worry. Just clean, safe water.
The P500 is Australia's only WaterMark-certified tankless system. It actually works. No bulky storage tanks and fits under tight sinks.
Your tap water won't taste like a pool anymore. It'll be fresh and clean. The kids will drink more water and you'll stop buying plastic bottles.
You've looked into this long enough. This is your answer.
What the P500 Actually Removes
98%
PFAS & PFOS "Forever Chemicals"
97%
Fluoride
99%
Chlorine (Taste & Odor)
98%
Lead, Arsenic, Mercury (Heavy Metals)
99%
Micro Plastics
You're Already Protecting Your Family. Just Do It Better
Right now, you're spending $2,800 a year on bottled water to avoid tap contaminants. But you're trading one problem for another: microplastics.
Every plastic bottle leaches up to 240,000 particles per liter into your family's water. The P500 removes 99.7% of microplastics AND the tap water contaminants you're already worried about.
Better protection. No plastic waste.
Fits Where Traditional RO Systems Can't
Traditional tank based RO systems crowd your cabinet and make you wait. The P500 gives you faster consistent flow (500 GPD vs 50 GPD) in 60% less space and you never wait for a tank to refill.
The freestanding design means no mounting brackets, no drilling into your cabinet. Stand it upright in a standard cabinet or lay it flat for low clearance spaces. Position it wherever it fits best, then move it if you need to.
From invisible contaminants to complete confidence
Seven stages of filtration remove: chlorine that affects taste, PFAS and heavy metals that threaten health, and minerals that damage appliances.
The RO membrane captures 99% of contaminants down to 0.0001 microns. Then the alkaline remineralization stage adds calcium and magnesium back, pure water that actually tastes good.
The result? Water your family trusts and chooses. Coffee that tastes right. Kids who drink more water because it doesn't taste like chemicals.
Pure Water, Not Empty Water
Traditional RO removes everything, including beneficial minerals. The P500 adds them back.
The alkaline remineralization stage restores calcium, magnesium, and potassium your body needs, then balances the pH to 7.5-8.5. The result? Water that's pure but not stripped. Clean but not acidic. Healthy and actually tastes good.
No flat, "dead" water. Just crisp, alkaline water your family chooses to drink.
30 Second Filter Changes No Tools No Mess
Transparent maintenance costs. Smart reminders. Nothing hidden.
Twist off, twist on cartridges. 30 seconds to swap. No tools, no call outs required.
Annual cost: ~$299 that's $2,500 less than bottled water.
Smart alerts remind you. Filters ship to your door. You never think about it.
Your Way: 30 Minute DIY or Professional Installation
Tap requirement: The P500 requires a dedicated tap. Use the included dual function tap (28mm hole) or connect to an existing 3-way mixer tap. It cannot connect to standard kitchen taps.
Seven step installation: mount feed adaptor (3/8" tubing), drill and install faucet (28mm hole), attach drain clamp, connect four water ports, plug in power, flush system
DIY install: 30-45 minutes with wrench and drill. Or hire any plumber ($150-300 typical).

Got Questions?
How often do I change the filters & which ones?
How often do I change the filters & which ones?
The P500 uses 3 filters with different lifespans:
- Every 6 months: PPC filter (catches dirt, rust, chlorine)
- Every 12 months: T33 filter (adds minerals, makes water alkaline)
- Every 24 months: RO membrane (removes heavy metals, fluoride, PFAS)
Don't worry about tracking dates, the system's smart alerts tell you exactly when each filter needs changing.
Changing filters is ridiculously easy: Just twist off the old one, twist on the new one. Takes 30 seconds, no tools needed.
How will I know it's time to replace the filters?
How will I know it's time to replace the filters?
The system tells you automatically.
The filter replacement is based on a preset time schedule. The P500 system automatically notifies you when each filter is due for replacement. There’s no need to manually track dates, the system is programmed with smart filter alerts that remind you when it’s time to change each filter.
Simple as that, you'll know exactly when to change each filter without thinking about it.
Where can I buy replacement filters?
Where can I buy replacement filters?
Directly from AQUALA.
Order replacement filters through our website, give us a call, or contact our support team. We keep all filters in stock for fast delivery across Australia.
Easy reordering, no hunting around for compatible filters from random suppliers.
Can I use my existing tap or do I need a separate faucet?
Can I use my existing tap or do I need a separate faucet?
You need a separate tap for your filtered water. Two easy options:
Option 1: Use a 3-Way Mixer Tap
If you have (or want) a 3-way kitchen tap, the P500 connects directly to it. No extra holes needed, your existing mixer dispenses pure water alongside hot and cold mains water.
We sell matching 3-way taps in various finishes, or you can use your existing one. The kit includes all connectors to hook it up.
Option 2: Dedicated Dual-Function Faucet (Included)
The P500 comes with a sleek dedicated faucet that gives you:
- Filtered water: For dishes and general use (basic filtration, only goes through the first stage)
- Purified water: For drinking and cooking (full RO treatment)
Installation: Just drill a 28mm hole in your sink (like installing a soap dispenser) and secure the faucet. Takes minutes.
Already have a filtered water tap or 3 way tap? Connect the P500 to it and use it for pure water only.
How does reverse osmosis work?
How does reverse osmosis work?
Reverse osmosis pushes water through an ultra-fine membrane that blocks contaminants.
Think of it like the world's finest screen, only pure water molecules can pass through, while PFAS, fluoride, heavy metals, and other nasties get flushed away.
Here's what makes tankless different: Traditional RO systems filter water slowly and store it in a tank. The P500 filters water instantly as you use it, no storage, no waiting, always fresh.
The system uses pressure to force water through the 0.0001-micron membrane (that's 500 times finer than a human hair), then adds healthy minerals back before it reaches your tap.
