3 Way Mixer Tap - Gooseneck

A 3-way kitchen mixer tap (also called a three way tap or tri-flow tap) is a special kitchen faucet that delivers hot, cold, and filtered water all from a single tap. It combines your ordinary hot/cold mixer with a drinking water filter tap in one sleek unit.

Providing you with pure filtered water on demand alongside regular tap water, without needing a second faucet on your sink. The one tap does it all – giving you hot, cold, and great-tasting filtered water in a convenient, space-saving design.

Installing a 3-way mixer tap is very similar to installing any standard kitchen mixer tap – it fits into the same single hole and comes with flexible hoses for connection​.

In terms of basic steps, it involves: removing the old tap, inserting the new tap assembly, and connecting the hot, cold, and filter lines. Technically, a confident DIYer could handle the physical installation, since the tap uses standard 1/2″ BSP plumbing connections for hot and cold and a 1/4″ tube for the filter line (which are standard sizes in Australia)​. Our Taps come with all necessary hoses and fittings for hookup.

However, Australian regulations require licensed plumbers to install any tap connected to mains water​

For safety and compliance (and to ensure your warranty remains valid), it’s recommended to have a licensed plumber install the 3-way tap. A professional will ensure all connections are secure and meet local plumbing standards. Using a plumber guarantees the installation is done correctly and legally – in fact, many manufacturers advise professional installation to comply with regulations​.

So while it’s physically possible to do it yourself, your best bet is to use a qualified plumber for this job.

Our Three-way mixer taps use separate internal waterways and controls for each water source. Typically, the taps have dual handles: one lever mixes hot and cold water as usual, while a second smaller lever dispenses filtered water.

Inside the faucet, there are independent channels so the purified water never mixes with the mains water, keeping your drinking water pure. When you turn the filtered water handle, water from your under-sink filter flows through its own outlet in the spout. The hot/cold lever operates the regular tap water. Both streams exit through the same faucet spout but are completely isolated internally, ensuring the filtered water remains fresh and uncontaminated. Despite the extra functionality, a 3-way mixer tap installs much like a standard kitchen mixer and uses the incoming water pressure – no electrical pump is needed.

• A 3-way tap combines your filter tap with your main tap, so you don’t have to drill an additional hole or clutter your sink with multiple faucets. This keeps your countertop clean and streamlined.
  
• Get filtered water straight from your main tap whenever you need it – for drinking, cooking, or filling the kettle – without reaching for a second tap. It’s all in one spot, making it very user-friendly for the whole family.
  
• The filtered water outlet in a 3-way tap is isolated, meaning your drinking water stays pure until it reaches your glass. There’s no risk of cross-contamination from the hot/cold tap water. Also, our 3-way taps are made from safe, lead-free materials Food Grade Stainless Steel.
• You’ll save counter top space and the cost of installing and maintaining an entirely separate faucet. One good 3-in-1 tap can often be more cost-effective and easier to install than adding a second fixture.
  

In short, a three way kitchen mixer tap gives you all the advantages of a filter tap with none of the clutter, making it a popular choice for Australian homes that want both style and filtered water convenience.

Our Three-way taps are built with materials chosen for safety, durability, and corrosion resistance. They all use 304-grade stainless steel – also known as food-grade or commercial grade 304 stainless.

This is a high-quality stainless steel that is lead-free, rust-resistant, and hygienic, ideal for drinking water. Our 3-way mixer are made completely from 304 stainless steel, inside and out, so water contacts only smooth steel surfaces. This ensures no metallic taste and no leaching of unwanted elements.

Our 3 Way Mixers also feature PVD anti-corrosion finishes for colored options – PVD coating adds a scratch-resistant layer and vibrant color (matte black, gold, gunmetal, etc.) that won’t chip or peel easily.

You can connect virtually any under-sink water filter system to our 3-way mixer taps, as long as it has a dedicated tubing outlet for dispensing the filtered water. These taps are very versatile and compatible with most common filtration setups.

Overall, as long as your filter system outputs to a tube that can connect to the tap (most use 1/4″ which is the industry standard), you’re good to go. Our 3-way taps, for example, can be fitted to any under-sink filter system using the default 1/4″ tubing, and we offer adapters for 3/8″ or other sizes to suit brands like Brita, if needed. This means you’re not tied to a specific filter brand – you can use these taps with existing filters or new systems of your choice. It’s one of the reasons they’re so convenient.

Yes – a 3-way mixer tap will fit standard kitchen sinks and countertops. Our taps are designed to replace your existing kitchen mixer. They use the same standard mounting hole (generally 35mm in diameter) that most modern sinks have for faucets. You won’t need to drill any new holes if you’re swapping out a normal mixer tap. The underside of the 3-way tap typically has a threaded shank that goes through the sink, secured by a nut and plate, just like any other sink mixer installation.

The taps come with all necessary hoses and fittings for connection. You’ll usually get two flexible braided hoses for hot and cold water (standard 1/2" BSP connections to your inlet valves) and a separate smaller tube or hose for the filtered water connection. This filtered water hose connects to your under-sink filter’s outlet (often 1/4" tubing). If your filter uses a different size (like 3/8" or 1/2"), many 3-way taps include or have available adaptors to suit various tubing sizes. The installation process is very similar to any mixer tap: you feed the hoses through the sink hole, tighten the tap from underneath, and connect the hoses to your water lines and filter line.
