What to Know Before You Install Dual Mixer Tap in Your Kitchen or Bathroom

Installing a dual mixer tap might sound like a small update, but it can make a big difference in how your kitchen or bathroom looks and functions. If you’re thinking about switching to one or replacing an old one, this guide will help you understand what to expect, what to avoid, and when it’s time to call in a professional.

What Is a Dual Mixer Tap?

A dual mixer tap combines hot and cold water into a single stream through one spout. You control the temperature by adjusting a lever or two handles. It’s a clean, modern upgrade that works well in bathrooms, kitchens, and even laundries. Some come with pull-out spray heads, gooseneck designs, or wall-mounted setups. It’s not just about looks; these taps make life more convenient too.

Where Can You Install One?

You can install dual mixer taps just about anywhere you need water.

• Kitchen sinks for better temperature control while cooking or cleaning.
• Bathroom vanities to add a sleek, functional touch.
• Laundry tubs, especially if you’re dealing with hot and cold water usage.
• Even outdoor sinks, if you’re serious about your BBQ setup.

Things to Consider Before Installation

Water Pressure

Before you install a dual mixer tap, make sure your water pressure can handle it. Some mixer taps require medium to high pressure to function correctly. If your pressure is too low, you might end up with a very expensive trickle.

Plumbing Setup

Do you have separate hot and cold pipes? Mixer taps connect to both, so if your setup is outdated, you might need a few pipe adjustments. Also, check whether you’re mounting the tap on a sink or a wall. Each setup needs a slightly different approach.

Sink Compatibility

Not all sinks are created equal. Some have one hole, others have three. Your new mixer tap might not fit your current sink without modifications. If you need to drill a new hole or use a deck plate, it’s better to know that upfront.

Tap Type and Finish.

You’ll find dual mixer taps in chrome, matte black, brushed nickel, and more. Choose something that suits your overall design. Also, decide between single-lever taps and double-handle ones based on personal preference.

Plumbing Regulations

In Australia, there are strict plumbing codes. DIYing beyond a basic replacement could land you in hot water (pun intended). A licensed plumber is not just helpful; in many cases, they’re legally required.

The Installation Process (Step-by-Step)

1. Turn off the water supply to your home or the specific fixture.
2. Remove the old tap carefully without damaging the sink.
3. Clean the mounting surface, removing any debris or old sealant.
4. Position the new mixer tap, lining it up with the mounting holes.
5. Connect the hot and cold hoses tightly but don’t overtighten.
6. Turn the water back on and check for leaks.
7. Test the temperature control to make sure it mixes properly.

If this list made you sweat, you’re not alone. Many people start this process and call a plumber halfway through. That’s fine! Better safe than soaked.

Common Mistakes to Avoid

• Skipping the pressure check and ending up with weak flow.
• Buying a tap that doesn’t fit your current sink.
• Overtightening connections, which can lead to leaks.
• Using the wrong tools or forgetting plumber’s tape.
• DIY without checking regulations or shutting off the water.

If you’re not 100% confident, this is one of those jobs where it’s okay to call in the cavalry.
