Is Your Tap Water Safe? When a Water Filter Becomes Essential

Most of us don’t think twice about filling a glass from the tap. After all, Australia’s water supply is some of the best in the world, right? 

But while our water treatment systems are impressive, they’re not perfect. Depending on where you live and how old your plumbing is, what comes out of your tap might not be as clean as you think.

From chlorine and sediment to lead and microplastics, there are plenty of things that can sneak into your tap water. The good news is, a water filter can deal with most of them—if you know what to look for.

So, let’s dive into what might be lurking in your tap water, how to spot the signs it’s not as clean as it should be, and when it’s time to consider a water filter.

What might be lurking in your tap water?

Australia’s tap water is generally safe to drink, but that doesn’t mean it’s perfect. Water is treated before it reaches your tap, but it has to travel through a lot of pipes to get there—and that’s where things can get complicated.

Here are a few of the usual suspects that can find their way into your tap water:

  • Chlorine: Added to kill bacteria, but it can leave water tasting and smelling like a swimming pool.
  • Sediment: Things like rust, sand, or dirt can break off from older pipes, especially if you live in an older home.
  • Heavy metals: Lead, copper, and mercury can leach into water from old pipes or fixtures. Even at low levels, they’re not something you want in your drinking water.
  • Microplastics: Tiny particles that can get into water supplies from plastic pipes, packaging, or even washing synthetic clothes.
  • Fluoride: Added to prevent tooth decay, but some people prefer to filter it out.

 Most of these aren’t dangerous in small amounts, but if you’re noticing any off tastes, smells, or even cloudiness in your water, it might be time to take a closer look.

Signs your tap water might need some help

If you’ve ever filled up a glass of water only to hesitate before drinking it, you’re not alone. Sometimes, it’s obvious that something’s off—like a metallic taste, a weird smell, or water that’s a bit too cloudy for comfort.

Here are a few signs that your tap water might need some extra help:

  • It smells like a swimming pool: A slight chlorine smell is normal, but if it’s strong enough to notice, that’s a red flag.
  • It tastes metallic or bitter: This can be a sign of heavy metals like lead or copper, especially if you live in an older home.
  • It’s cloudy or has particles floating in it: Sediment can make water look milky or leave bits floating around.
  • You’ve got stained sinks or appliances: Brown or reddish stains can mean high iron levels, while blue or green stains can point to copper.
  • Frequent stomach upsets: Sometimes, low levels of bacteria or parasites can slip through water treatment—especially after heavy rain or pipe work in your area.

If any of these sound familiar, it’s worth getting your water tested to find out what’s actually in it. A professional test can check for everything from chlorine and heavy metals to bacteria and pesticides, giving you a clear idea of what needs filtering.

When a water filter goes from “nice-to-have” to “essential”

A water filter can do a lot more than just improve the taste of your water—it can actually make it safer to drink. But when does it go from being a nice extra to a must-have?

  • If you live in an older home: Houses built before the 1980s often have lead pipes or solder, which can leach into your water. A filter that removes heavy metals is a smart move.
  • If you’re on tank or bore water: Without treatment, tank or bore water can carry bacteria, sediment, and even pesticides. A UV filter combined with a sediment filter can make it safe to drink.
  • If you have a compromised immune system: Certain bacteria or parasites that sometimes slip through water treatment can pose a bigger risk if your immune system isn’t 100%.
  • After floods or heavy rain: Extreme weather can overwhelm water treatment systems, letting bacteria or sediment through. A filter can catch these contaminants before they reach your glass.

Even if none of these apply, installing a simple under-sink or tap filter can give you peace of mind—and make your water taste a whole lot better.

Choosing the right filter for your needs

Not all water filters are created equal, so it’s important to choose one that deals with the specific problems in your water. Here’s a quick guide to what different types of filters can do:

  • Carbon filters: Great for removing chlorine, chemicals, and some heavy metals. They also improve taste and smell.
  • Reverse osmosis: One of the most thorough options, removing almost everything—including fluoride, lead, bacteria, and microplastics.
  • UV filters: Ideal for tank or bore water, these zap bacteria and viruses without using chemicals.
  • Sediment filters: Useful if your water has visible particles or if you live in an area with older pipes.

If you’re not sure which one to go for, getting your water tested first can help you pick the right filter without wasting money on one that doesn’t solve your problem.

Keeping your filter in top shape

Buying a water filter isn’t a set-and-forget kind of deal. To keep it working properly, you’ll need to replace the cartridges or membranes regularly—usually every six to 12 months, depending on the type and how much water you use.

For reverse osmosis systems, don’t forget to replace the pre-filters too. If these get clogged, they can reduce water pressure and leave contaminants behind. And if you’ve got a UV filter, keep an eye on the bulb—it usually needs replacing once a year to keep zapping bacteria effectively.

Following the manufacturer’s instructions for maintenance might seem like a hassle, but it’s a lot easier (and cheaper) than dealing with a clogged filter or drinking contaminated water.

Is a water filter worth it?

At the end of the day, whether or not you need a water filter comes down to what’s in your water and how comfortable you are drinking it. For some people, the taste of chlorine is reason enough to get a filter; for others, it’s about making sure there are no heavy metals, bacteria, or microplastics getting through.

If you’re noticing any off tastes, smells, or even just want a bit more peace of mind, it’s worth looking into a water filter. Even a basic carbon filter can make a noticeable difference—without costing a fortune.

And if you’re not sure where to start, a quick chat with a plumber can help you figure out what’s in your water and what kind of filter makes sense.

What are the three most common types of plumbing in a home?
  1. Water Supply Lines:
    Carry drinking water from the mains to faucets, showers, toilets, and other points of use.
  2. Drain, Waste, and Vent (DWV) System:
    Removes wastewater and gases from the sewer system, properly venting them to the outdoors.
  3. Gas Lines:
    Distribute natural gas or propane to appliances such as stoves, water heaters, and space heaters.

1- Pipes:

  • Copper: Durable and corrosion-resistant. It is ideal for hot and cold water.
  • PVC (Polyvinyl Chloride): It is inexpensive and common in cold water and drainage systems.
  • PEX (Cross-linked polyethylene): It is a flexible and easy-to-install material. It is suitable for hot and cold water.
  • Galvanized steel: It was once commonly used, but is now being replaced due to its tendency to corrode.
  • ABS (Acrylonitrile Butadiene Styrene): This black plastic pipe is used in drains and ventilation.
  • CPVC (Chlorinated PVC): It is very similar to PVC, but it resists high temperatures. It is very useful for hot water.
  • Stainless steel: This type of pipe is highly resistant to corrosion and can be used in a variety of ways in the home.
  • Black pipe: This is used for gas lines.

 

2- Fittings:

  • Elbows: These change the direction of water flow.
  • Couplings: Used to join two straight sections of pipe.
  • Tees: Create a branch or branch in the line.
  • Reducers: Used to connect pipes of different sizes.
  • Unions: These facilitate easy disassembly.
  • Bushings: Help reduce a larger pipe to a smaller one.
  • Adapters: These allow connecting pipes of different materials.
  • Caps: Allow the end of a pipe to be sealed.
  • Plugs: Allows the sealing of a threaded opening.
  • Flanges: Help connect pipes to equipment or systems.
