Yes, there is Lead in Your Tap Water in Brisbane

Hot water bath

Updated 2024 by John Salmon

There is lead, everywhere. You encounter it in the air, the soil, dust, some hobbies, some alternative medicines and in aged paint. We used to pump it straight into the air back when “super” petrol was the default. Nowdays, it’s your taps and pipes may also be delivering lead right to your glass. Lead is dangerous. Lead is water soluble. It was also a very popular building material for a long time. There is lead in your tap water. How much lead is the question?

How likely is it that there’s lead in my home’s plumbing?

There is. But, there’s not TONS. In some countries, the levels are far higher than here. Australian law allows for lead to be used in water infrastructure in modern homes. Our water supply is some of the safest in the world but suffers from “first world problems” – including fancy pipes and tapware. Yes. Lead is in your taps, pipes and fittings. The law will change in 2026 to mean plumbing fixtures will be limited to lead levels to below 0.25%. Not zero. Just less. And not all plumbing products. New lead regulations will only impact plumbing fixtures that deliver drinking water, not your shower, bath or irrigation. There are currently products on the market that are certified lead free, if you’re planning a new build, it’s worth investing in these.

How much lead is too much in our drinking water

According to Australian Drinking Water Guidelines, 0.01mg per litre of lead in our drinking water is “safe” (previously the number was 0.05mg per litre). Despite the acknowledgement of lead being unsafe in our water, there is no enforced monitoring of lead contamination in public water supplies on both a local and national level. This makes it all the more important that we are personally diligent in having our water tested for the safety of our families and our communities.

How do I know if a pipe is lead?

If your home was built prior to 1940, you may have pure lead pipes. Lead is soft and silvery in colour. It’s not magnetic. So, if you find a silver coloured pipe, that a magnet won’t stick to, and you can “make a mark” by running a coin across the surface, you may be looking at a piece of lead. Unfortunately, the issue with most homes isn’t that the pipes are pure lead, it’s part of a copper alloy, or used to adjoin pipes. So, to the naked eye, you may not be able to tell. To know for sure you’ll need professional testing.

The Watermark Certification

The Watermark Certification guarantees that the product you’re buying is compliant with the new reduced lead standards. By 2026, heat pump hot water systems, solar hot water systems, electric and gas will all require watermark certification. Currently, all Rheem hot water systems comply with watermark standards.

Tapware and fittings

Brass tapware fittings, so chic, so hip, so retro…. so leaded. Original brass fittings – how very special! While your dream reno may involve fancy antique tapware, it is probably best you use replicas. By current Australian standards, the levels of lead in tapware is monitored. The issue is the influx of cheap plumbing fixtures that “look designer” without the designer price tag. In 2017, 12000 Australians bought tapware from Aldi that contained dangerously high lead levels.

Why lead needs to be removed from water and tapware

Long term exposure to lead can cause a number of significant health issues, especially if you have infants, young children, or pregnant women in the home.

  • Lead exposure has been known to cause damage to the brain
  • The kidneys
  • Red blood cells

The stakes are even higher for young children. Babies and children exposed to lead can suffer from hearing problems as well as mental and physical impairments.

Tips for treating lead in water and tapware

The first and most important step is monitoring your local water quality via the SEQ water website. Anything above 0.01mg per litre is unsafe and unacceptable. You can also contact a Brisbane plumber to get advice on testing and your specific circumstances.
You can also reduce your exposure to lead on a daily basis by:

1. Running your cold water tap for up to 30 seconds

If the cold water tap hasn’t been used for over six hours, allow it to run for up to 30 seconds before using that water for cooking or drinking.

2. Avoid using water from the hot water tap

Lead is more apparent in hot water, so try to avoid drinking or cooking using water from your hot water tap.

3. Don’t “over boil” your water

The longer you allow a pot of water to boil, the more lead you’ll find in your water due to evaporation.

4. Stop using lead-based cookware

Australian-made cookware likely doesn’t contain lead. But cookware from other countries could very easily contain this dangerous neurotoxin.

5. Replace your old pipes and taps

We recommend buying taps that have the Watermark logo on it as these have the highest quality standards. If you have old taps or corroding pipes, contact one of the friendly plumbing experts here at Salmon Plumbing. We’ll take a look at your plumbing system and provide you with helpful recommendations on how we can increase the safety of your drinking water in an easy and affordable way.

6. Install activated charcoal water filtration at home

Not all water filters remove lead. You’ll need a minimum water filtration system rated at NSF53. These are activated charcoal filters. More expensive and complex filters including reverse osmosis and distillation-based filtration systems will also remove lead. Talk to us about the best option for filters for your circumstances.

Have you fallen for these 5 five plumbing myths?

When it comes to saving money on plumbing projects, there is something we think you should know. 

Those same Youtube videos, Pinterest hacks, and family recipes that are keeping your toilet bowl sparkling clean or your house odor-free may be doing more damage than you think. 

As plumbing professionals, we want to make sure you’re not doing more bad than good when it comes to your home or business’ plumbing. So, we’ve decided to bust five popular plumbing myths and show you the right ways to look after your water and sanitation systems. 

Myth 1: You can flush more than toilet paper

One of the most common issues Salmon Plumbers have faced is attending to, what we call, a UTB, a.k.a an Unidentified Toilet Blockage. See, when it comes to your bathroom, there are many things that might appear flushable, but actually they aren’t. 

Objects like paper towels, maxi pads, tampons and makeup remover wipes are not designed to go down the toilet and can easily cause a blockage if they are flushed. 

Nothing except toilet paper, not even flushable wipes, should be flushed down the toilet.

Myth 2: You should use bleaching tablets to clean your toilet

Bleach can be a very effective toilet cleaning agent. However, when left to sit in your toilet for too long (usually more than 10 minutes), it can damage the toilet bowl surface and degrade many of its working parts. 

A drop-in bleach tablet continually releases bleach over an extended period of time. So, by placing this in your bowl and simply walking away, you run the risk of issues above, or in some more serious cases, the complete corrosion of your toilet bowl!

While it may require a more hands-on approach, manual cleaning processes with the occasional inclusion of bleach will help you achieve the safest and best clean for your toilet. 

Myth 3: You only need to think about your pipes when there’s a problem

Hair and shampoo in the shower, food and coffee grounds in the kitchen sink, and more, can all accumulate in your pipes over time. So, while you may not think anything is immediately wrong, the slow build-up of a blockage may mean water could start backing up without warning. 

To avoid issues like these occurring so suddenly, arrange regular inspections of your home or business’ plumbing system. This can help you identify problems before they become costly, and enable you to learn the best tactics for maintenance from the plumbing professionals.

Myth 4: You can flush fish down the toilet

Before sending a fish to the porcelain pet heaven, you need to be certain it is no longer alive. 

Many fish that are flushed can end up surviving their journey through the sewer system. From there they can become oversized and reproduce at alarming rates. This can put a number of natural ecosystems at risk.

Myth 5: You can use drain cleaner to avoid calling a plumber

If you find drains in your home are gurgling or slow to empty, don’t reach for the baking soda and vinegar or drain cleaner right away. It’s actually best to contact a plumber to remove the blockage that is impacting your system.

Liquid drain cleaners, and drain cleaning methods, are not actually that effective at clearing blocked drains. What they are 100% good at, however, is eating away at your pipes and flushing dangerous chemicals out into natural ecosystems. 

Fact: Your local plumber will have the best advice for plumbing issues

When you can, it’s best to call your local plumber if you are facing a problem, or need some advice for care and maintenance. 

By consulting a professional, you can trust that you are taking the best care of your property’s plumbing system.
