Why Do I Have Brown Tap Water?

Why Do I Have Brown Tap Water the local plumber melbourne

Discovering brown water flowing from your taps can be alarming, unpleasant and unexpected considering Australia has some of the cleanest tap water in the world. While this issue is relatively common, it’s essential to understand the potential causes and the steps you can take to resolve it. Based on our daily experiences and the questions we have received from our fellow locals, our emergency plumbers here at The Local Plumber have created a simple guide as to why your tap water might be brown, how to fix the problem, and when to call in the professionals.

What Are The Causes Of Brown & Dirty Tap Water?

1. Rust and Sediment in Pipes

The most frequent cause of brown tap water is rust and sediment buildup in the pipes. Over time, metal pipes corrode, and this rust can dislodge and mix with the water flowing to your taps. This issue is particularly prevalent in older homes, aged 30+ years that have galvanized iron pipes which are prone to corrosion over time.

2. Disturbances in Water Mains

Our local councils and water authorities work on water mains can also lead to brown water within your taps. When repairs or replacements are made to the main water lines, sediment that has settled over time can be stirred up and enter your home plumbing system. Be sure to check for announcements from your local water council / water authority as to whether or not they are conducting work within your area. If you are unsure who your authority is, you can search your water authority here:

3. Changes in Water Pressure

Sudden changes in water pressure, which can happen due to repairs in the local water system or even after a fire hydrant is used, can dislodge rust and sediment within the pipes. This dislodged material then flows out of your taps as brown water.

4. Hot Water Heater Issues

If brown water is only coming from hot water taps, the problem might be within your hot water heater. Sediment buildup in the tank can rust over time, especially if the water heater is old or hasn’t been regularly maintained. Depending on whether you have a gas or electric hot water system, the average age can vary from 8-15 years.

Are There Any Health Concerns With Brown Tap Water?

Generally, brown tap water caused by rust is not harmful if only a bit is consumed.. However, it can be unappealing and potentially contain other harmful contaminants, depending on the source of the rust and sediment. It’s wise to avoid drinking or cooking with discolored water until the issue is resolved and the water runs clear.

How To Fix Brown Tap Water?

1. Identify the Source

Determine if the brown water is coming from all taps or only specific ones. If it’s isolated to one area, the problem is likely internal plumbing. If the issue is throughout the house, it’s probably related to the main supply.

2. Check for Local Works

Check with your local water authority if there are ongoing works in your area. Local water services usually provide alerts when maintenance work is expected to affect water quality.

3. Flush Your System

Run all taps in your home for about 20 minutes or until the water clears. This can help flush out any rust or sediment that has been dislodged within your pipes.

4. Inspect Your Water Heater

If brown water only appears when you use hot water, inspect your water heater. You might need to flush the tank to remove sediment. If you have an older hot water system and have been noticing issues elsewhere (e.g inconsistent water pressure, loud noises, leaks) then it is extremely likely that you will need to consider a hot water system replacement it if it’s old or heavily corroded. A local plumber will be able to assist repair and replace your system as well as recommend the best suited system for your family’s needs (e.g whether a natural gas or electric system is better suited).

5. Install Filtration Systems

For homes with recurrent brown water issues due to old, corroding pipes, installing whole-house water filters can help. These systems filter out rust and sediment before they reach your taps. Our plumbers can also assist with water filtration installation and our personal recommended brands to install.

When to Call a Professional

If the above steps do not resolve the issue or you are unsure of the source, it’s time to call in your local professional plumber. A licensed plumber can:

  • Inspect your plumbing system with specialized tools.
  • Replace sections of pipe that are corroded.
  • Service or replace an old water heater.
  • Install filtration systems to prevent future occurrences.
