How to Find the Source of Rusty Water

Rusty water flowing from your home taps can be both concerning and inconvenient. EPS Hawaii, Oahu and Hawaii Island’s trusted plumbing experts, can help shed light on this issue. Here we have put together a guide to help homeowners identify the source of rusty water and how to address the problem to keep a healthy and safe home.

How to Find the Source of Rusty Water

What is Rust?

Rusty water is often caused by the presence of iron in your plumbing system. When iron particles oxidize, they form rust, lending the water its distinctive reddish-brown hue. While generally not harmful to your health, it can stain laundry, dishes, and fixtures, and may indicate underlying plumbing complications.

Locating the Source of Rusty Water 

1. Check Your Water Heater    

Start with your water heater. Rust can accumulate within the tank over time, causing discolored water. Drain a few gallons from the heater into a bucket – if the water clears up, the water heater is likely the source.

2. Inspect Pipes

Corroded pipes, especially if they are old and made of iron or galvanized steel, can contribute to rusty water. Examine visible pipes for signs of rust or corrosion. Discolored water is often more noticeable when first turning on the tap in the morning.

3. Examine Faucet Aerators and Screens

Mineral buildup in faucet aerators and screens can also lead to rusty water. Unscrew the aerator or screen and inspect for rust particles. Cleaning or replacing these components can improve water quality.

4. External Factors

Occasionally, rusty water may stem from issues outside your home. Municipal water supplies or changes in water pressure can stir up sediment in pipes, causing temporary discoloration. Contact your local water utility provider if you suspect this is the case.

5. Seek Professional Assistance

If you’re unable to identify the source or the issue persists, it’s time to call in the experts. EPS Hawaii’s skilled plumbers can conduct a thorough inspection, pinpoint the cause of rusty water, and recommend appropriate solutions.

Addressing Rusty Water

Depending on the source, solutions may include:

  • Flushing your water heater to remove sediment.
  • Repiping sections with corroded pipes.
  • Installing a water filtration system to prevent rust particles from reaching your taps.

Preventing Future Rusty Water

Regular maintenance and preventive measures can reduce the likelihood of rusty water. Consider:

  • Upgrading to corrosion-resistant pipes.
  • Flushing your water heater annually.
  • Installing a whole-house water filtration system.
