Why Is Dirty Water Coming Out Of Your Sink?

Published on September 29, 2023
Written by kristinia

Have you ever encountered dirty, murky water when turning on the tap for your sink? It can be alarming and confusing; yet why does this occur in so many homes? But what exactly causes this?

The culprit behind dirty water coming out of your sink can be various issues, ranging from rusty pipes to problems with your water heater. However, rest assured that a professional plumber can easily fix most of these problems.

Rusty pipes are a common cause of dirty water. Over time, pipes may corrode, causing rust to mix with your water. This discolors the water and can lead to an unpleasant metallic taste. Moreover, problems with your water heater can also lead to discolored water. Sediment buildup in your water heater can cause your hot tap water to turn a dirty brown color.

If you’re experiencing problems with dirty water coming out of your sink, getting a professional to examine the issue is essential. DIY fixes may seem appealing but often lead to more harm than good.

Dealing with dirty water doesn’t have to be a stressful ordeal. At Full Speed Plumbing in Mount Vernon, WA, our team of experienced plumbers is ready to tackle any plumbing issue you may encounter.

4 Causes of Dirty Sink Water

Given the nature of your plumbing system and the water source, you might encounter dirty water from your sink for several reasons. Here’s a comprehensive list:

Rusty Pipes

Rusty pipes can be the primary culprit behind dirty water. Over time, metal pipes corrode, leading to rust contaminating the water supply and discoloring it with an unpleasant brown hue and metallic taste. 

If your sink’s water appears reddish-brown in color, this could be a telltale sign that your metal piping is rusting away – this may indicate an issue!

Sediment in Water Heater

Sediment buildup in your water heater may also contribute to discolored tap water. 

Over time, mineral deposits form at the bottom of its tank, which, when disturbed, can transform your hot tap water into murky brown hues – in other words, if your sink’s hot tap water appears murky while cold tap water appears clear, then sediment might be the problem!

Issues with Local Water Supply

Sometimes, the source of the problem could lie elsewhere than just in your home. Maintenance or repair work on local water lines could stir up sediment, temporarily discoloring it. You will likely receive a notification from your water provider when this occurs.

Bacterial Contamination

Dirty water may occasionally be due to bacterial contamination. A backflow issue or water source contamination could result in dangerous and dirty drinking water, particularly if your tap water has an unpleasant odor or leads to health issues like stomach upset. In these rare cases, bacteria contamination might be the culprit behind dirty and unsafe drinking water.

Please remember, if you’re unsure about the cause of the dirty water coming out of your sink drain, it’s always best to consult a professional plumber. They can accurately diagnose and resolve the issue, ensuring your water is clean and safe to use.

What Are The Risks of Drinking Dirty Water From Your Sink

Drinking dirty sink water presents several health risks that should not be underestimated. Of particular concern is the risk of ingestion of harmful bacteria or parasites, which can cause diarrhea, nausea, and stomach cramps if taken directly from a tap or other source.

Heavy metals from corroded pipes — like lead — can accumulate in our bodies over time, leading to serious health problems, including kidney damage and developmental delays in children. If water discoloration is due to rust, this could translate to high iron levels, which, while not directly harmful, could contribute to conditions like hemochromatosis among genetically predisposed individuals.

Contaminated water may contain chemical contaminants that pose long-term health risks, including cancer. Before deciding to drink the water in question, always ensure it is clear, odorless, and safe – if uncertain, contact a professional plumber or water authority for guidance.

What Can You Do If Dirty Water is Coming From Your Sink?

Though it might be tempting to attempt fixing your dirty water issue yourself, doing it without previous plumbing experience could prove costly and ineffective. Plumbing systems are intricate systems and should only be handled by certified experts.

By trying to tackle it yourself without proper experience and knowledge, attempting to resolve an issue may lead to further complications that exacerbate its severity. Instead, professional plumbing services like Full Speed Plumbing should always be your go-to option for quick solutions.
