Common causes of metallic taste in Riverside water

Metallic tasting water in Riverside usually comes from one of three sources: the city water supply your home’s plumbing or a mix of both. Here is how to tell the difference. The most common plumbing emergencies in La Sierra and how to solve them.

Minerals in the local water supply

Riverside draws much of its water from the Santa Ana River Basin and local groundwater wells. These sources naturally contain minerals like iron manganese and zinc. When water sits in your pipes or gets heated small amounts of these minerals can dissolve and create that metallic flavor. You will often notice the taste more in the morning after water has been sitting in the pipes overnight. How to find a local plumber in Mission Grove who actually answers the phone.

Old galvanized steel pipes

If your home was built before the 1970s there is a good chance it has galvanized steel pipes. Over time the protective zinc coating wears away and the steel starts to rust from the inside out. That rust flakes off into your water supply and gives it a strong metallic taste. You might also see brown or yellow discoloration in your sinks or toilets. Emergency Water Shut-Off Service.

Copper pipe corrosion

Newer homes often use copper pipes which are more durable than steel but still vulnerable to corrosion. If your water is slightly acidic or has low mineral content it can eat away at copper over time. This releases copper ions into the water and creates a sharp metallic taste. In rare cases high copper levels can also cause a blue-green tint on faucets or in the toilet bowl.

Water heater issues

Sometimes the problem is isolated to your hot water. If your water heater is more than ten years old the anode rod inside can wear out. Without that rod the tank can start to corrode and release metallic particles into your hot water only. You will notice the taste most when running the hot tap.

Riverside Public Utilities and local water sources

Riverside Public Utilities (RPU) manages the city’s water supply and publishes an annual water quality report. The 2025 report shows that Riverside’s water hardness ranges from 250 to 400 parts per million (ppm) depending on the source. That is considered moderately hard to very hard water. Hard water itself does not always taste metallic but it can speed up mineral buildup in your plumbing.

RPU also tests for lead and copper as required by the EPA’s Lead and Copper Rule. In the most recent test less than one percent of sampled homes showed lead levels above the EPA action level of fifteen parts per billion. However homes built before 1986 are more likely to have lead solder or older fixtures that could leach small amounts of metal into the water. EPA information on lead in drinking water.

Is metallic tasting water dangerous?

A metallic taste does not always mean your water is unsafe but it can be a warning sign. The EPA sets maximum contaminant levels for many metals because high doses can cause health problems.

Lead: Even low levels of lead can harm children’s developing brains and cause kidney problems in adults. Lead usually enters water through old lead service lines or lead solder in plumbing.

Copper: Small amounts of copper are harmless but high levels can cause stomach pain nausea or liver damage. People with Wilson’s disease are especially sensitive to copper.

Iron and manganese: These are not considered health risks at the levels found in tap water but they can stain laundry and fixtures and make water unpleasant to drink.

The only way to know for sure is to test your water. A simple home test kit can check for common metals but a professional lab test will give you the most accurate results especially if you have an older home.

Yes. Metals like iron and manganese are not absorbed through the skin in harmful amounts. The main concern is drinking the water. If you are worried about skin irritation consider a whole house filter.
