How Hard Water Affects Your Water Heater

What Is Hard Water and Why Does It Matter?

Hard water is a common issue in many parts of the country, including Texas. It occurs when groundwater absorbs minerals from rocks and soil, such as calcium, magnesium, iron, and sulfur. These minerals can form deposits or scale in your pipes, appliances, and fixtures, reducing their efficiency, lifespan, and performance. 

Hard water can also affect the taste and appearance of your water, leaving a chalky or cloudy residue and making it harder for soap or shampoo to create a good lather.

How Does Hard Water Affect Your Water Heater?

If your water heater is exposed to hard water for prolonged periods, several problems can occur, including:

Mineral Buildup

Hard water can leave behind mineral deposits or scale inside your water heater tank and on the heating elements, reducing its capacity and efficiency. This can lead to higher energy bills, longer heating times, and a reduced hot water supply.

Corrosion

Hard water can also corrode the metal parts of your water heater, such as the anode rod, the tank, and the pipes. Corrosion can cause leaks, rust, or even cause your water heater to fail, requiring costly repairs or replacement.

Sediment Accumulation

Hard water can carry sediments like sand, dirt, or rust which can settle at the bottom of your tank and cause sediment buildup. This can reduce the amount of hot water available and clog the drain valve, leading to leaks or bursts.

What Can You Do To Prevent or Mitigate Hard Water Damage to Your Water Heater?

Minimize the impact of hard water and avoid needing water heater repair by:

Installing a Water Softener

A water softener removes the minerals from hard water and replaces them with sodium ions or potassium ions, making the water "soft."

Soft water is less likely to cause mineral buildup or corrosion in your water heater, and it can improve the taste and feel of your water. First Service offers a variety of water softener options that can fit your budget and needs.

Flushing Your Water Heater

Flushing your water heater regularly can help remove the sediment buildup and prolong the lifespan of your water heater. At First Service, we recommend that our clients flush their water heaters at least once a year, or more frequently if they have hard water or use hot water heavily.

Checking Your Anode Rod

An anode rod is a metal rod that collects corrosive materials from water and protects the tank against leaks and rust. However, if the anode rod is used up or corroded, it won’t function properly and your water heater is at greater risk of damage. First Service can inspect and replace your anode rod if necessary.

Monitoring Your Water Pressure

High water pressure can also contribute to the wear and tear of your water heater, especially if you have hard water. First Service can install a pressure regulator to maintain the optimal water pressure for your plumbing system and water heater.
