Hard Water and Your Water Heater

Modern water heaters are built to endure, and they will resist corrosion and other damage for many years, provided that they receive annual maintenance visits from professionals. However, one factor in your home that may threaten your water heater with damage and even an early replacement is hard water coming from the municipal supply. This is a serious issue, and if it’s occurring in your home you should contact Saddleback Plumbing right away. We not only provide excellent repair service for water heaters in Orange County, but we can also install water softeners to eliminate hard water trouble.

Why hard water is a problem for water heaters

Hard water is water that contains a high amount of minerals suspended in it, principally magnesium and calcium. These minerals often enter the water supply on its way from the municipal treatment plant through ground water seepage. Hard water is almost never harmful to drink, but it can cause major issues for your home’s plumbing and its water heater.

The high temperatures inside a water heater tank will create a substance called limescale from the minerals inside hard water. Limescale will begin to build up along the inside of the tank. Because limescale acts as an insulator, it will prevent heat from escaping naturally from the tank. The result is a temperature imbalance inside the water heater that will often lead to overheating and high pressure that can damage the system. In addition, limescale deposits will start to block valves and connections in the water heater, creating additional pressure problems that can lead to leaking.

Repair technicians can de-scale a tank to remove the deposits from hard water and restore the water heater. However, if you are encountering hard water issues, you will need to go a step further and get to the root of the problem with the installation of a whole-house water softener. This will both protect your water heater and the rest of your plumbing, which will suffer from calcite deposits in the piping that will create spikes in water pressure.

If you are experiencing trouble with your water heater due to hard water, give us a call right away.
