How to remove scale from electric water heater

Electric water heaters need to be cleaned regularly, otherwise a lot of scale will easily accumulate on them. Don't underestimate scale. In fact, such a problem is not good for our health and the life of the electric water heater. So what kind of cleaning method should be chosen for electric water heaters? Let's take a closer look at these methods.

The simplest way is to remove the water inlet and outlet pipes, gently shake the body to let the water in the inner tank flow out; then fill it with water again to clean it, and repeat this three or four times.

Before cleaning, the water temperature of the electric water heater should be below 50°C. At this temperature, the water can be discharged directly into the sewer pipe without affecting the pipe.

It is best to deep clean the storage type electric water heater once every three years.

1. Open the seal of the water heater and replace the magnesium rod inside the electric water heater. The function of the magnesium rod is to reduce the corrosion of the heating tube and cause the scale to produce a chemical reaction. The magnesium rod used for a long time will produce flocs or lumps wrapping the rod surface until the magnesium rod is completely consumed. Therefore, if you use the electric water heater for a long time, it is best to replace the magnesium rod with a new one in time, otherwise it will easily leak water and electricity.

2. Remove the limiting device of the pressure relief valve wrench (usually a component with a plastic square hole, a safety piece used to prevent the pressure relief valve from being accidentally opened), and use a plastic tube to connect the small tube at the pressure relief port of the pressure relief valve to draw out the water in the inner tank; turn the pressure relief valve wrench 90 degrees from the vertical position, and the pressure relief valve has been opened.
