When using a hot and cold water tank, the device may encounter issues such as unusual loud noises. While not as dangerous as electrical leaks, it can still impact the durability and lifespan of the hot and cold water tank. Let's explore the reasons and remedies for a noisy hot and cold water tank in the following article with Mytour!
1. Causes of Noisy Hot and Cold Water Tanks
1.1. Impure Water Supply for the Hot and Cold Water Tank
The issue of a noisy hot and cold water tank can occur in both direct and indirect types due to an impure water supply. The water contains natural minerals such as calcium, magnesium, etc. When heated, these minerals are prone to precipitate and adhere to the tank walls.
After the water cools down, these minerals will sink to the bottom. When the machine is turned back on, they will collide with the tank walls, creating noise. Not only that, but it also leads to significant energy wastage during the use of the hot and cold water tank.

1.2. Error from Pressure Reducing Valve
One common reason for a noisy hot and cold water tank is a malfunctioning pressure reducing valve. The valve is responsible for releasing excess steam to ensure safety. When this component faces issues, it results in increased pressure in the tank and prevents steam from escaping, causing strange noises and posing a danger to users.

2. Handling Noisy Hot and Cold Water Tanks
2.1. Regularly Clean the Hot and Cold Water Tank
The best solution to fix a noisy hot and cold water tank is for users to routinely clean the equipment to eliminate long-term accumulated dirt. Follow these steps for cleaning the tank: First, turn off the power and water supply to the machine for a few hours to prevent burns from hot water during the process. Then, connect the water pipe to the drainage pipe at the bottom of the tank and the remaining end to the water drain, and open the drain valve. You will observe discolored water with dirt and sediment flowing out; proceed to drain all the water from the tank.

2.2. Replace the Pressure Reducing Valve
If the pressure reducing valve malfunctions, the only solution is to replace it with a new one. Note that before replacement, ensure the power is cut off or contact a repair technician for assistance

2.3. Use a Water Filtration System
For households in areas with polluted water sources and high impurities, it is advisable to use a primary water filtration system or a water filter. This helps ensure that the water supplied to the hot and cold water tank is clean and reduces the occurrence of noisy hot and cold water tanks.
