Water Heater Repair: 3 Causes of Water Heater Bursting

Any appliance that uses electricity or gas can burst. The same is true for water heaters. It is a reality that we need to remember. Most new smart appliances have the necessary technology to safeguard against unwanted situations. That said, it is extremely helpful to know why water heaters usually burst so that you can check once in a while to make sure everything is alright. If you notice any of these problems or anything related to it, you should contact a professional water heater repair company.

Since a water heater is an important appliance, you should regularly maintain it. Maintaining it means cleaning the sediment, checking and replacing parts & fixtures, checking the pipes for leaks, ensuring the safety of the electricity, etc.

Top Causes Of Water Heater Bursting

Building Up Of Sediments.

One of the most common reasons for water heaters bursting is the buildup of sediments. Sediments are minerals that are present in hard water. They build up inside your water heater over time and can become really problematic. However, the settlement of sediment is usually at the bottom of your water heater. Over time, this can build up to a point where the mineral insulates the water from the burner, which forces the burner to heat the water for a longer period of time. It can cause overheating, and, in turn, your water heater can burst.

Your water heater will make sounds of fuzzing, pooping, or knocking. Initially, you may also notice some discoloration in your water, or your water has smells of sand. If this happens, you should clean your water heater yourself or call an expert. You can use a vinegar-water solution to clean the water heater. For prevention, you may want to install a water softener or clean the water heater for sediment once a year. If the sediment problem is bad, you can hire an expert for the water heater. They will have non-toxic chemicals that will break up the sediment very easily.

Rusts Or Corrosion Inside The Tank

The tanks of water heaters are prone to rust. This is why tankless water heaters are sometimes the best choice. However, if your water heater’s tanks or any other part is made out of metal, it can develop corrosion as it is in contact with water almost every moment. However, this is the reason water heaters have anode rods. When this anode rod gets destroyed, the corrosion will not allow your water heater to work efficiently.

Moreover, with corrosion in your tank, your heater is prone to bursting. The easiest way to detect corrosion is to look for discoloration in your water. If the water coming out is a bit rusty or brown in color, you have a problem.

To avoid this from happening, check your anode rod every six months. You can do this yourself. If you notice that the anode rod is about to wear out, call a water heater repair expert so that he can replace the anode rod. Water heaters with warranties do not need half-yearly checks. Instead, check them once a year. All of these issues are dealt with in regular maintenance services provided by esteemed water heater repair companies such as EZ Plumbing and Restoration.

Extreme Internal Pressure

The water heater, as the name suggests, heats up the water. Heated water reaches its boiling point and starts to vaporize. It builds up pressure inside the tank that holds water. If the pressure is high enough, it will cause bursting. Every water heater has something called a temperature and pressure relief valve. It keeps the pressure steady and saves your water heater from bursting. But like everything else in your water heater, this can become faulty as well. If there is debris in your water heater, it could mean your T&P valve is malfunctioning. In that case, you can hire an expert water heater professional to detect the problem, and if there is any, the expert will replace or repair it.

However, even with a perfectly working T&P, the water heater can build up too much internal pressure. Set the temperature of your water heater to 120-125° degrees Fahrenheit. It will maintain a very safe internal pressure. Also, check your T & P valve at least twice per year to avoid an unwanted situation.
