Water heaters make your lives comfortable. A leisurely warm bath at the end of the day is the best stress reliever, including soothing those aching muscles. However, sometimes, as with almost all plumbing fixtures, they can develop a leak or two. Initially, it is terrifying and then frustrating. Knowing the source of the problem will help the professional take care of it quickly since you will learn about it beforehand.

Reasons Behind Leaks in Your Water Heater

If you have had a heater leaking lately and thinking of searching for a “plumber near me” on the internet, try to know the reasons with the information below.

Excessive Pressure

How that happens is like this. Some pressure is automatically created inside because the heating system expands when it heats the water. The more the water temperature, the greater the tension built. Too much pressure inside the water tank leads to leaks from pre-existing cracks and other loose fittings. Leaks occur when water enters the system at high pressure. Faulty pressure relief valves also cause an excessive buildup of pressure. Most water tanks are steel lined with glass or porcelain enamel, containing anodes (magnesium or aluminum rods). If the rods are of poor quality, they can cause the tank to explode, along with the high pressure already created.

Faulty Drain Valve

A drain valve in the water heater is used to release water and remove contaminants. With time, mineral scale is formed inside them, along with sediments like sand and dirt. These reduce the heating efficiency of the heater as a whole. It is essential to get it checked in time before there’s permanent damage. The way to do this is to open the valve at occasional intervals and allow the contaminants to escape. However, sometimes the valve can get loose, which results in leakage. Leakage from the base indicates that it isn’t watertight and might need to be replaced by a plumber.

Corrosion of the Water Tank

The point mentioned above is related to this one. Sediments will build up in the tank over time. The older the heater, the greater the collection of deposits. The process itself is unavoidable, as water heating leads to the formation of minerals like magnesium and calcium, which settle at the bottom in the form of sediment particles. These have two harmful effects. They form insulation between the heat source and the water, resulting in lower heating efficiency. Second, it leads to corrosion and then leakage. If that happens, the plumber will suggest you get a new water heater.

Old Water Tank

With regular maintenance, a water heater can be expected to last about eight to twelve years. After that, it will exhibit signs of giving out. Some of these are a rumbling noise, weird smell, dirty water, fluctuation in temperature, and less hot water. Other factors that influence its life expectancy are the water’s quality and frequency of usage. Corrosion inside the tank is the final sign that it needs to be replaced. You can use this information to determine the source of the leak before deciding to search for “plumber near me” on the internet. However, it would be best to leave it to them to do any replacement or maintenance work as they are professionals and possess the required expertise.

    Remember, hot water rises to the top of your hot water heater’s tank. It’s here that the hot water is replaced by cold water, which then migrates to the bottom of the tank to be heated. Your water heater knows when to heat water thanks to a signal sent by the system’s thermostat, calling for the burner to be switched on.
