Why My Water Heater Is Leaking: 5 Main Causes
Hot water is a necessity in our everyday lives, whether it’s for a relaxing shower or doing the dishes. Therefore, a leak in your water heater can be very annoying. Leaks in water heaters can result in severe damage, increased energy costs, and possible safety risks.
If you discover a leak in your home’s water heater, you should contact water heater repair Saratoga Springs to fix the issue right away because a prolonged leak can have detrimental effects. If you fail to address the leak as soon as possible, the water may eventually damage your walls, floors, and furniture. Finding the cause of your water heater leak is the first step in fixing it.
Here are the leading causes of your water heater leak:
- Loose drain valve
The water heater’s drain valve, located close to the bottom, empties the tank so that maintenance procedures like clearing away sediment can be completed. Regular use or wear and tear may cause the valve to loosen over time. A leaky valve may cause water to leak from the heater’s base. Thankfully, there’s usually a simple solution: tightening the valve could halt the leak. However, the valve can require a complete replacement if it is broken or damaged.
- High pressure
Since the tank in a water heater handles hot water, pressure naturally develops in these units. Steam produced by hot water increases tank pressure, which rises as the water heats. Water leaks through cracks, loose pieces, and other areas could be visible if the pressure within the hot water tank becomes too high. Excessive pressure may result from an overheated water temperature. Furthermore, leaks occur in the tank when the inbound water pressure reaches high levels. An overabundance of pressure can cause the water heater to blow up.
- Sediment buildup
Minerals like calcium and magnesium found in water can gradually collect at the bottom of the water heater tank. The sediment accumulation may lead to overheating in the tank, eroding the metal and finally creating leaks. The sediment accumulation creates an insulating layer between the water and the heating element, increasing the effort required for the unit to heat the water. The additional pressure may lead to corrosion or cracks in the tank. The water heater’s lifespan can be increased and sediment buildup can be avoided by flushing it frequently, once a year on average.
- Cracked or damaged tanks
A more serious reason for water heater leaks is a damaged tank. The age of the tank itself, high pressure, or overheating can cause cracks. Sometimes, the tank may eventually crack due to substandard installation techniques. If damaged, water may seep through the water heater’s inner glass layer, causing leaks. Tank cracks are usually irreversible, and the water heater may need to be replaced. When it comes to older models nearing the end of their useful lives, this is especially common.
- The tank is old
If your water heater has been with you for over 15 years, the age of the tank may be the cause of the leak. Tanks tend to rust with time, and this corrosion creates holes and fissures that let water leak out. You ought to get your tank replaced at that point. An alternative is to switch to a tankless water heater if you have the traditional water heater.
