Water heaters are essential to any household, providing hot water for daily activities such as showering and washing dishes. However, they can also be a source of headaches if not maintained properly.
One potential issue that homeowners may face is a leaking water heater. This problem causes inconvenience and can lead to serious damage to your home if left unattended.
In this guide, we will discuss how to know if water heater is leaking and what steps you can take to address the issue. So whether you have a traditional tank water heater or a newer tankless model, read on to learn how to spot a leak and what to do next.
Understanding Water Heater Components
Before we dive into how to detect a leak, it is important to have a basic understanding of the different components of a water heater. This will help you identify where the leak may be coming from and determine the best course of action.
- Storage Tank – Traditional water heaters have a large storage tank where water is heated and stored until needed.
- Pressure Relief Valve – This valve is designed to release excess pressure from the water heater, preventing it from exploding.
- Drain Valve – Located near the bottom of the water heater, this valve drains and flushes out sediment buildup.
- Inlet/Outlet Pipes – These pipes allow cold water to enter the tank and hot water to exit towards your home’s fixtures.
In addition to these components, there may also be a temperature and pressure relief valve, an anode rod, and a heating element, depending on your water heater. Familiarizing yourself with these parts will make it easier to identify potential leaks.
