When it comes to hot water leaks, even a tiny drip can quickly become a gushing problem.

If you're reading this article, you've probably just suffered through a colder than usual shower and checked your hot water system, only to find a puddle underneath the tank – a leak!

If you've ever asked yourself, "Why is my hot water system leaking?" then you’ve come to the right place. Within this article, CDL plumbing will outline what to do if your hot water system is leaking, who to call, the causes of a leak, and the importance of getting it fixed quickly – to avoid finding yourself in more hot water.

How to Deal with Your Hot Water System Leaking

Before diving into what to do after noticing your hot water system leaking, let's go over what makes up the hot water system and where your leak will most likely originate. The main components of the hot water system that you need to be aware of are the tank, the pressure relief valve, the top cap, and the connected pipes. Understanding these vital components will help you to understand how the leak may have occurred. Most hot water systems come with a manufacturer warranty of up to 10 years, depending on the brand.

Step One: Locate Where the Leak Is Coming From

The identification process begins by completing a thorough inspection of your hot water tank. Check if the hot water system is leaking from the top cap or the bottom.

Typically, it is a more straightforward fix if the leak is coming from the top cap, than the bottom. A leak on the bottom indicates a problem with the tank itself. Other locations for the leak may be the release valve, or from nearby pipes, which is an entirely different problem.


Hot Water System Leaking from Release Valve


A leaky release valve is not the end of the world. Sometimes these parts of a hot water tank leak a small amount of water; however, if it is a constant leak, that is cause for concern. A release valve replacement is usually an inexpensive replacement and, when mended early, can prolong the life of your hot water system, while lowering your water wastage.


Hot Water System Leaking from Top Cap


The most common reason your hot water system may leak from the top cap is due to an issue with loose connecting pipes. Top cap leaks tend to be a much easier fix than any issue involving other parts of the hot water system.


Hot Water System Leaking at Bottom


A hot water system leaking from the bottom may result from a drain valve at the bottom of the unit that is faulty. A plumber can easily replace these valves. It is crucial to ascertain whether the leak is coming from the bottom of the tank and not trickling down the tank from a leak at the top.

Step Two: Turn Off the Water

Once you have determined the leak's location and the severity of the leak, turn off your water supply. Turning off the water supply is either done directly at the hot water system or via the water supply for your entire home. This may sound like a major inconvenience but stopping water from entering the system is essential to lowering the potential for damage to your system or home and will save you time and money down the line. This step applies to all hot water systems, whether electric, solar, or gas.

• If heated water is leaking out of the tank, this is a massive waste of power and electricity and will increase your bills.
