Deal with a Leaking Hot Water System in 4 Easy Steps

For most of us, the way our hot water systems work is pretty simple: you get under the shower after a long day, you revel in the steaming hot water, and you get on with the rest of your evening. It's not until there is a problem like a leaking hot water system that it even gets a second thought.

It's important to understand a little more about this very important part of your household plumbing and everyday life. For a start, make sure that every six months or so, you check and operate the relief valve. Another occasional plumbing maintenance check is to visibly check out your hot water system because something alarming might be starting to occur: Is your hot water system leaking?

But before we get to what to do about that leaking hot water system, let's explore a few things that might have gone wrong:

Why is my hot water leaking?

Hot water tank leaking. While a damaged or corroded storage tank is a fairly common cause of a hot water leak, unfortunately, it will probably require a new hot water system replacement. Most often an electric hot water tank is leaking from the top where the hot water anode is installed.

Leaking pressure relief valve. The reason you should operate this valve every six months is because they, as expected, relieve pressure. If you see hot water leaking from the valve itself, you can probably just get it replaced.

High water pressure. If the pressure in your hot water system becomes too high, it can lead to a leak. This is often due to a faulty pressure relief valve, which is designed to release water when the pressure or temperature inside the tank gets too high.

Leaking pipes and fittings. You'll notice a lot of pipes and fittings connected to your hot water system and home, and they sometimes become loose or wear. Most often the leak is at connections such as the inlet or outlet to the hot water unit. A top rated local plumber should be able to fix this sort of hot water leak for you.

So now that you have a basic understanding about what the hot water problem might be, it's time to think about what you should do if you notice your hot water system leaking.
