Not Sure Why Your Water Heater Is Leaking? How To Identify The Cluprit

If your water heater is leaking, you need to have it repaired as soon as possible. Allowing your water heater to continue leaking could lead to some serious problems including mold growth, wood rot, and even tank rupture. One thing you should know about your water heater is that not all leaks are disastrous, if they're taken care of quickly enough. In fact, some water heater leaks can be fixed quite easily. With some of the easier leaks, you can take care of them yourself with a pair of pliers and some thread-seal tape. Here are four ways to identify the leaky situation your water heater is facing.

Start with the Water Supply Lines

When it comes to identifying a leak on your water heater, you need to start at the top; the top of your tank. You might not realize this, but leaky water supply lines can send water streaming down the sides of your water heater, making it look like you have a bigger problem than you actually do. Take a look at your water supply lines. If you see water coming from around the fasteners, give them a twist. If you can still see water flowing from the lines, you might need to add a fresh strip of thread seal tape. Use a pair of pliers to remove the water supply hoses and wrap a strip of thread seal tape around the threads. Reattach the water supply lines and test for leaks again.

Move to the Pressure and Temperature Relief Valves

The next thing you'll want to check will be the pressure and temperature relief valves. If these are leaking, you might be able to seal off the leaks by using the same thread seal tape that you used to repair the leaky water supply lines. However, you'll need to be careful when you remove the valves, or you could break them, which means they'll need to be replaced by your plumber. Follow the same procedures to remove the valves and replace the thread seal tape. If the leaks stop, you've fixed the problem. If not, you'll need to have your valves replaced.

Now Check the Main Drain Line

If you've recently flushed your water heater, you could have a leak in your main drain line. That can happen when the drain valve doesn't close all the way, or when it's weakened by age. Check the main drain valve, located at the bottom of your water heater. If it's leaking, try to tighten the valve. If it continues to leak, you'll need to have the valve replaced.

It's Time to Call the Plumber

If you've checked everything, and you've still got water leaking from your water heater, it's time to call the plumber. Your tank could be leaking from the base, which means it will need to be replaced. Failing to replace your water heater once it starts leaking from the base could put you at risk for a tank rupture.
