If you discover that your water heater is leaking, you must act immediately. A leaking water heater may seem like a minor inconvenience, but in reality it can quickly become a major problem. The average water heater has a 50 gallon tank and when water leaves the tank (drained or leaking), cold water quickly fills it to capacity. As the tank keeps filling up due to the water heater leaking, the area around your tank will become flooded. Even a small amount of water leaking from your water heater can damage your floors, sub-floors and walls. A major flood could result in high repair bills and damage to personal property. Leaks in the water heater can also pose a health problem and lead to mold. A water heater leak will not go away on its own. It gets worse over time.Not all hot water leaks are serious. Some can be fixed by simply tightening a connection. Others might need a little more attention, but you can probably do the repairs yourself, especially if you like DIY projects.Unfortunately, there are also times when your water tank is leaking and you need to either call a plumber to fix it or buy a new water heater.In any case, this article will help you figure out why your water heater is leaking and what you need to do to fix the problem.Let us begin!
What to Do First: Water Heater Leaking
If your water heater’s leak isn’t obvious, it’s a good idea to do a little troubleshooting before turning off the water supply. Just because there is water under your water heater doesn’t mean your water heater is leaking.Oven drain lines, water softener drain lines, condensation, and other plumbing items could be the source. These things can easily make your water tank look like it’s leaking, when the problem isn’t your water heater at all.If you cannot see where the water is coming from, you can pat the area dry and place paper towels or newspaper on it. Come back in the next few days. If the water is coming back and you still can’t identify the source, chances are your water heater is leaking.Switch Off the Water Supply

Some manufacturers even label them with red and blue collars or paint.The cold pipe is the water supply line. It allows cold water to enter your water heater when hot water is drawn off. Follow the line and look for a shut off valve. Most water heaters have a shut-off valve on the water supply line.How to turn off the water
There are two types of valves commonly used:- Ball Valve – Ball valves have a lever handle. Pull or twist the handle down to turn off the water supply.
