Why is My Water Heater Leaking? Your Guide to the Typical Causes of a Busted Water Heater

Nobody enjoys wondering “why is my water heater leaking” while standing ankle-deep in chilly water in their basement. Or sitting on the couch and noticing water dripping from the ceiling onto their head. The last thing you want is for a broken water heater to ruin your carpet, pictures, comic books, or other priceless items with water. In order to help you prevent the terrible flooded basement disaster caused by a water heater rupture, we’ve put together this guide with our top reasons for a water heater leaking. Continue reading to learn how to fix the most typical causes of leaking or broken boiler.


Sediment & Rust Buildup in the Water Heater

Steel makes up the majority of water heaters. Since iron rusts, steel, which is primarily made of iron, corrodes. Anode rods, which are a protective measure for water heaters against rust, may eventually wear out or break, allowing your water heater to leak from the top anode. We advise calling a plumber to replace the anode rod in your water heater if you find that the hot water coming from your faucet is an unpleasant, rusty brown hue.

In addition, the majority of homeowners use hard water in their water heaters. Small amounts of minerals that are dissolved in hard water will eventually start to collect in the bottom of your water heater’s tank. As a result, a layer of buildup formed that prevents water from getting to the burner.

Why does this matter? It results in slower water heating, which increases the risk of overheating, general wear and tear, and—most frequently—leaks from the base of your water heater. The good news is that you can prevent this issue by draining the water and flushing away any accumulated sediment at least once a year. If not, you can run into some of the issues with the water tank listed below.

Air Pressure

When the temperature is too high or the pressure of the outside water entering your home is too intense, excess air pressure rises inside the tank of your water heater. Make sure your water heater is set no higher than 120–125 degrees to avoid these issues.

Additionally, we advise monitoring the temperature and pressure relief valve on your water heater (also known as a t&p valve). When necessary, it relieves pressure from the heater’s tank, which is on the top or side of your tank. We advise replacing the valve right away if you test it and no water leaks out, or if the t&p valve is the source of the leak. If at all possible, avoid replacing it with a plastic valve because they are cheap and prone to breaking again quickly.

Internal Tank Leak

An internal tank leak may be the most frequent cause of your water heater dripping water from the bottom. This can be a sign that the reason your water tank is leaking is because of interior tank damage brought on by a structural flaw. If sediment hasn’t been removed from your tank for a while, corrosion may have developed, leading to a fracture in the tank shell or another problem. Check your tank’s exterior for any indications of major interior problems. The only option here will most likely be to replace your water heater.

Leaking Drain Valve

If you discover that your water heater is primarily leaking from the bottom, a leaky drain valve may be to blame. You can have a flooded basement if the drain valve malfunctions. As previously discussed, drain valves are used to drain the hot water from the tank and remove the sediment. You may only need to tighten the valve a little bit to fix your water heater leak. To avoid breaking the valve and worsening the leak, avoid overtightening. Simply locate the handle or knob and make sure it is properly tightened, but first make sure the leak is coming from the drain valve and not from somewhere else.


Last but not least, aging may be the cause of your water heater’s demise. The average lifespan of a hot water heater is 8 to 10 years. Due to normal wear and tear, simple leaks are more likely to occur at the end of their life cycle. These potential leaks may also be caused by corrosion, years of sediment damage, and the inevitable harm of aging.
