Notice if there are minor signs of leakage as a major leak usually follows. The best option is to monitor the water heater constantly. Keep it out of rust, strange noises, and leaks. So, this is just an overview, so you better read further!


Reasons Why Hot Water Heater Is Leaking

A leaking water heater is due to issues you or a professional must fix.


#1. Drain valve

The water heater leaks because of a drain valve. Solve the issue as you tighten the connections using a wrench. Then, replace the faulty drain valve as you remove the old drain valve. After that, wrap the threads in the plumber’s tape and install a new one. Drain the tank in a water heater first before you do this job.


#2. Inlet and the outlet

The source of a leak in a water heater is the inlet and outlet that connects to the pipes. Check the connections between them. Any loose-fitting material requires you to tighten it using a pipe wrench.


#3. T&P Valve

A leak in the relief valve is another cause why the hot water leaks. See for any possible leak after you check the T&P valve. Replace the T&P valve in the drain valve. Hire a licensed plumber if you think the component is critical in its safety. Replace its valve after you notice a leak in the area.


#4. Anode rod

The heater does not rust easily, but the anode rod does attract corrosive materials. But then, the water heater leaks because of anode rod corrosion, as this occurs as water leaks through the space where you find the anode rod.


#5. Sediment buildup

The sediment accumulates underneath the water heater tank. The regular draining in the tank avoids this problem. Drain the tank as always, or else sediment will build up, resulting in cracking, as this requires replacement in the water heater. Drain the water heater to avoid any unnecessary damage caused by deposition.


#6. Cracked internal tank for storage

Your water heater may be following or past the life expectancy it has. That is why the internal tank deteriorates and causes a leak. This leak is visible in the pooling of water right below the unit. The leak can come anywhere in the tank. This internal leak is not easily detected outside of the tank. Thus, an old water heater requires proactive replacement. Utilize a high-efficiency and new model like a hybrid heat pump water heater.


Steps To Fix A Water Heater Leaking

Follow the steps below to fix a water heater leaking.


Step #1. Turning the water off

Do not contact an expert right away if the water heater is leaking. Turn the water off immediately, avoiding leaking. Look for the shut-off valve through the cold inlet pipe in a water heater tank. A gate-style valve requires you to turn it clockwise, while a ball-style valve requires you to turn its handle 180-degrees. Moreover, a broken valve requires you to turn off the water at home that turns off the water supply.


Step #2. Turning off the power

Turn off the water heater’s power, too. Shut off the power in an electric water heater in the breaker, this is before you begin to work with the tank. Shut off the gas in the gas water heater’s gas line. Consult an expert if you cannot cut off the supply of power.


Step #3. Determining the origin of the leak

Determine the location and the cause of the leak in your water heater. The leak can come from the bottom or top of the device. The areas to scrutinize include cracked internal tank, anode rod, T&P valve, inlet and outlet, and drain valve. You may also want to read about how long does a hot water heater last.
