Water Heater Leaking from Bottom

Corrosion is the most common reason that reduces water heaters’ lifespan and makes them leak. The factory-installed magnesium anode only protects your tank temporarily and needs frequent replacement to stay efficient.

If your actual water heater is leaking from the bottom, it is time for a new one and you should protect it properly with Corro-Protec. Our system provides a permanent layer of corrosion protection on the internal welds and weak points of the tank.

Water heaters have a limited lifespan, regardless of quality regulations for manufacturers. The vitrification process to protect the inside of the tank is often imperfect (or perfect for planned obsolescence) and magnesium anodes only last a few months or years before corrosion sets in.

If you change your original magnesium anode every few months or years, your water heater will last many years. However, nobody wants to go into a crawled space every year to work on their hot water tank.

That’s why we created Corro-Protec: our first-class anode combined with electrical current to provide optimal corrosion protection and double the life of your hot water tank.

What causes my water heater tank to leak?

Leaks in a water heater can be caused by corrosion of the tank. This is often due to the presence of magnesium anodes, which can corrode away and leave the tank vulnerable to leaks.

The water heater heats water in a closed and pressurized tank. This is the PERFECT mix for corrosion to take place and create an internal tank leak. Add a water treatment system to the equation and voilà, corrosion is happening faster than ever.

New manufacturing methods for water heaters were supposed to add years of service life by reducing corrosion, but it looks like these attempts are more about marketing than really changing the industry. Vitrification and sacrificial anode rod are both ways now used to try to reduce the corrosion inside your tank.

If you have a water heater that is leaking from the bottom of the tank, it is likely time to replace it. Water heaters also have a limited lifespan, and it is often necessary to replace them after a certain amount of time, especially when not protected adequately.

How could I prevent corrosion in my tank?

No matter what causes the corrosion in your water heater, the Corro-Protec Powered Anode Rod can stop this process in just a few hours.

Once the system is operational, the energy projected by the system will prevent corrosion for years to come! Your water heater will be protected and you won’t have to worry about this again. Please note that if your tank is leaking, you should install a powered anode rod as soon as you install your new tank.


What protection does my tank have?

Sacrificial anodes

First, sacrificial anodes – magnesium, aluminum, and zinc – are used to protect water heaters, but only last a few months in hard water and need to be replaced when 60% corroded.

To make sure this type of anode is working efficiently, you always need a proper one in place, otherwise, your water heater will be unprotected. If your tank is unprotected, corrosion will appear over time, then leak if the corrosion process is sufficiently advanced.


Second, vitrification is a process that manufacturers claim will extend the life of tanks. However, this process has been on the market for over 10 years and does not seem to be effective, due to defects during manufacturing, shaking when transported, and improper handling during installation.

Moreover, if you do not drain the limescale deposit regularly, the build-up sediment will cause cracking on this defense and the steel tank. As expected, when both defenses are down, corrosion will take place which will become substantial and be followed by leaks.

How to prevent my water heater from leaking?

To avoid leaks, prevent corrosion first.

Corro-Protec systems employ current to stifle corrosion in your water heater. This tiny bit of electricity going into your water heater will protect it for 20 years or more.

Corro-Protec is the most effective and powerful way to stop corrosion without requiring any maintenance or monitoring, thanks to our powered anode rod. With less than $2 worth of power per year to operate, Corro-Protec is the most cost-effective method of preserving your investment in the long run and preventing water damage.

«I retired from a utility company in the department,so I know about anodes and rectifier fields.This thing worked great for the rotten egg odor in about 2.5 days odor was completely gone. easy to install. I would highly commend it.»

James Hendrickson

«This product is amazing! After bleach treatments in my water heater every 3-4 weeks, even with an aluminum /zinc anode rod. It is quite easy to install. Within 3 hours the sulfur odor was significantly reduced, and with 16 hours it was eliminated. If there are any significant changes, I will surely provide an update.»
