Are you wondering why your tankless water heater is leaking?

Regardless of why your tankless water heater is leaking, it's always best to address your tankless water heater leaks with the assistance of a Mississauga plumber. Our team at Mr. Rooter Plumbing of Mississauga offers expert tankless water heater repair for your leaky tankless heaters.

Keep on reading to learn more about the common reasons why your tankless water heater is leaking and what to do about it!

Tankless Hot Water Heaters Leaking Due to a Buildup of Mineral Deposits

A common cause of a tankless water heater leaking is because of a buildup of minerals within the unit. While tankless units don't have storage tanks like traditional heaters, they are still prone to high mineral content, which can cause water heater leaks.

When this happens, you can contact our expert plumbers to get your tankless system demineralized. To do this, our plumbing professionals will flush out the water heater system. By descaling the unit, your tankless water heater should operate without any leaks.

To prevent this in the future, we recommend routine cleanings and inspections to ensure the mineral content doesn't build up that much again. You can also get a water softener to alleviate the levels of water hardness in your water pipes.

Tankless Water Heater Leaking as a Result of a Faulty Pressure Relief Valve

The next common reason for a tankless water heater leaking is a faulty pressure valve. If homeowners notice a decrease in water pressure, their tankless unit may have a faulty pressure release valve. When the pressure relief valve fails, excess pressure builds up within the unit without proper venting, causing water leaks to pool around the floor of the unit.

Whenever your tankless water heater is leaking, let our plumbers investigate your pressure valve as a potential culprit. If the issue is because of a faulty valve, our plumber can bleed out the valve to alleviate the buildup of pressure. It is crucial to contact a professional plumber to bleed out the tank, as doing it yourself can result in further safety risks, such as burning. Once you get the system bled out, it's important to regularly seek maintenance for your pressure relief valves in the future to ensure a functional and leak-free water heater.

Tankless Water Heater Leaking Due to Poor Installation

Proper installation is absolutely crucial for a problem-free water heater. If your tankless water heater installation was done incorrectly, your tankless unit will be prone to leakage. When a tankless unit is being installed in your home, internal components must be carefully installed and secured. If these components have not been properly positioned or tightened, then the risk of water leakage increases.

If you suspect that you have had an incorrect installation, you can contact our professional plumbers for a solution to the leaky water heater. We can thoroughly inspect the system, ensuring that all of the wires, pipes, parts, and other components are in their correct position and properly secured in place. This repair process can also help diagnose any other issues, such as poor performance or efficiency, caused by improperly installed components.

Tankless Water Heater Leaking Due to Disconnected Pipe Joints

If your tankless water heater is leaking, it could be a result of loose connections within the water supply lines. Water lines have pipe joints that are connected by pipe fittings to ensure a seamless flow of water. Water leakage around these pipe fittings indicated that they've become loose or disconnected.

If you suspect leaky or disconnected pipes, it's important to address this issue promptly to ensure that your tankless water heater operates efficiently and leak-free. This can also prevent costly water damage repairs. Unnoticed pipe leaks can cause major damage to the structure of your home, which is why you can call our team of expert plumbers to resolve this problem by tightening all of the loose pipe joints and fittings, as well as inspecting the pipes for other signs of corrosion or damage.

Tankless Water Heater Leaking Due to a Corroded Heat Exchanger or Other Broken Internal Heater Components

A tankless water heater leaking and failing to produce hot water could be the cause of a faulty heat exchanger. The critical component in your water heater is the heat exchanger, and if it is malfunctioning it can result in a puddle of water around the floor. Broken components, such as a corroded heat exchanger, will result in a leaky water heater.

When the heat exchanger is extensively damaged, the only option is to replace it. Our team of expert plumbers is able to perform this task for you. That being said, these are costly parts, and you may even decide to replace the unit altogether for a more cost-effective decision in the long term, especially when your tankless water heater is older than ten years. We can help you make an informed decision that will be the best long-term solution for you by taking all of the relevant factors into account.
