What Causes Boiler Leaks? Top 5 Reasons Explained
A reliable boiler is the cornerstone of an efficient home heating setup, essential for maintaining warmth and comfort when the temperature drops. Yet, one frequent issue that can disturb this warm balance is the occurrence of water leaking from boiler. Such leaks diminish the system’s performance and pose significant safety and upkeep concerns.
In the following article by Miller Oil Company, we explore the different reasons why boilers leak, illuminate this common problem, and offer guidance on how to resolve and prevent incidents of water escaping from your boiler.

Below, we explore the crucial factors that can lead to boiler water leaks.
Issues with the Boiler Pressure Relief Valve
The pressure relief valve is critical for controlling and venting excess pressure to avoid over-pressurization of the boiler. This valve automatically opens to release water or steam when the internal pressure exceeds safe thresholds, ensuring the pressure stays within a manageable limit.
Various factors can lead to a leaking pressure relief valve, the most typical being excessive pressure accumulation in the system. This issue often stems from a defective expansion tank that fails to accommodate the expansion of water when it heats, leading to increased pressure that forces the valve to release water or steam. Additional causes might include the accumulation of sediment, a faulty valve, or incorrect installation procedures.
Overlooking problems with the pressure relief valve can present serious safety hazards. A valve that malfunctions may result in an unexpected discharge of hot steam or pressure, potentially causing substantial damage to the boiler and its nearby components. Such incidents could lead to burns, damage to property, or even catastrophic boiler explosions. Therefore, it is critical to regularly inspect and maintain the pressure relief valve and address any issues immediately to ensure safe and efficient boiler operation.

Deterioration or Wear in Boiler Piping
Pipes function as vital pathways, distributing water and steam throughout the heating system. They facilitate the transfer of heated water or steam from the boiler to different components, such as radiators or baseboard heaters.
Several elements contribute to pipe corrosion, including the age of the pipes, the quality of water circulating within, and chemical interactions occurring in the system. As pipes age, they are subject to the relentless effects of high temperatures and pressure, leading to rust or scale formation.
Additionally, poor water quality—characterized by high mineral content or acidity—can hasten the corrosion process. Moreover, chemical reactions between the materials of the pipes and any additives in the water can further drive corrosion.
Corrosion in pipes can cause leaks in the boiler system, resulting in water loss and diminished efficiency. As corrosion eats away at the pipes, it compromises their structural integrity, increasing their susceptibility to failure. These leaks waste water and can damage adjacent components and property. Additionally, as corrosion builds up, it narrows the pipes, restricting the flow of water or steam, leading to poorer heat distribution throughout the system.
Issues with Boiler Seals and Gaskets
Seals and gaskets are essential barriers, ensuring a watertight and airtight connection between various boiler components. They are crucial in preventing leaks by keeping water and steam confined within their intended operational areas.
Boiler seal and gasket deterioration often result from regular wear and tear, exposure to extreme temperatures, and interactions with chemicals or minerals in the water.
Such conditions can cause:
- Progressive weakening
- Reduced flexibility
- Increased brittleness
- Heightened risk of failure
- Overall degradation
- Accumulation of deposits
- Accelerated wear and potential failure
Leaking seals and gaskets can significantly degrade a boiler’s performance and energy efficiency. When these critical components fail, they allow water or steam to leak from their designated pathways, resulting in water loss and a drop in system pressure. Consequently, the boiler must exert more effort to maintain the necessary temperature and pressure, leading to increased energy consumption and reduced efficiency. Compromised seals and gaskets may also permit air contaminants to enter the system, further impairing its functionality.

Problems with Boiler Expansion Tanks
The expansion tank in a boiler system regulates pressure fluctuations by accommodating the expansion and contraction of water during heating and cooling cycles. Issues such as a waterlogged tank due to a damaged bladder or diaphragm, malfunctioning air valves, or poor maintenance can lead to significant operational problems.
A waterlogged tank can cause:
- Excessive pressure
- Water leaks
Additionally, incorrect air pressure settings may prevent proper pressure relief throughout the heating cycle, posing safety risks and undermining the boiler’s performance and energy efficiency.
Corrosion in Boiler Heat Exchangers
Within a boiler, the heat exchanger functions by moving heat generated in the combustion chamber to the water, which is then distributed throughout the heating system. Corrosion can occur in the heat exchanger due to poor water quality and the accumulation of minerals over time.
When the heat exchanger corrodes, it may cause water leaks or release dangerous gases such as carbon monoxide into the system. These complications reduce the boiler’s efficiency and present significant health and safety risks.
