Boiler being repaired
February 12, 2021

Whether it’s a slow drip or a gushing stream—nobody wants to see water leaking out of their boiler. But unfortunately, boiler leaks happen, especially when boiler maintenance is neglected. If your boiler is leaking, it’s important to prevent further damage by turning off its water and power supply. Then, you should call a trusted HVAC contractor to address the problem. 

But while you’re waiting for your heating and cooling contractor to arrive, you’ll probably find yourself wondering what’s causing the problem in the first place. To shed light on this panic-inducing problem, we’ve rounded up some of the most common reasons why your boiler could be leaking, and how to solve them. 

The Problem: Corrosion 

Your boiler is made of metal, and it’s full of water —the two essential ingredients for corrosion. As boilers age, their tanks and pipes can corrode, weakening the metal and causing it to deteriorate. When this happens, water can easily escape. 

The Fix 

If the corrosion is contained to a single pipe or valve, replacing the affected part is likely enough to solve the problem. But if the entire tank has begun to corrode, it may be time to have a new boiler installed. 

The Problem: High Pressure 

Your boiler needs to maintain a certain pressure in order to operate safely (usually between 12 and 18 on the pressure gauge). If it gets to be too high, the valves will allow water to leak out in order to relieve the pressure and prevent the tank from rupturing. This is often the result of sediment accumulating around the pressure valve. 

The Fix: 

Solving a boiler pressure issue may be as simple as clearing away the sediment that’s blocking the valve, or replacing the blocked valve. However, when not addressed correctly, pressure issues can cause your boiler to implode, so it’s best to enlist the help of an experienced HVAC technician when dealing with this type of problem. 

The Problem: Damaged Seals 

Your boiler pump pushes hot water through your heating system, and without proper sealing, some of that water is bound to leak out. Seals can lose their effectiveness over time, either by becoming loose or corroding. 

The Fix  

Luckily, damaged seals can be easily replaced and an HVAC contractor will be able to help you with this problem. 

The Problem: Faulty Temperature Valves 

Your boiler doesn’t just need to maintain a certain pressure, it also needs to maintain a certain temperature in order to operate safely and effectively. When temperatures get too high, pressure rises, forcing the unit to leak. 

The Fix 

Your boiler is equipped with a temperature probe that regulates the temperature inside the boiler. If your boiler is overheating, you may need to repair or replace the temperature probe. 

The Problem: Poor Installation 

Oftentimes, a leaky boiler system comes down to a poor installation. Whether the contractor that installed your boiler was inexperienced or just didn’t do a great job, you’re likely to run into issues like leaky pipe fittings.  

The Fix: 

A reputable contractor can assess the damage and let you know whether it can be repaired or if entire parts will need to be replaced. Remedying a poor installation can be expensive, which is why it’s so important to partner with a contractor that you trust for major HVAC projects, like boiler installation.
