Why Is My Boiler Leaking?

Why Is My Boiler Leaking?



Your boiler can serve you reliably and effectively for many years. Boilers have an average lifespan of 20 years. However, like every other home system, they may experience problems such as leakages. Water leaking boilers require the attention of an experienced technician since they could lead to damages. We recommend regular boiler maintenance in the Greater Toronto Area by our technicians at A-Plus Quality Heating and Cooling to prevent such issues. Below are some of the common causes of leaks in boilers and what to do.

Possible Causes of Boiler Leaks

There are many reasons for leaking boilers, but we will discuss a few of the most common causes. They include the following:

Corrosion

When dirt and debris buildup inside your boiler, it encourages corrosion of pipes and radiators. Over time corrosion weakens your tanks and pipework, which eventually leads to water leaks. If rust and corrosion have not spread further than a valve or a single pipe, then replacing the part can resolve the issue. However, if it has spread across the boiler, you will need to replace the whole system.


Pressure

High pressure is the most common cause of leaks in boilers. Boilers come with an outlet pipe that lets out excess pressure and prevents the system from imploding. The recommended pressure is between 1 and 2. If you notice the pressure gauge reads more than that, you need to reduce it.


Temperature

All boilers come with a temperature control valve (TCV) that monitors the water temperatures. The TCV regulates the water temperatures from getting too high. If you notice leaks from the TCV, it’s a sign that the temperatures are too high.


Pump seals

Due to contraction and expansion over time, your boiler pump can develop cracks that cause water leakages. The pump requires either resealing or replacement.


Loose Joints

Your boiler expands and contracts as temperature changes from cold to hot. This change can affect the joints and cause leaks. Through boiler maintenance in the Greater Toronto Area, the joints such as all pipes and tubes connected to the body can get tightened.


Wear and Tear

Like everything else, boilers do not last forever. If your boiler is old, it could experience leakages, and you need to replace it. It also consumes a lot of energy that leads to high monthly bills. A new system will not only save you money but will also offer you efficient heating.


What to Do if a Boiler is Leaking

The cause of leaking boilers can either be simple or complex. Nevertheless, they require immediate inspections from a certified technician from A-Plus Quality HVAC services in the Greater Toronto Area. While you should not attempt to perform repairs on your own, there are a few steps you can take to protect your home.

•  Turn off your homes water supply 

•  Switch off the boiler

•  Wipe any leaked water

•  Finally, contact a qualified technician for boiler repair in the Greater Toronto Area from A-Plus Quality Heating and Cooling.

Client Testimonials

  • First experience was on New Year's Day, 2020, when furnace stopped. Called A-Plus and they had a rep (Jack) out quickly. He did some troubleshooting. He wasn't giving BS. Gave me options on repairing or replacing. Non-biased, no pressure. I chose replace and it was done the next day. Good experience all around. Second experience was early March, 2021 when a harsh chemical smell emanating from the furnace room, and pushed through the HVAC venting, permeated the house. Very concerning. Was late night, called A-Plus, immediately answered and suggested some safety moves for the evening. Booked a visit for the morning. Jack again came and assessed the issue and advised where the smell came from (outside). Again, very professional, quick, no BS, good guy. Completely satisfied with the service after often being given the BS treatment from other service providers for the house. Would definitely recommend.

FAQ

  • Water is Leaking on my Furnace

    Water falling on to the furnace can harm your heating unit by affecting the control boards and other components enclosed in the furnace. There can be many causes to the water overflow, but the most common cases in the summer is the ice build up inside the evaporator coil due to low refrigerant level. Water build up can also be due to the evaporator coil having a crack on the base, if this is the case contact us by booking an appointment or call us today to have a technician come have a look at your unit and repair this issue before it causes excessive damage.  

  • Most common Boiler Issues

    - Boiler fails to ignite
    - Low pressure
    - Strange Noises
    - Boiler is not responding to the thermostat
    - Cold Radiators
    - Boiler leaking or dripping
    - Boiler cycling very fast

  • Why is there ice building up on the copper pipes?

    There can be many reasons why the refrigerant pipes are freezing up but the most common issue is low refrigerant levels. If your AC unit has ice buildup turn off the unit for at least 4 hours and call us at 416-410-0337

  • What is a mini-split?

    By definition, and simply put, a “Split System” is a heating and air conditioning system which has two main components, the indoor unit and outdoor unit. In short, the indoor unit absorbs heat energy in the cooling mode, and the outdoor unit rejects the very heat absorbed by the indoor unit. And the cycle is repeated until the set temperature is met. Although the indoor and outdoor units are located in physically different, hence “split” locations, they are connected and operate as, one system; continuously circulating refrigerant liquid and vapor by means of interconnecting, dehydrated copper refrigerant lines, commonly referred to as a “Line Set”.

  • How do I know what size unit I need?
    If you have any problems with your system, you should contact the contractor who installed the units. All our systems are covered by a 5 year parts, 7 year compressor limited warranty
