Why Is My Boiler Leaking?

Thanks to the creation of boilers, the days of boiling water manually are over. If this is your chosen device for heating water, you already know the endless benefits boilers carry. However, just like any other plumbing device, boilers are vulnerable to breakdowns and malfunctions. One of those common problems is a leaking boiler.

If you would like to learn about the main reasons for your boiler leaking, keep reading to hear from our Calgary plumbers. We’ve compiled a list of reasons and fixes to help get your boiler back up and running!

Reasons for a Leaking Boiler

Are you wondering why your boiler is leaking? There are a few common reasons for this issue that you can promptly address. Whether from broken boiler seals, loose joint fittings, corroded pipes, extra pressure, or any other underlying issues, there are many permanent solutions for leaky boiler systems, such as our reliable boiler repair services.

Boiler Leaking Because of a Broken Pressure Relief Valve

One of the most common causes of a leaking boiler is a broken pressure relief valve. All boiler models are built with a pressure outlet pipe to release excess pressure in the unit, ensuring no water leaks out.

Pressure pipes are usually built without sealed fittings to ensure excess pressure can escape the system. However, this can result in some water drips. If you have a small amount of water coming out of your pressure pipe, then this may just be the unit doing its job.

However, if you're seeing more than a couple of drops come out of the pressure pipe, then you may be dealing with a malfunctioning boiler pressure relief valve that is causing excessive pressure to build up within the unit.

To see if your unit is experiencing pressure issues, check the boiler pressure gauge valve needle to see if it's pointing green or red. If it's red, you'll need to call in our qualified professional plumber to bleed the boiler to lower its pressure back to a normal level.

Boiler Leaking Because of Loose Joint Fittings

Another reason you may have a leaking boiler is loose pipe joints. Boilers deal with extreme temperature changes, and in order to do so safely, the pipes need to be properly installed with pipe fittings. When your boiler is leaking, it may be because of loose joints in the pipe system.

If you're unsure if this is the issue, inspect the boiler pipework, including the visible pipe fittings, tubes, and pipes that are connected to the boiler. Wipe the wet area dry and wait until water appears again. If the pipes or fittings appear to leak, then you will need to contact our experienced professionals. Our plumbers have years of experience tightening loose joint fittings and repairing broken pipes.

Boiler Leaking Because of Corroded Boiler and Broken Seals

Since boilers are constantly exposed to water, your boiler tank may suffer from corrosion over time, causing water leaks. If you suspect that your boiler is experiencing corrosion issues, it's best to get a professional inspection to see if it's time for a water tank replacement. In some cases, your boiler may not be corroded but instead built up with mineral deposits. If that is the situation, we can clean any excess sediment from your unit.

Boilers naturally contract and expand due to extreme temperature and pressure changes. This can also cause potential issues, such as broken rubber seals around the boiler unit. When you have broken seals, your property is susceptible to water damage since a pool of water will sit outside the boiler unit. To address this boiler leakage issue, you can schedule boiler repair with our team of trusted plumbers.

Boiler Leaking Because of Faulty Heat Exchangers

Another common cause of boiler water leaks is a broken heat exchanger. The most crucial component of your boiler, this takes cold water and converts it to hot water. Boiler heating elements can corrode or crack over time, causing a pool of water to build up in the boiler's bottom. Cracked heat exchangers also pose a health risk to homeowners. That's because these heat exchangers use various deadly gases to convert cold water to hot water.

If you are concerned that you may have a faulty heat exchanger, then contact our team promptly for emergency service. Our boiler experts recommend getting an inspection to see if the heat exchanger is cracked or broken. If that's the case, it's more cost-effective to get a boiler replacement because it is the most costly boiler component to replace.
