Leaking Boiler

A leaking boiler is not only annoying, it can also be a sign that you will need bigger boiler repair.

Leaking Boiler

While a small puddle of water may not initially look like a big problem, leaks can actually indicate that there is a bigger problem inside your boiler, such as a broken valve or seal inside. When a leak is not fixed right away, it can cause corrosion, rust, short circuits, or boiler explosion. This is actually one of the most common boiler problems homeowners experience, and should be fixed right away by a gas safe registered engineer.

The first step here is to determine the cause of your leaking boiler. Remember that you must never try to do complex repairs yourself unless you are trained and certified.

Here are some of the common causes of a leaking boiler:

  • Boiler pressure – If you see a puddle of water right below you boiler everyday, this can be a sign that there is a need to reduce the pressure inside the tank. Check the pressure gauge to make sure the pressure is set correctly. (more on how to repressurize a boiler)
  • Boiler seals – Damaged boiler seals will allow water to escape, while the boiler pump could be pushing water out of the seals. Check the sides and the bottom of the boiler tank to find out if the seals are broken. If they are, they will need to be replaced.
  • Cracks – As your boiler gets older, the body may eventually develop stress fatigues and damages. Changes in temperature will expand and contract the metal, leading to cracks. Repairing this can be costly. If you have an old boiler, consider getting a boiler replacement for a more efficient model.
  • Joints – Loose connections in the joints can cause leaks, and is an easier situation to fix. Check all the fittings, pipes and tubes as well as the blowdown valve to make sure nothing is loose or damaged.
