Why do Radiator Leaks Happen?

If you are a home owner with a water fed central heating system, then you probably already know that radiator leaks can be common. In fact, radiator leaks are the most frequent type of tracing water leaks to occur in domestic plumbing. This is especially true of older heating systems. So why do radiator leaks happen so often?

To answer this question we need to talk about fatigue. Have you ever noticed how bending a piece of metal back and forth makes it weaker, and ultimately easier to break? Well exactly the same thing goes on in the pipes and fittings of your heating system every day.

As pipes and fittings heat up, they expand. As they cool down they contract. This constant cycle of expansion and contraction causes fatigue, and in the same way that bending a piece of metal backwards and forward weakens it. This constant cycle weakens your pipes and your fittings.

Eventually, part of the heating system begins to gas leak, and this is almost always one of the fittings which attaches to the radiator, as these heat up the most, therefore expanding and contracting more. So there you have it, an explanation of how radiator leaks are caused. Now you know why they happen, call ADI on 08007313843 to have them fixed!
