A leaking boiler is a problem that should never be ignored. Even a small drip can lead to water damage, higher bills, and more serious breakdowns if left unresolved. If you have noticed your boiler leaking in Walthamstow, Woodford, or Leytonstone, it is important to find the cause quickly and call a qualified gas or heating engineer to put it right.
Common Reasons for a Leaking Boiler
There are several possible reasons your boiler may start leaking. While some issues are relatively minor, others can point to more serious faults.
Faulty Internal Components
Leaks often occur when internal parts such as the pump seal, pressure valve, or heat exchanger become damaged. Over time, these components wear out and may need replacing. A professional boiler repair in Walthamstow or Woodford can quickly identify and fix faulty parts.
Corrosion and Wear
As boilers age, corrosion can develop inside the system and weaken seals or joints. This is one of the most common causes of leaks in older boilers and often signals that a replacement may be more cost effective in the long term. If you find yourself needing frequent boiler repairs in Leytonstone or Walthamstow, it may be worth considering a new boiler installation.
High Pressure
If the boiler pressure is set too high, excess water can escape from the pressure relief valve, causing a noticeable drip. Checking your pressure gauge and keeping it at the correct level is essential. If pressure keeps rising unexpectedly, you should arrange boiler servicing in Walthamstow or Leytonstone to prevent further damage.
Loose or Damaged Pipework
Vibrations or poor installation can cause joints and connections in the pipework to loosen over time. Even small leaks from pipe fittings can lead to larger issues if ignored. A heating engineer in Walthamstow or Leytonstone can reseal or replace faulty pipework to restore the system.
Poor Installation
If a boiler was not fitted correctly, leaks can appear much sooner than expected. This is why choosing an experienced installer is so important. A professional boiler installation in Woodford or Walthamstow ensures your system is set up safely and securely from the start.
What to Do If Your Boiler is Leaking
If you notice water coming from your boiler:
- Turn off the water supply to reduce the risk of further leaks
- Switch off the heating system for safety
- Call a qualified gas engineer in Walthamstow or a heating engineer in Leytonstone or Woodford to inspect the issue
Do not attempt to dismantle the boiler yourself, as this can be dangerous and may invalidate your warranty.
