Common Causes of a Leaky Radiator
Understanding why your radiator leaks helps prevent future problems. The most common causes of leaky radiator repair in Kent include:
- Corrosion — Over time, rust creates pinhole leaks that worsen if untreated.
- Loose Joints — Connections between pipes and valves can loosen due to vibration.
- Faulty Valves — Worn or damaged valves often cause slow, persistent drips.
- High Pressure — Excess boiler pressure can strain joints and lead to leaks.
How to Prevent Radiator Leaks
Prevention is always cheaper than repair. Follow these leaky radiator repair in Kent tips to keep your system in top condition:
- Inspect Regularly — Look for corrosion, damp spots, or dripping joints.
- Bleed Radiators — Trapped air increases pressure, which can cause leaks.
- Add Corrosion Inhibitors — Protect your system with anti-rust chemicals.
- Book an Annual Service — Regular heating maintenance prevents most radiator issues before they start.
