Here’s how to prevent and fix radiator leaks to keep your home warm and efficient.

Common Causes of a Leaky Radiator

1. Corrosion — Rust and corrosion create small holes where water escapes.
2. Loose Joints — Poorly tightened connections between components cause drips.
3. Faulty Valves — Worn or damaged valves are a frequent cause of radiator leaks.
4. Pressure Problems — Excessive boiler pressure can strain radiators and cause leaks.

How to Prevent Radiator Leaks

• Inspect Regularly — Check for early signs of corrosion, damp patches, or loose joints.
• Bleed Radiators — Remove trapped air to reduce system pressure and improve efficiency.
• Use Corrosion Inhibitors — Add chemicals to your system to reduce rust risks.
• Schedule Professional Servicing — Book annual heating maintenance with DAKS Plumbing.

How to Fix a Leaky Radiator

1. Turn Off Your Heating — Ensure the system is off and the radiator cool before inspecting.
2. Locate the Leak — Check around valves, joints, or corroded spots.
3. Tighten Fittings — Carefully tighten connections without over-tightening.
4. Seal Small Leaks — Leak sealants provide temporary fixes, but professional repair is best.
5. Replace Damaged Parts — If parts are beyond repair, call an emergency plumber.
