What to Do When You Discover a Leaky Radiator

A leaky radiator can be a frustrating discovery, disrupting your home's comfort and potentially causing water damage. However, don't panic! This blog post will equip you with the knowledge to address a leaky radiator effectively. We'll guide you through the steps for identifying the source of the leak, potential DIY solutions and when to call a professional plumber.

What to Do When You Discover a Leaky Radiator

1. Identify the Leak Source

The first step is to locate the source of the leak. Here's what to look for:

• Radiator Body: A crack or hole in the radiator itself is less common but can occur, especially in older radiators. Look for any visible signs of water seeping from the body.
• Valve Connections: These are the most frequent culprits for leaks. Check the connection points between the radiator valves and the pipes feeding the radiator. Look for any dripping or dampness around these areas.
• Air Vent: The air vent is a small valve usually located at the top of the radiator. A faulty air vent can sometimes leak, but this is less common.

2. Take Safety Precautions

Before attempting any repairs, ensure safety:

• Turn Off the Heating System: Locate the boiler thermostat or control panel and turn off the heating. This will prevent hot water from circulating through the system.
• Turn Off the Water Supply: Identify the isolation valves controlling the water flow to the radiator. These are typically located near the boiler or under the floor where the pipes enter your home. Turn off both the hot and cold water supply valves for the affected radiator.
• Place a Container Underneath the Leak: Use a bucket or tray to catch any dripping water and prevent further damage to your floor or surrounding areas.

3. Potential DIY Solutions For Small Leaks

For minor leaks, you might be able to implement a temporary fix until a professional plumber arrives. Here are two options to consider, but proceed with caution and only if you feel comfortable:

• Tightening the Valve Gland Nut: The valve gland nut is located on the body of the valve, typically where the handle connects. Using an adjustable spanner, carefully tighten the nut in a clockwise direction. Avoid over-tightening, as this could damage the valve. If tightening the nut stops the leak, you've bought yourself some time until a professional service.
• Using a Radiator Leak Sealer: These are temporary solutions available at hardware stores. Follow the product instructions carefully, ensuring the system is cool and depressurised before applying the sealant. Remember, leak sealers are a temporary fix and might not be suitable for all leak types.

4. When to Call a Professional Plumber

If the leak persists after attempting a DIY solution, the leak is significant, or you're unsure about the source, it's crucial to call a qualified plumber.

Professional plumbers have the experience and tools to diagnose the leak accurately and implement a permanent solution.
