To bleed a radiator with a screw-type valve, you'll need to release trapped air using the valve, typically with a radiator key or screwdriver. Here's a straightforward guide based on available information:
Step-by-Step Guide to Bleeding a Radiator
Here is a step-by-step guide to bleeding your radiator:
-
Preparation:
- Gather your tools: You'll need a radiator key (or a flat-head screwdriver if the valve has a slot), and a towel or container to catch any water.
- Protect the area: Place the towel or container just below the bleed valve to prevent water from dripping and causing damage.
-
Locate the Bleed Valve: The bleed valve is usually a small screw or a small key-operated valve located at the top of one end of the radiator.
-
Open the Valve:
- Insert the radiator key into the bleed valve. If it's a screw type, use a screwdriver.
- Slowly turn the key or screwdriver counterclockwise. Only turn it a little bit. You should hear a hissing sound as air escapes.
-
Release the Air:
- Allow the air to escape until water starts to come out. Be patient, as it may take a few moments.
- According to the provided reference, "water is coming straight out of that so we know this radiator is nicely topped. Up." This indicates that once water flows out steadily, the radiator is properly bled.
-
Close the Valve:
- Once water appears, carefully close the bleed valve by turning the key or screwdriver clockwise. Don't overtighten it.
-
Check Pressure and Repeat:
- After bleeding all radiators, check the boiler pressure. If it's low, you may need to add water to the system.
- Repeat the process if necessary.
Important Considerations
- Safety: Be careful when bleeding radiators, as the water can be hot.
- Systematic Approach: Start with the radiators furthest from the boiler and work your way closer.
- Monitor Boiler Pressure: Bleeding radiators can sometimes reduce boiler pressure, so keep an eye on it.
