Frequently Asked Questions (FAQs)

1. What size are old radiator valves?

15mm valves are the only size you're likely to encounter, since 15mm copper pipes are the most common. There are also other sizes, from 8mm to 28mm, and there are accompanying adapters.

2. Do radiator valves fit all radiators?

You'll probably need a set of 15mm valves for your radiator, but if you're unsure then measure the diameter of your copper pipes to double check. The connection between your valve and the radiator is standard across all moderns radiators and valves.

3. Where is the bleed valve on a cast iron radiator?

Locate the bleed valve: the valve will be at the top of the radiator on either side and will look like a round hole with a square inside. Put your old towels down on the floor underneath it with the container on top to catch any water. Note: on modern cast iron radiators, it might be brass and hand-operated.

4. How do I know what type of radiator valve I have?

Anywhere your radiator has to make a 90° connection on the vertical plane, an angled radiator valve is needed. A quick rule of thumb is this: If the right angle is up and in, you need an angled valve. If the right angle is out (i.e. protrudes towards you) and in, you need a corner valve.
