Please double check what head you need ie. 2 or 3. Hope this helps. **Q: What is the life of a myson 222 actuator** A: That’s a how long is a piece of string question. The one I replaced when I bought this one lasted about 15 years ## Customer Reviews ### ⭐⭐⭐⭐⭐ Superb Service and Product *by L***K on 6 December 2025* Superb delivery, a quick isolation of the heating system and 4 valve screws and 4 wires later the heating system is perfect.
