**Q: My honeywell mid position valve has 5 wires but the myson mid position has 4 will it still work? there is no white wire?**
A: Are you sure you need this model as my actuator head was for a 2 port not a 3 port mid position valve. 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

*by J***5 on 5 February 2021*

Like for like and easy to install. If changing yourself, it is vital that you isolate your boiler from the power supply along with the system as there is a direct live from the boiler. Not an electrician or plumber but found this out on-line. This is my fourth in 12 years. They break and the manufacturer needs to get this sorted.
