Can i replace a Myson MPE322 three port valve with one from a different manufacturer?

Question

The boiler is the infamous Potterton Suprima - can i use an alternative valve e.g. Honeywell?

Answer 1

Yes any spring return 3 port valve will replace the Myson, just make sure that you get a mid position version and fit it the right way round!

Answer 2

You can use a honeywell if all the connections are the same. Make sure it is fitted correctly as there is an arrow on the valve.
