l think l have (not sure unless someone can tell me the difference) 2 2 port valves and they are'nt working.. The honeywells have levers on the side and are sloppy with no resistance...
Can l take the main cover of if it's the old type, as l would like to put some WD40 on the spindle to see if it's seized and that is the problem...
If this does not work can l buy a replacement motor/actuator instead of taking the whole lot off where l presume it would need the system draining..
Could someone tell me what size copper pipes they are to the port valves, is it 22mm...
