Our HW is working fine by not CH. We have a 3port ACL valve as above connected to one pump. The pump's okay as it works for the HW, thermostat is okay so narrowed it down to valve. I can get it to work by moving over the lever/latch and heating now working but I obviously now think I need to replace this valve?
Now I've moved the lever over it hasn't moved back as I expected but at least we're warm! I assumed it would move back once the thermostat switched off the heating but it didn't.
Is it possible to just replace the electrical part, rather than remove the whole valve and drain system etc, if so will any ACL 3 port valve do the trick or do I need to find a direct replacement?
I assume the only problem we'll have until it's replaced is that when the HW is on and not the CH then the CH will heat as well?
