A 2 port motorised valve I fitted around 18 months ago still works fine but has suddenly developed a small leak after everything cools down overnight; the leak quickly disappears when the boiler fires up in the morning. The valve is tucked away behind the boiler & so it’s not easy to establish exactly where the leak is coming from without removing it. I’m obviously going to have to drain the system down but I've not had one of these valves apart before; I assume there is a gasket between the brass valve body & the motor plate &, presumably, a ring seal on the motor drive shaft itself? Is this leak likely to be easy to repair once the valve is removed or should I just bite the bullet, get the plastic out & buy a new valve.
I obviously want a direct replacement without having to mess around modifying the boiler pipe work but I’m not particularly impressed by the current unit (Tower VAL222MP) lasting just 18 months; are all valve bodies made to a standard dimension across the fittings? Any suggestions for a more reliable unit?
