hi guys just been to look at a halstead eden sbx 30 no heating got hot water which pointed me straight to the diverter value but seeing as i have not worked on these before like some input from anyone firmiliar with these!!you got the hydrovalve which is attached to the pump with the diverter value which is a detachable unit underneath it spoke with thier technical department to see which one they reckoned it was reply given said there should be movement of about 2mm when manually moving the diverter when you put your fingers up inside the hydrovalue but impossible to tell if i was getting 2mm of movement is there any test i can do on the diverter motor which detaches?thinking of just changing the hydrovalue and see if that does it as they are priced separately,may thanks for any input guys
