Guys, Many thanks for all your help. I could not purchase a diverter front section so changed the diverter valve. Everything now working fine. Cheers, again. Scott

Hi, the leak is from the back of diaphragm unit of the DHW valve, it is emitting from the spare securing screw hole. When you say the the front seal of the manifold block I am confused as where you mean. The diverter/3 way valve has: DHW flow valve, Primary flow valve, by pass section and...

It does sound like a diverter seal, suppose from a commercial view point replacing the diverter would be a better option although it could be a gamble that one seal may be all that is needed - naturally replacing them all anyway. Not too sure where the back pin on the front housing assembly...

Hi, I agree that it is probably leaking from behind the diaphragm. When the water is off the pressure in the heating loop gradually drops away to nothing. As soon as there is pressure back into the filling loop then the leak begins. When the system is delivering i.e. the heating system is on...

Hi, sorry. The water is leaking from the front cover of the DHW not from the centre but the bottom of the diaphragm housing. The Diaphragm seems intact and the housing appears undamaged. It appears to me that pressure is forcing its way passed the seal. When the heating system is running then...

Hi can you help a dummy? There is a constant water leak from the DHW vale at the diaphragm housing. Both the diverter and DHW diaphragms have been replaced. When there is flow/demand on the system the leak stops. Both the plungers are lifting the micro-switches OK. Pressure in the line naturally...
