[QUOTE="Mr Sworld, post: 35830, member: 184"] It tripped out again today! X( However this time the fault lasted long enough to figure out what the problem was! It wasn't the lead after all, it was the CH/HW system! So after opening up the wiring centre (which resembled a dogs dinner, why can't plumbers follow the wiring diagram?) I unwired each bit. Not the pump! Not the room Stat. Or the tank Stat either! Not the controller. Which left the 3-way valve. So unhooked that and the rcd stayed on! Success! :D Opened up the top and found a small amount of water leaking from the valve and just touching the pcb board! Dried it up and reconnected the valve wiring and all stays on! Now how the hell you would of had a chance of diagnoising that if you were called out for it I would have no idea! A random rcd event that would clear as soon as you reset the trip sometimes.....
