Hi, this is a carry on from my other thread as the title is wrong now as I don't seem to have a 'Pumping Over' problem, thread here: //www.diynot.com/forums/viewtopic.php?t=173134
What I'd now like to check is if the Boiler Pump Over-Run is working correctly, does it even have one?
This is what seems to be happening:
When the room stat stops calling for heat, the pump seems to stop instantly when the boiler shut down, it waits 15-20secs then starts for another 10secs, this senario results in banging in the boiler.
If I turn the stat up and let the boiler turn off itself the pump continues to run, and then I get no noise.
Any help appreciated
