Hello all,
My Lochinvar Knight boiler had been working great but lately it keeps making the pipes bang which can be heard upstairs. I went into the basement and filmed it to give you folks a better idea of what's happening.
It seems like the primary pump keeps turning on/off on it's own even when the Tstats aren't calling for heat. The primary pump starts up and then shuts off immediately and it repeats for several minutes. The pump also gets super hot to touch as well. The only way I can get it to stop is to kill the power to the pump and boiler with the emergency switch. Any ideas?
EDIT: this site won't allow me to upload the video
TIA
