Gas boiler fires up but quickly shuts down

paddy07

At the weekend whilst screwing our floor boards back down, I nicked a central heating pipe. We drained the system and relaced the hole with a compression joint. We then bled the sytem, however now when the system calls for Heat (Heating or hot water) the bolier fires up for a short while (up to a couple of minutes), then switches back off. The pump is still pumping and seems to get very hot?

Does anybody have any ideas what I can do?

Thanks

From what you have described, it sounds like you have not properly bled the system. Depending on your particular pump, you may have a bleed cap on it, to get the air out of the pump, usually on the centre line of the impeller, if that makes sense.

I have hot water and less ear ache from nagging (winding me up) at what i had done.

If the pump is getting hotter than before it could be seized, does it sound like it is rotating?
