When I was redoing the plumbing to my hot water heater I accidentally dropped a pen cap down the vent stack/flu.
Will this cause any problems? Like melting or catching on fire?
Its going to take a good bit of time to unhook the gas line and empty the tank to be able to tip it so I can remove the flue baffle, because of where it is currently located.
I'd rather not spend all that time if its a nonissue. My hunch is that it could be.
thanks for your help,
