How well does bunging the cold feed and Open vent work Discussion Thread
Have a radiator to swap. I'm thinking of piping back to the current supplies. The rad is slightly smaller. The connecting on the the old pipes at the end one by one. Would using bungs in the open vent a cold feed create enough of a vacuum for me to do this? Which a drain down. Thanks
