I'm just having a boiler swap and got the news that it looks like the piping in my house might be lead.
Plumber says it might be a summer job to get the pipes replaced but is it really necessary? He's said that the pressure increases a lot with combis and there's an increased risk of burst pipes. He also mentioned that he's known of lead pipes lasting 10 years after a combi was installed.
I know nothing about central heating, so any advice is much appreciated.
