Hi there. Just curious.....heavy DIY'er....just soldered to vertical coupling close to the floorboards (pipes coming vertically up from the void). Some flux - LA-CO - melted under the torch and ran down the pipe below the floorboards. Should I be worried?...keen to do a good job...and not create a problem in 10-20 years time!! Must say I'm a little confused between active/passive/acidic/non-acidic fluxes anyhow and how aggressive they are after the joint has been made....cheers for any info
