Conor visited the stand of Pimlico Plumbers, London's largest independent plumbing company, and met a number of young people who have taken part in their apprenticeship programme.
The apprentices challenged Conor to mend a tap in the fastest time possible, competing against other Conservative MPs.
Pimlico Plumbers was founded by Charlie Mullins in 1979, who left school with no qualifications, but trained to be a plumber and is now Manging Director employing over 300 people.
