Steve Pritchard is a plumber who works for Reliable Building Ltd. Reliable Building is a large company specializing in luxury flat development in the Greater London area. Steve was one of the plumbers completing a 10-storey block of flats in Richmond when an incident occurred. On returning to work after the weekend break it was found that because of a leak in the kitchen of the seventh floor flat, water had been running from the flat into the hallway and stairs and into the flats below. The total cost of the damage to carpets and other fittings was estimated at around 20,000. It is also known that: Steve is an experienced plumber. The last job that Steve had been asked to do before leaving the site for the weekend was to fit the bathroom of the flat in which the leak occurred. Steve had been keen to get away promptly at the end of the day because he was going away for the weekend. There had been an argument between Steve and the site foreman about the amount of overtime Steve had worked the week before. Steve had left his tools in the bathroom to finish the fitting after the weekend.
