Following the upmarket refurbishment of a large period property a dispute arose over the water system installation within the building. The owner alleged that they suffered numerous leaks from the underfloor heating system pipework buried under the the downstairs corridors, kitchen, cinema room, garage and swimming pool. Our Client denied the leaks, claiming that the problems arose from insufficient servicing of the heating system.Our expert services were called upon with regard to the installation of piping systems in accordance with the water system design standards, with specific regard to the accessibility or otherwise of water fittings. As part of our investigations we considered the various amendments of the British Standard on Household Water System Design, the Institute of Plumbing Design Guide and the Water Regulations, with particular attention to their advise on the burial of water pipework within concrete structures. We considered the methods employed in the construction if the property's underfloor heating system and held several conferences with the defence Counsel.The case went to mediation and Counsel's defence was based on our expertise. The outcome of the mediation produced a favourable result for our Client.
