RAH Consultancy was contacted by Mr and Mrs Fletcher, the owners of a property in Barmouth, North Wales regarding the installation of the hot and cold water and heating system within their premise. This was a large property with included four en-suite facilities, underfloor heating and a granny flat.It was quickly established that there were many problems with the installed system. These problems included undersized piping throughout, undersized hot water cylinder and uninsulated heating pipes in the underfloor void. The installer had broken through the hung concrete floor to gain access to the void, compromising the floor's integrity in the process.RAH provided a detailed report as to the systems shortcomings relating to the Water Regulations and to BS 6700 and the Plumbing Design Guide. Negotiations with the builder as to the required remedial actions were protracted. However, the builder's did eventually agree with the findings of our report.The entire plumbing system was redesigned by ourselves. Calculations for flows, pipe sizing and heating requirements were undertaken. Working drawings were provided and the entire plumbing system re-installed in accordance with best practice. The plumbing works were overseen by ourselves, and were installed and commissioned to the complete satisfaction of the building's owners. This process avoided a possible lengthy court case.
