I recently purchased a new home and in the building and pest report and in it, it was mentioned that the hot water overflow requires diverting to a drain or further from the dwellings wall or footings. Excess water ponding alongside walls and into perimeter footings has the potential to cause rising damp, differential settlement and wall cracks over time. Is it possible to DIY this or do I need to get a licensed plumber to help with this as the job could be too big? Thanks!
