Rising Damp de la Tour, Richard Beckinsale and Don Warrington. Rossiter played Rupert Rigsby (originally Rooksby in the stage play), the miserly, seedy, and ludicrously self-regarding landlord of a run-down Victorian townhouse who rents out his shabby bedsits to a variety of tenants. Beckinsale played Alan Moore, a long-haired, naive, good-natured and amiable medical student who occupies the top room. Frances de la Tour played Ruth Jones, a fey, whimsical spinster and college administrator who rents another room, with whom Rigsby is in love and to whom he proposes in the last episode. In the pilot episode, a new tenant arrives. Philip
Damp (structural) salt accumulations still persist. This suggests that rising damp is not always the cause for the water penetration. The Building Research Establishment (BRE) in its review concludes that rising damp is a real problem. According to Jurin's law the maximum height of rise is inversely proportional to the capillary radius. Taking a typical pore radius for building materials of 1 µm, Jurin's Law would give a maximum rise of about 15 m, however, due to the effects of evaporation, in practice the rise would be considerably lower. A physical model of rising damp was developed by Christopher Hall and William
