Rising Damp Smith (Don Warrington) is a planning student who claims to be the son of an African Chief. As a black man, he brings out the ill-informed fears and knee-jerk suspicions of Rigsby. However, the landlord quickly accepts his new tenant and henceforth regards him with a wary respect... wary because of Philip's intelligence and smooth manners, and especially because Miss Jones finds herself attracted to the handsome sophisticate. Of these four principal actors, only Beckinsale was a new recruit - the others had all played their roles in the original stage play. In the first series, there was another tenant
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
