Problem with water runs is in old umbrella covering daughter (6,4)
I believe the answer is:
rising damp
'problem with water' is the definition.
'runs is in old umbrella covering daughter' is the wordplay.
'runs' becomes 'r' (cricket abbreviation).
'old umbrella' becomes 'gamp' (old-fashioned term for an umbrella).
'covering' means one lot of letters goes inside another.
'daughter' becomes 'd' (genealogical abbreviation).
'gamp' enclosing 'd' is 'gdamp'.
'r'+'is'+'in'+'gdamp'='RISING DAMP'
(Other definitions for rising damp that I've seen before include "problem home-owners may face" , "domestic problem" , "old comedy programme" , "Rebellion needs control" , "problem for propertied classes if it gets off the ground" .)
