Problems with attic Water Tanks
Water tanks are rarely, if ever installed correctly. In fact as far as I can recall no house I have ever inspected has ever had all of the following in place:
A tight fitting lid on the water tank.
A fully insulated tank with the base exposed to a part of the attic floor which has been left un-insulated to allow the heat from the house below to keep the tank from freezing in the winter.
Fully lagged pipe-work, again to stop it freezing in winter causing leaks.
A fully insulated attic access hatch.
All of these issues are easy to fix and most homeowners would have no difficulty doing the work themselves, and yet they don’t.
