Great that I should only find this out when it floods my bathroom, my hallway, and into Chloe's bedroom. Unfortunately, the properties of both water and gravity being what they are this has meant damage to the walls and ceilings of the same rooms in the flat downstairs. I await the response from Taylor Wimpey to discover if they will accept that this has been caused by their workmanship, or if I will end up having to speak to my insurers...
Smile, it could be worse ? I did. I smiled, now look what happened. Grrrrrrr.
