Hmmm... i think the temperature is now the problem, not the snow
We just had the washing machine on, and the missus just heard a trickling sound, and we ran to the kitchen and the whole sink was overflowing and dripping down the cupboards... i went outside and the grid was clear, but i put my finger up the whole (!) and the washing machine outlet pipe had frozen over!!! All the washing machine water came back into the house.
