The stopcock is leaking again. The site of the leak is the blanking plug where a water meter would go. This is a recurrent problem probably due to the high water pressure (>5 bar).
Please could you find a permanent solution to this leak. 
The stopcocks are located under my neighbours dustbins at the entrance to the property. Please note that the position of the stopcocks is reversed and that my stopcock is the one furthest from my house, the one nearest to my house supplies my neighbours.
