Cast iron wall plate on the boundary wall of the property facing the road between lamppost No14 and gateway to the house. The original access cover is in the road directly opposite the plate and is marked ‘AV.’
A late Victorian/early Edwardian Air Valve plate that would have been used to indicate where access to the valve could be located under the road surface. Air valves were used to release air pockets that could become trapped at high points of the water supply mains. This one is at the apex of Compton Place Road before it turns the corner and drops back down towards Borough Lane. It would have been installed at the same time as the adjacent Main Cock plate.
