<p>A valve assembly for opening and closing a discharge pipe in a building. A valve housing (31); a valve (40) mounted in the valve housing (31); and operating means for opening and closing the valve, typically a handle (42), wherein either the handle is removed or rendered non-operational, or the valve assembly is rendered non-operational, both being after the valve is opened. The valve assembly can be rendered non-operational by the use of a cap (45) which can be placed over the assembly. The assembly is used to test the integrity of the discharge pipe work of a building or stormwater pipes by closing the valve, filling the pipes to ensure there are no leaks, then opening the valve and rendering it non-operational or preventing unauthorised access, to ensure it remains open for the life of the pipe work.</p> |
