I have never understood this requirement. Most of the time if we have to flow from the top we achieve the 500 gpm through one valve. We have also used the valve on the landing below due to the absence of 2 at the top.

Most buidings I come across (maybe 95%) have sloped roofs. If the additional hose valve is provided, is it really used for testing? Or is it provided, just 'cos the code requires it? I would also like to hear from those that don't provide the additional hose connection for testing.

If there is no access and the pitch is less than 4/12 then we have been providing a control valve inside the stair well with some galv pipe going through the roof to the 2 hose valves.

I've never seen an additional hose connection being provided. I've been told by contractors that the hose connection at the highest floor level can be used for this purpose, which would be a difficult task as most buildings don't have access to the roof. What is the normal practice out there?
