advice on moving central heating drain valve please?

[jphenning]

Hi
My central heating drain point is under a loose floorboard in my hall. I plan to lay oak flooring in the hall so it will become impossible to access this. Is it possible to move the drain valve to one of the pipes feeding the radiator ib the hall above the floorboards.

Not as effective if you do that but is common, would be better if you could route the existing one to outside then fit a drain down outside the premises and leave the existing one in the open position but if you want to use a downstairs rad pick one near a door that you can get a hose to outside and replace the Lockshield rad valve on that rad with a combined Lockshield and drain down valve
