I cant believe there are all these replies and no one has mentioned the proper way to check a spirit level well here goes (for those who don't know).........
Place the level either vertical or horizontal (depending on what bubble maybe out) on a flat wall, set it so the bubble is dead centre now draw a pencil line along the length of the level. Now flip the level end to end set it on the pencil line and bubble centred again now if the line is still touching the level all the way along its spot on. If its not touching all the way then the distance it is away from the line at one end is double the distance that your level is out by.
