whats the rules with cylinders. got told that it has to go back 450mm before it goes up to vent. do other draw offs have to be under the vent straight off the top of the cylinder? or can they be teed above it? any help is appreciated
Its normal for the vent to be going upwards from beside the cylinder which usually means a 450 mm or thereabouts horizontal from the centre of the cylinder.
The only important thing is that the vent rises unrestricted and terminates above the cistern after going up about 450 mm ABOVE the level in the cistern.
