Needs to be between 18 and 90 mm fall per metre of pipe

90 mm in 1000? Thats nearly 1 in 10.
Put the pipe in so that the bubble on a metre spirit level is on one of the lines. That will give it -if I remember correctly, something like 1 in 400.
Well fine, but it will be outwith current English building regs, and I rather assumed that was the point of the question??

are published there including drainage, its quite suprising how much there is on something that at first glance seems as simple as drainage
1 in 60 to 1 in 100 is recommened fo pipes laid in the ground.
IIRC its a bit more for internal bog pipes.
If I remember correctly that would be a factor of 10x incorrect. S.b. One in Forty. For small non underground runs such as the o.p. is enqiring about a steeper fall is commonplace.
