In which case the next question is "How do you find the soakaway?".

Its marked on the plans?


Errr.....which particular plans would these be?
I don't have any for my 1930s semi.
Are you saying that someone else will hold a set of definitive plans?
Including any changes to soakaways since the 1930s?
