The Bldg Regs and the Environmental Guidelines require any abandoned soil or sewage leg to be rooted out and plugged off at the next live connection ie. an IC or MH. Because they become homes to rats.
How many actually do this, typically, depends on how many BCO's are looking over their shoulders.
Hows about (if the outlet is accessable) fitting one of those plugs at the far end of the drain and pouring and ramming a sand and cement mix down to solve the rat problem ? Spose it depends how long the soil is
Old (abandoned) outside WC's make an ideal entrance/exit for rats. The pipework is dry, the WC doesnt contain any water in the pan as it hasn't been used for years and the rats can come and go as they please with minimal disturbance! The initial extra work involved in sealing a redundant drain off properly is worth it long term to prevent giving the little blighters an easy life. Despite their disease ridden lifestyle, they are clever beggars and if there is an escape route, they will find it!
