It's so easy to fit.


All you need are a drill, some small screws, up to 10mm, a 32mm push-fit pipe fitting and pipe. The urine can be diverted in to a container or piped out in to a ground soakaway, and the solids go in to a container via the rear section.


Your loo box top which your separator will fit in to is best at a 9mm thickness and upward.


Draw around the separator giving yourself space for your containers underneath; At least 10cm clearance from the sides of your box to allow for the containers and the pipework to fit. Once you have drawn around the separator you should cut at least 2cm inside of this line to allow a suitable circumference for flange play. Flange play is crucial.
