Overflow relief gully installation requirements

Careful consideration is needed at the commencement of the job to establish expectations about:

  • finished floor and external ground levels, and
  • the appropriate placement of the overflow relief gully 

to enable compliance with the finished height requirements.

The ORG instillation requirements are the minimum requirements that need to be complied with.
