- Reference Number : I05
- Decision Date : June 2001 (Revised October 2011)
Where pipes, other than under floor heating pipes, are to be installed in solid floors, they shall be in a duct or chase which permits withdrawal of the pipe or provides access to replace it and any associated fittings, if necessary. It will be satisfactory for the installation either to be of one length of pipe (i.e. without joints) or, alternatively, if joints are installed within the floor, for the installation to undergo a satisfactory witnessed pressure test.
