Do I need to seal anything prior to the test?

20 Apr 2018 at 10:02 PM

All features which are designed for ventilation purposes should be closed or sealed, these include: extract vents, extract fans, window trickle vents, air conditioning ducts, and chimneys. All toilets, basins, and other wet drain areas must contain water to ensure a seal is made between the internal building space and sewerage system.

Please do not tape or cover over anything else, as the engineer will have to remove it!
