Today we were asked to check a tenants bathroom extractor fan, condensation was not being removed from the property.
When our engineer checked the extractor fan it was found to be in full working order. They then checked the ducting and roof terminal / cowl.
Ducting was not connected to roof terminal. The installer of the flexible ducting did NOT even bother cutting a hole in the roof to connect to the roof terminal.
Roof sarking broken, flexible ducting ‘stuffed in’
Effect of Fault
The condensation from the bathroom is extracted into the loft.
The loft is not ventilated so the condensation is being drawn back into the tenant’s home.
Install rigid ducting between the extractor fan and the roof terminal
