We recently had a deducted system installed. There was a water coming out of the safety pipe so I got up into the roof void to see what was happening. Was a bit shocked to find lots of the insulation just dumped to the sides and piled up in sections, where they didn't need piping, tape or fittings they just left them where they fell, stanley knife left behind and one of the braces between the joists is broken. I just can't fathom how someone would think this is acceptable. Out of sight out of mind. They were to attend yesterday to redo the piping, tidy up and check the system over, but as expected no one showed.
