Defense Case:
Another report is on June 6, 2016, a 'flood in courtyard' of the neonatal unit. Mr Mansutti says this may have followed a heavy downpour. He does not believe the foul drainage runs that way, so it would more likely be surface water.
Another report is on July 5, 2016, in ward 35/CLS, for 'various plumbing jobs in NNU'.
'Check pall water filters for poor flow'
'Check that all valves in the ceiling void are fully open - NNU and by theatres...'
'Leaking sink in Sluiceroom - please check'.
Mr Myers asks about the last of these jobs.
Mr Mansutti says it is likely a leak in one of the sinks. He says there is not a Sluiceroom in the neonatal unit.

Nicholas Johnson KC, for the prosecution, asks Mr Mansutti questions.
Mr Mansutti agrees that one of the problems for the flooding was adults 'putting things down sinks'.
One incident is somebody 'forcing a wipe towel down a sink'. Mr Mansutti accepts an incident did take place.
He says none of the incidents led to no hand washing facilities availability, and there is a system in place.
He says there has been 'sewage floods' in the neonatal unit. He says there was once incident, undated, not on a Datix form, where there was sewage on neonatal unit room 1.
He says he has knowledge of it because of "disgust", and work was done on moving sewage pipes away from the unit room in future, "so it couldn't happen again".
He says, for his recollection, it was a "one-off".
Mr Johnson says half the incidents listed did not take place in the neonatal unit. Mr Mansutti says there would not have been a direct effect on that unit for those days.

That completes Mr Mansutti's evidence.
It also completes the evidence presented in the Lucy Letby trial.
The trial judge, Mr Justice James Goss, is now giving preliminary directions to the jury.
11:40am
The trial judge says he has to discuss his directions of law with the prosecution and defence before he can deliver them to the jury.
He says those will likely be presented to the jury on Thursday, and the jury will not be present in court 'for very long'.
11:42am
The judge says the week beginning July 3 is when the jury will be expected to go out.
He says it is in the "hope and expectation that nothing untoward occurs", as the trial has had delays and it has gone on longer than expected.
11:43am
He also reminds the jurors of their obligations not to discuss the case with anyone, and not to discuss it amongst themselves until they are sent to deliberate.
11:44am
The jury are now sent home for the day.
