My Philips PerfectDraft starts to flow when positioning the tube
In the unfortunate event that your Philips PerfectDraft starts to flow when you position the tube, there could be some reasons for this. Please read about this in the following lines.
The tube was not positioned correctly
Reinstall the tube by sliding it into the tap unit and pushing it down until you hear a 'click'. If you can move the arm of the connection top freely up and down, the tap unit is placed properly on the keg.
The tube may be broken
Remove the tube from the tap unit and attach a new one.
