1) The pump head stzt only loosely on top of it, if you come on the other hand it falls mostly down to the ground. But sticking works Aich not really.
2) The transparent hose has come loose at MRI, that I could from below no more shampoo pumping. I then removed the pump, cleaned and allowed to dry and then the hose with some superglue on the pump center part stuck, now it works fine!
